add-on for the GNU C Library (glibc). +It contains code that is not maintained in the official glibc source tree. + +This includes working ports to GNU/Linux on some machine architectures that +are not maintained in the official glibc source tree. It also includes +some code once used by old libc ports now defunct, which has been abandoned +but may be useful for some future porter to examine. It may also include +some optimized functions tailored for specific CPU implementations of an +architecture, to be selected using --with-cpu. + +The ports repository is cooperatively maintained by volunteers on the +<libc-ports@sourceware.org> mailing list, and housed in a separate +ports git repository. See +http://www.gnu.org/software/libc/download.html for details on using +git. To report a bug in code housed in the ports repository, please +go to http://sources.redhat.com/bugzilla/ and file a bug report under +the glibc "ports" component. + +An add-on for an individual port can be made from just the sysdeps/ +subdirectories containing the port's code. You may want to include a +README and Banner of your own talking about your port's code in particular, +rather than the generic ones here. + +The real source code for any ports is found in the sysdeps/ subdirectories. +These should be exactly what would go into the main libc source tree if you +were to incorporate it directly. The only exceptions are the files +sysdeps/*/preconfigure and sysdeps/*/preconfigure.in; these are fragments +used by this add-on's configure fragment. The purpose of these is to set +$base_machine et al when the main libc configure's defaults are not right +for some machine. Everything else can and should be done from a normal +sysdeps/.../configure fragment that is used only when the configuration +selects that sysdeps subdirectory. Each port that requires some special +treatment before the sysdeps directory list is calculated, should add a +sysdeps/CPU/preconfigure file; this can either be written by hand or +generated by Autoconf from sysdeps/CPU/preconfigure.in, and follow the +rules for glibc add-on configure fragments. No preconfigure file should do +anything on an unrelated configuration, so that disparate ports can be put +into a single add-on without interfering with each other. Files that +would go in scripts/data/ for libc go in data/ in ports. + +Like all glibc add-ons, this must be used by specifying the directory in +the --enable-add-ons option when running glibc's configure script. + +The GNU C Library is free software. See the file COPYING.LIB in the +libc repository for copying conditions, and LICENSES for notices about +a few contributions that require these additional notices to be +distributed. License copyright years may be listed using range +notation, e.g., 2000-2011, indicating that every year in the range, +inclusive, is a copyrightable year that would otherwise be listed +individually.

The basic idea is that in +// order to compute logl(Arg) for an argument Arg in [1,2), +// we construct a value G such that G*Arg is close to 1 and that +// logl(1/G) is obtainable easily from a table of values calculated +// beforehand. Thus +// +// logl(Arg) = logl(1/G) + logl((G*Arg - 1)) +// +// Because |G*Arg - 1| is small, the second term on the right hand +// side can be approximated by a short polynomial. We elaborate +// this method in four steps. +// +// Step 0: Initialization +// +// We need to calculate logl( X+1 ). Obtain N, S_hi such that +// +// X = 2^N * ( S_hi + S_lo ) exactly +// +// where S_hi in [1,2) and S_lo is a correction to S_hi in the sense +// that |S_lo| <= ulp(S_hi). +// +// For the special version of logl: S_lo = b_lo +// !-----------------------------------------------! +// +// Step 1: Argument Reduction +// +// Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate +// +// G := G_1 * G_2 * G_3 +// r := (G * S_hi - 1) + G * S_lo +// +// These G_j's have the property that the product is exactly +// representable and that |r| < 2^(-12) as a result. +// +// Step 2: Approximation +// +// logl(1 + r) is approximated by a short polynomial poly(r). +// +// Step 3: Reconstruction +// +// Finally, logl( X ) = logl( X+1 ) is given by +// +// logl( X ) = logl( 2^N * (S_hi + S_lo) ) +// ~=~ N*logl(2) + logl(1/G) + logl(1 + r) +// ~=~ N*logl(2) + logl(1/G) + poly(r). +// +// For detailed description see logl or log1pl function, regular path. +// +// Registers used

+//============================================================== +// 02/02/00 Initial version +// 08/17/00 New and much faster algorithm. +// 08/31/00 Avoided bank conflicts on loads, shortened |x|=1 path, +// fixed mfb split issue stalls. +// 12/19/00 Fixed small arg cases to force inexact, or inexact and underflow. +// 08/02/02 New and much faster algorithm II +// 02/06/03 Reordered header: .section, .global, .proc, .align + +// Description +//========================================= +// The asin function computes the principal value of the arc sine of x. +// asin(0) returns 0, asin(1) returns pi/2, asin(-1) returns -pi/2. +// A doman error occurs for arguments not in the range [-1,+1]. +// +// The asin function returns the arc sine in the range [-pi/2, +pi/2] radians. +// +// There are 8 paths: +// 1. x = +/-0.0 +// Return asin(x) = +/-0.0 +// +// 2. 0.0 < |x| < 0.625 +// Return asin(x) = x + x^3 *PolA(x^2) +// where PolA(x^2) = A3 + A5*x^2 + A7*x^4 +...+ A35*x^32 +// +// 3. 0.625 <=|x| < 1.0 +// Return asin(x) = sign(x) * ( Pi/2 - sqrt(R) * PolB(R)) +// Where R = 1 - |x|, +// PolB(R) = B0 + B1*R + B2*R^2 +...+B12*R^12 +// +// sqrt(R) is approximated using the following sequence: +// y0 = (1 + eps)/sqrt(R) - initial approximation by frsqrta, +// |eps| < 2^(-8) +// Then 3 iterations are used to refine the result: +// H0 = 0.5*y0 +// S0 = R*y0 +// +// d0 = 0.5 - H0*S0 +// H1 = H0 + d0*H0 +// S1 = S0 + d0*S0 +// +// d1 = 0.5 - H1*S1 +// H2 = H1 + d0*H1 +// S2 = S1 + d0*S1 +// +// d2 = 0.5 - H2*S2 +// S3 = S3 + d2*S3 +// +// S3 approximates sqrt(R) with enough accuracy for this algorithm +// +// So, the result should be reconstracted as follows: +// asin(x) = sign(x) * (Pi/2 - S3*PolB(R)) +// +// But for optimization perposes the reconstruction step is slightly +// changed: +// asin(x) = sign(x)*(Pi/2 - PolB(R)*S2) + sign(x)*d2*S2*PolB(R) +// +// 4. |x| = 1.0 +// Return asin(x) = sign(x)*Pi/2 +// +// 5. 1.0 < |x| <= +INF +// A doman error occurs for

moved nan exit bundle up to gain a cycle. +// 08/08/00 Improved speed by avoiding SIR flush. +// 08/15/00 Bundle added after call to __libm_error_support to properly +// set [the previously overwritten] GR_Parameter_RESULT. +// 08/17/00 Changed predicate register macro-usage to direct predicate +// names due to an assembler bug. +// 10/17/00 Improved speed of x=0 and x=1 paths, set D flag if x denormal. +// 03/13/01 Corrected sign of imm1 value in dep instruction. +// 05/20/02 Cleaned up namespace and sf0 syntax +// 02/06/03 Reordered header: .section, .global, .proc, .align + +

The basic idea is that in +// order to compute logl(Arg) = log1pl (Arg-1) for an argument Arg in [1,2), +// we construct a value G such that G*Arg is close to 1 and that +// logl(1/G) is obtainable easily from a table of values calculated +// beforehand. Thus +// +// logl(Arg) = logl(1/G) + logl(G*Arg) +// = logl(1/G) + logl(1 + (G*Arg - 1)) +// +// Because |G*Arg - 1| is small, the second term on the right hand +// side can be approximated by a short polynomial. We elaborate +// this method in several steps. +// +// Step 0: Initialization +// ------ +// We need to calculate logl(X + X_lo + 1). Obtain N, S_hi such that +// +// X + X_lo + 1 = 2^N * ( S_hi + S_lo ) exactly +// +// where S_hi in [1,2) and S_lo is a correction to S_hi in the sense +// that |S_lo| <= ulp(S_hi). +// +// For the special version of log1p we add X_lo to S_lo (S_lo = S_lo + X_lo) +// !-----------------------------------------------------------------------! +// +// Step 1: Argument Reduction +// ------ +// Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate +// +// G := G_1 * G_2 * G_3 +// r := (G * S_hi - 1) + G * S_lo +// +// These G_j's have the property that the product is exactly +// representable and that |r| < 2^(-12) as a result. +// +// Step 2: Approximation +// ------ +// logl(1 + r) is approximated by a short polynomial poly(r). +// +// Step 3: Reconstruction +// ------ +// Finally, log1pl(X + X_lo) = logl(X + X_lo + 1) is given by +// +// logl(X + X_lo + 1) = logl(2^N * (S_hi + S_lo)) +// ~=~ N*logl(2) + logl(1/G) + logl(1 + r) +// ~=~ N*logl(2) + logl(1/G) + poly(r). +// +// For detailed description see log1p1 function, regular path. +// +//********************************************************************* + +RODATA +.align 64 + +// ************* DO NOT CHANGE THE ORDER OF THESE TABLES ************* + +LOCAL_OBJECT_START(Constants_TaylorSeries) +data8 0xF0F0F0F0F0F0F0F1,0x00003FFA // C17 +data8 0x8888888888888889,0x00003FFB // C15 +data8 0x9D89D89D89D89D8A,0x00003FFB // C13 +data8 0xBA2E8BA2E8BA2E8C,0x00003FFB // C11 +data8 0xE38E38E38E38E38E,0x00003FFB // C9 +data8 0x9249249249249249,0x00003FFC // C7 +data8 0xCCCCCCCCCCCCCCCD,0x00003FFC // C5 +data8 0xAAAAAAAAAAAAAAAA,0x00003FFD // C3 +data4 0x3f000000 // 1/2 +data4 0x00000000 // pad +data4 0x00000000 +data4 0x00000000 +LOCAL_OBJECT_END(Constants_TaylorSeries) + +LOCAL_OBJECT_START(Constants_Q) +data4 0x00000000,0xB1721800,0x00003FFE,0x00000000 // log2_hi +data4 0x4361C4C6,0x82E30865,0x0000BFE2,0x00000000 // log2_lo +data4 0x328833CB,0xCCCCCAF2,0x00003FFC,0x00000000 // Q4 +data4 0xA9D4BAFB,0x80000077,0x0000BFFD,0x00000000 // Q3 +data4 0xAAABE3D2,0xAAAAAAAA,0x00003FFD,0x00000000 // Q2 +data4 0xFFFFDAB7,0xFFFFFFFF,0x0000BFFD,0x00000000 // Q1 +LOCAL_OBJECT_END(Constants_Q) + + +// Z1 -

So we have following +// +// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256 +// +// and +// +// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) = +// = log(1 + r) + T +// +// The first value can be computed by polynomial P(r) approximating +// log(1 + r) on |r| < 1/256 and the second is precomputed tabular +// value defined by top 8 bit of f. +// +// Finally we have that log(x) ~ (N*log(2) + T) + P(r) +// +// Note that if input argument is close to 1.0 (in our case it means +// that |1 - x| < 1/256) we can use just polynomial approximation +// because x = 2^0 * f = f = 1 + r and +// log(x) = log(1 + r) ~ P(r) +// +// +// To compute log10(x) we just use identity: +// +// log10(x) = log(x)/log(10) +// +// so we have that +// +// log10(x) = (N*log(2) + T + log(1+r)) / log(10) = +// = N*(log(2)/log(10)) + (T/log(10)) + log(1 + r)/log(10) +// +// +// Implementation +// -------------- +// It can be seen that formulas for log and log10 differ from one another +// only by coefficients and tabular values. Namely as log as log10 are +// calculated as (N*L1 + T) + L2*Series(r) where in case of log +// L1 = log(2) +// T = log(1/frcpa(x)) +// L2 = 1.0 +// and in case of log10 +// L1 = log(2)/log(10) +// T = log(1/frcpa(x))/log(10) +// L2 = 1.0/log(10) +// +// So common code with two different entry points those set pointers +// to the base address of coresponding data sets containing values +// of L2,T and prepare integer representation of L1 needed for following +// setf instruction can be used. +// +// Note that both log and log10 use common approximation polynomial +// it means we need only one set of coefficients of approximation. +// +// 1. Computation of log(x) for |x-1| >= 1/256 +// InvX = frcpa(x) +// r = InvX*x - 1 +// P(r) = r*((1 - A2*r) + r^2*(A3 - A4*r)) = r*P2(r), +// A4,A3,A2 are created with setf inctruction. +// We use Taylor series and so A4 = 1/4, A3 = 1/3, +// A2 = 1/2 rounded to double. +// +// N = float(n) where n is true unbiased exponent of x +// +// T is tabular value of log(1/frcpa(x)) calculated in quad precision +// and rounded to double. To T we get bits from 55 to 62 of register +// format significand of x and calculate address +// ad_T = table_base_addr + 8 * index +// +// L2 (1.0 or 1.0/log(10) depending on function) is calculated in quad +// precision and rounded to double; it's loaded from memory +// +// L1 (log(2) or log10(2) depending on function) is calculated in quad +// precision and rounded to double; it's created with setf. +// +// And final result = P2(r)*(r*L2) + (T + N*L1) +// +// +// 2. Computation of log(x) for |x-1| < 1/256 +// r = x - 1 +// P(r) = r*((1 - A2*r) + r^2*(A3 - A4*r)) = r*P2(r), +// A4,A3,A2 are the same as in case |x-1| >= 1/256 +// +// And final result = P2(r)*(r*L2) +// +// 3. How we define is input argument such that |x-1| < 1/256 or not. +// +// To do it we analyze biased exponent and significand of input argment. +// +// a) First we test is biased exponent equal to 0xFFFE or 0xFFFF (i.e. +// we test is 0.5 <= x < 2). This comparison can be performed using +// unsigned version of cmp instruction in such a way +// biased_exponent_of_x - 0xFFFE < 2 +// +// +// b) Second (in case when result of a) is true) we need to compare x +// with 1-1/256 and 1+1/256 or in register format representation with +// 0xFFFEFF00000000000000 and 0xFFFF8080000000000000 correspondingly. +// As far as biased exponent of x here can be equal only to 0xFFFE or +// 0xFFFF we need to test only last bit of it. Also signifigand always +// has implicit bit set to 1 that can be exluded from comparison. +// Thus it's quite enough to generate 64-bit integer bits of that are +// ix[63] = biased_exponent_of_x[0] and ix[62-0] = significand_of_x[62-0] +// and compare it with 0x7F00000000000000 and 0x80800000000000000 (those +// obtained like ix from register representatinos of 255/256 and +// 257/256). This comparison can be made like in a), using unsigned +// version of cmp i.e. ix - 0x7F00000000000000 < 0x0180000000000000. +// 0x0180000000000000 is difference between 0x80800000000000000 and +// 0x7F00000000000000. +// +// Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are +// filtered and processed on special branches. +// +// +// Special values

The basic idea is that in +// order to compute logl(Arg) for an argument Arg in [1,2), we +// construct a value G such that G*Arg is close to 1 and that +// logl(1/G) is obtainable easily from a table of values calculated +// beforehand. Thus +// +// logl(Arg) = logl(1/G) + logl(G*Arg) +// = logl(1/G) + logl(1 + (G*Arg - 1)) +// +// Because |G*Arg - 1| is small, the second term on the right hand +// side can be approximated by a short polynomial. We elaborate +// this method in four steps. +// +// Step 0: Initialization +// +// We need to calculate logl( X ). Obtain N, S_hi such that +// +// X = 2^N * S_hi exactly +// +// where S_hi in [1,2) +// +// Step 1: Argument Reduction +// +// Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate +// +// G := G_1 * G_2 * G_3 +// r := (G * S_hi - 1) +// +// These G_j's have the property that the product is exactly +// representable and that |r| < 2^(-12) as a result. +// +// Step 2: Approximation +// +// +// logl(1 + r) is approximated by a short polynomial poly(r). +// +// Step 3: Reconstruction +// +// +// Finally, logl( X ) is given by +// +// logl( X ) = logl( 2^N * S_hi ) +// ~=~ N*logl(2) + logl(1/G) + logl(1 + r) +// ~=~ N*logl(2) + logl(1/G) + poly(r). +// +// IMPLEMENTATION +// +// Step 0. Initialization +// ---------------------- +// +// Z := X +// N := unbaised exponent of Z +// S_hi := 2^(-N) * Z +// +// Step 1. Argument Reduction +// -------------------------- +// +// Let +// +// Z = 2^N * S_hi = 2^N * 1.d_1 d_2 d_3 ... d_63 +// +// We obtain G_1, G_2, G_3 by the following steps. +// +// +// Define X_0 := 1.d_1 d_2 ... d_14.

Approximation +// --------------------- +// +// This step computes an approximation to logl( 1 + r ) where r is the +// reduced argument just obtained.

Introduction +// =============== +// +// For the forward trigonometric functions sin, cos, sincos, and +// tan, the original algorithms for IA 64 handle arguments up to +// 1 ulp less than 2^63 in magnitude. For double-extended arguments x, +// |x| >= 2^63, this routine returns N and r_hi, r_lo where +// +// x is accurately approximated by +// 2*K*pi + N * pi/2 + r_hi + r_lo, |r_hi+r_lo| <= pi/4. +// CASE = 1 or 2. +// CASE is 1 unless |r_hi + r_lo| < 2^(-33). +// +// The exact value of K is not determined, but that information is +// not required in trigonometric function computations. +// +// We first assume the argument x in question satisfies x >= 2^(63). +// In particular, it is positive. Negative x can be handled by symmetry: +// +// -x is accurately approximated by +// -2*K*pi + (-N) * pi/2 - (r_hi + r_lo), |r_hi+r_lo| <= pi/4. +// +// The idea of the reduction is that +// +// x * 2/pi = N_big + N + f, |f| <= 1/2 +// +// Moreover, for double extended x, |f| >= 2^(-75). (This is an +// non-obvious fact found by enumeration using a special algorithm +// involving continued fraction.) The algorithm described below +// calculates N and an accurate approximation of f. +// +// Roughly speaking, an appropriate 256-bit (4 X 64) portion of +// 2/pi is multiplied with x to give the desired information. +// +// II. Representation of 2/PI +// ========================== +// +// The value of 2/pi in binary fixed-point is +// +// .101000101111100110...... +// +// We store 2/pi in a table, starting at the position corresponding +// to bit position 63 +// +// bit position 63 62 ... 0 -1 -2 -3 -4 -5 -6 -7 .... -16576 +// +// 0 0 ... 0 . 1 0 1 0 1 0 1 .... X +// +// ^ +// |__ implied binary pt +// +// III. Algorithm +// ============== +// +// This describes the algorithm in the most natural way using +// unsigned interger multiplication. The implementation section +// describes how the integer arithmetic is simulated. +// +// STEP 0. Initialization +// ---------------------- +// +// Let the input argument x be +// +// x = 2^m * ( 1. b_1 b_2 b_3 ... b_63 ), 63 <= m <= 16383. +// +// The first crucial step is to fetch four 64-bit portions of 2/pi. +// To fulfill this goal, we calculate the bit position L of the +// beginning of these 256-bit quantity by +// +// L := 62 - m. +// +// Note that -16321 <= L <= -1 because 63 <= m <= 16383; and that +// the storage of 2/pi is adequate. +// +// Fetch P_1, P_2, P_3, P_4 beginning at bit position L thus: +// +// bit position L L-1 L-2 ... L-63 +// +// P_1 = b b b ... b +// +// each b can be 0 or 1. Also, let P_0 be the two bits correspoding to +// bit positions L+2 and L+1. So, when each of the P_j is interpreted +// with appropriate scaling, we have +// +// 2/pi = P_big + P_0 + (P_1 + P_2 + P_3 + P_4) + P_small +// +// Note that P_big and P_small can be ignored. The reasons are as follow. +// First, consider P_big. If P_big = 0, we can certainly ignore it. +// Otherwise, P_big >= 2^(L+3). Now, +// +// P_big * ulp(x) >= 2^(L+3) * 2^(m-63) +// >= 2^(65-m + m-63 ) +// >= 2^2 +// +// Thus, P_big * x is an integer of the form 4*K. So +// +// x = 4*K * (pi/2) + x*(P_0 + P_1 + P_2 + P_3 + P_4)*(pi/2) +// + x*P_small*(pi/2). +// +// Hence, P_big*x corresponds to information that can be ignored for +// trigonometic function evaluation. +// +// Next, we must estimate the effect of ignoring P_small. The absolute +// error made by ignoring P_small is bounded by +// +// |P_small * x| <= ulp(P_4) * x +// <= 2^(L-255) * 2^(m+1) +// <= 2^(62-m-255 + m + 1) +// <= 2^(-192) +// +// Since for double-extended precision, x * 2/pi = integer + f, +// 0.5 >= |f| >= 2^(-75), the relative error introduced by ignoring +// P_small is bounded by 2^(-192+75) <= 2^(-117), which is acceptable. +// +// Further note that if x is split into x_hi + x_lo where x_lo is the +// two bits corresponding to bit positions 2^(m-62) and 2^(m-63); then +// +// P_0 * x_hi +// +// is also an integer of the form 4*K; and thus can also be ignored. +// Let M := P_0 * x_lo which is a small integer. The main part of the +// calculation is really the multiplication of x with the four pieces +// P_1, P_2, P_3, and P_4. +// +// Unless the reduced argument is extremely small in magnitude, it +// suffices to carry out the multiplication of x with P_1, P_2, and +// P_3. x*P_4 will be carried out and added on as a correction only +// when it is found to be needed. Note also that x*P_4 need not be +// computed exactly. A straightforward multiplication suffices since +// the rounding error thus produced would be bounded by 2^(-3*64), +// that is 2^(-192) which is small enough as the reduced argument +// is bounded from below by 2^(-75). +// +// Now that we have four 64-bit data representing 2/pi and a +// 64-bit x. We first need to calculate a highly accurate product +// of x and P_1, P_2, P_3. This is best understood as integer +// multiplication. +// +// +// STEP 1.

Get N and f +// ------------------- +// +// Conceptually, after the individual pieces S_0, S_1, ..., are obtained, +// we have to sum them and obtain an integer part, N, and a fraction, f. +// Here, |f| <= 1/2, and N is an integer. Note also that N need only to +// be known to module 2^k, k >= 2. In the case when |f| is small enough, +// we would need to add in the value x*P_4. +// +// +// STEP 3. Get reduced argument +// ---------------------------- +// +// The value f is not yet the reduced argument that we seek. The +// equation +// +// x * 2/pi = 4K + N + f +// +// says that +// +// x = 2*K*pi + N * pi/2 + f * (pi/2). +// +// Thus, the reduced argument is given by +// +// reduced argument = f * pi/2. +// +// This multiplication must be performed to extra precision. +// +// IV.

Then +// +// sin( Arg ) = (-1)^i_0 sin( alpha ) if i_1 = 0, +// = (-1)^i_0 cos( alpha ) if i_1 = 1. +// +// For example: +// if M = -1, I = 11 +// sin ((-pi/2 + alpha) = (-1) cos (alpha) +// if M = 0, I = 00 +// sin (alpha) = sin (alpha) +// if M = 1, I = 01 +// sin (pi/2 + alpha) = cos (alpha) +// if M = 2, I = 10 +// sin (pi + alpha) = (-1) sin (alpha) +// if M = 3, I = 11 +// sin ((3/2)pi + alpha) = (-1) cos (alpha) +// +// The value of alpha is obtained by argument reduction and +// represented by two working precision numbers r and c where +// +// alpha = r + c accurately. +// +// The reduction method is described in a previous write up. +// The argument reduction scheme identifies 4 cases. For Cases 2 +// and 4, because |alpha| is small, sin(r+c) and cos(r+c) can be +// computed very easily by 2 or 3 terms of the Taylor series +// expansion as follows: +// +// Case 2: +// ------- +// +// sin(r + c) = r + c - r^3/6 accurately +// cos(r + c) = 1 - 2^(-67) accurately +// +// Case 4: +// ------- +// +// sin(r + c) = r + c - r^3/6 + r^5/120 accurately +// cos(r + c) = 1 - r^2/2 + r^4/24 accurately +// +// The only cases left are Cases 1 and 3 of the argument reduction +// procedure. These two cases will be merged since after the +// argument is reduced in either cases, we have the reduced argument +// represented as r + c and that the magnitude |r + c| is not small +// enough to allow the usage of a very short approximation. +// +// The required calculation is either +// +// sin(r + c) = sin(r) + correction, or +// cos(r + c) = cos(r) + correction. +// +// Specifically, +// +// sin(r + c) = sin(r) + c sin'(r) + O(c^2) +// = sin(r) + c cos (r) + O(c^2) +// = sin(r) + c(1 - r^2/2) accurately. +// Similarly, +// +// cos(r + c) = cos(r) - c sin(r) + O(c^2) +// = cos(r) - c(r - r^3/6) accurately. +// +// We therefore concentrate on accurately calculating sin(r) and +// cos(r) for a working-precision number r, |r| <= pi/4 to within +// 0.1% or so. +// +// The greatest challenge of this task is that the second terms of +// the Taylor series +// +// r - r^3/3! + r^r/5! - ... +// +// and +// +// 1 - r^2/2! + r^4/4! - ... +// +// are not very small when |r| is close to pi/4 and the rounding +// errors will be a concern if simple polynomial accumulation is +// used. When |r| < 2^-3, however, the second terms will be small +// enough (6 bits or so of right shift) that a normal Horner +// recurrence suffices. Hence there are two cases that we consider +// in the accurate computation of sin(r) and cos(r), |r| <= pi/4. +// +// Case small_r: |r| < 2^(-3) +// -------------------------- +// +// Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1], +// we have +// +// sin(Arg) = (-1)^i_0 * sin(r + c) if i_1 = 0 +// = (-1)^i_0 * cos(r + c) if i_1 = 1 +// +// can be accurately approximated by +// +// sin(Arg) = (-1)^i_0 * [sin(r) + c] if i_1 = 0 +// = (-1)^i_0 * [cos(r) - c*r] if i_1 = 1 +// +// because |r| is small and thus the second terms in the correction +// are unneccessary. +// +// Finally, sin(r) and cos(r) are approximated by polynomials of +// moderate lengths. +// +// sin(r) = r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11 +// cos(r) = 1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10 +// +// We can make use of predicates to selectively calculate +// sin(r) or cos(r) based on i_1. +// +// Case normal_r: 2^(-3) <= |r| <= pi/4 +// ------------------------------------ +// +// This case is more likely than the previous one if one considers +// r to be uniformly distributed in [-pi/4 pi/4]. Again, +// +// sin(Arg) = (-1)^i_0 * sin(r + c) if i_1 = 0 +// = (-1)^i_0 * cos(r + c) if i_1 = 1. +// +// Because |r| is now larger, we need one extra term in the +// correction. sin(Arg) can be accurately approximated by +// +// sin(Arg) = (-1)^i_0 * [sin(r) + c(1-r^2/2)] if i_1 = 0 +// = (-1)^i_0 * [cos(r) - c*r*(1 - r^2/6)] i_1 = 1. +// +// Finally, sin(r) and cos(r) are approximated by polynomials of +// moderate lengths. +// +// sin(r) = r + PP_1_hi r^3 + PP_1_lo r^3 + +// PP_2 r^5 + ... + PP_8 r^17 +// +// cos(r) = 1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16 +// +// where PP_1_hi is only about 16 bits long and QQ_1 is -1/2. +// The crux in accurate computation is to calculate +// +// r + PP_1_hi r^3 or 1 + QQ_1 r^2 +// +// accurately as two pieces: U_hi and U_lo. The way to achieve this +// is to obtain r_hi as a 10 sig. bit number that approximates r to +// roughly 8 bits or so of accuracy. (One convenient way is +// +// r_hi := frcpa( frcpa( r ) ).) +// +// This way, +// +// r + PP_1_hi r^3 = r + PP_1_hi r_hi^3 + +// PP_1_hi (r^3 - r_hi^3) +// = [r + PP_1_hi r_hi^3] + +// [PP_1_hi (r - r_hi) +// (r^2 + r_hi r + r_hi^2) ] +// = U_hi + U_lo +// +// Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long, +// PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed +// exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign +// and that there is no more than 8 bit shift off between r and +// PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus +// calculated without any error. Finally, the fact that +// +// |U_lo| <= 2^(-8) |U_hi| +// +// says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly +// 8 extra bits of accuracy. +// +// Similarly, +// +// 1 + QQ_1 r^2 = [1 + QQ_1 r_hi^2] + +// [QQ_1 (r - r_hi)(r + r_hi)] +// = U_hi + U_lo. +// +// Summarizing, we calculate r_hi = frcpa( frcpa( r ) ). +// +// If i_1 = 0, then +// +// U_hi := r + PP_1_hi * r_hi^3 +// U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2) +// poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17 +// correction := c * ( 1 + C_1 r^2 ) +// +// Else ...i_1 = 1 +// +// U_hi := 1 + QQ_1 * r_hi * r_hi +// U_lo := QQ_1 * (r - r_hi) * (r + r_hi) +// poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16 +// correction := -c * r * (1 + S_1 * r^2) +// +// End +// +// Finally, +// +// V := poly + ( U_lo + correction ) +// +// / U_hi + V if i_0 = 0 +// result := | +// \ (-U_hi) - V if i_0 = 1 +// +// It is important that in the last step, negation of U_hi is +// performed prior to the subtraction which is to be performed in +// the user-set rounding mode. +// +// +// Algorithmic Description +// ======================= +// +// The argument reduction algorithm is tightly integrated into FSIN +// and FCOS which share the same code.

Then +// +// sinl( Arg ) = (-1)^i_0 sinl( alpha ) if i_1 = 0, +// = (-1)^i_0 cosl( alpha ) if i_1 = 1. +// +// For example: +// if M = -1, I = 11 +// sin ((-pi/2 + alpha) = (-1) cos (alpha) +// if M = 0, I = 00 +// sin (alpha) = sin (alpha) +// if M = 1, I = 01 +// sin (pi/2 + alpha) = cos (alpha) +// if M = 2, I = 10 +// sin (pi + alpha) = (-1) sin (alpha) +// if M = 3, I = 11 +// sin ((3/2)pi + alpha) = (-1) cos (alpha) +// +// The value of alpha is obtained by argument reduction and +// represented by two working precision numbers r and c where +// +// alpha = r + c accurately. +// +// The reduction method is described in a previous write up. +// The argument reduction scheme identifies 4 cases. For Cases 2 +// and 4, because |alpha| is small, sinl(r+c) and cosl(r+c) can be +// computed very easily by 2 or 3 terms of the Taylor series +// expansion as follows: +// +// Case 2: +// ------- +// +// sinl(r + c) = r + c - r^3/6 accurately +// cosl(r + c) = 1 - 2^(-67) accurately +// +// Case 4: +// ------- +// +// sinl(r + c) = r + c - r^3/6 + r^5/120 accurately +// cosl(r + c) = 1 - r^2/2 + r^4/24 accurately +// +// The only cases left are Cases 1 and 3 of the argument reduction +// procedure. These two cases will be merged since after the +// argument is reduced in either cases, we have the reduced argument +// represented as r + c and that the magnitude |r + c| is not small +// enough to allow the usage of a very short approximation. +// +// The required calculation is either +// +// sinl(r + c) = sinl(r) + correction, or +// cosl(r + c) = cosl(r) + correction. +// +// Specifically, +// +// sinl(r + c) = sinl(r) + c sin'(r) + O(c^2) +// = sinl(r) + c cos (r) + O(c^2) +// = sinl(r) + c(1 - r^2/2) accurately. +// Similarly, +// +// cosl(r + c) = cosl(r) - c sinl(r) + O(c^2) +// = cosl(r) - c(r - r^3/6) accurately. +// +// We therefore concentrate on accurately calculating sinl(r) and +// cosl(r) for a working-precision number r, |r| <= pi/4 to within +// 0.1% or so. +// +// The greatest challenge of this task is that the second terms of +// the Taylor series +// +// r - r^3/3! + r^r/5! - ... +// +// and +// +// 1 - r^2/2! + r^4/4! - ... +// +// are not very small when |r| is close to pi/4 and the rounding +// errors will be a concern if simple polynomial accumulation is +// used. When |r| < 2^-3, however, the second terms will be small +// enough (6 bits or so of right shift) that a normal Horner +// recurrence suffices. Hence there are two cases that we consider +// in the accurate computation of sinl(r) and cosl(r), |r| <= pi/4. +// +// Case small_r: |r| < 2^(-3) +// -------------------------- +// +// Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1], +// we have +// +// sinl(Arg) = (-1)^i_0 * sinl(r + c) if i_1 = 0 +// = (-1)^i_0 * cosl(r + c) if i_1 = 1 +// +// can be accurately approximated by +// +// sinl(Arg) = (-1)^i_0 * [sinl(r) + c] if i_1 = 0 +// = (-1)^i_0 * [cosl(r) - c*r] if i_1 = 1 +// +// because |r| is small and thus the second terms in the correction +// are unneccessary. +// +// Finally, sinl(r) and cosl(r) are approximated by polynomials of +// moderate lengths. +// +// sinl(r) = r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11 +// cosl(r) = 1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10 +// +// We can make use of predicates to selectively calculate +// sinl(r) or cosl(r) based on i_1. +// +// Case normal_r: 2^(-3) <= |r| <= pi/4 +// ------------------------------------ +// +// This case is more likely than the previous one if one considers +// r to be uniformly distributed in [-pi/4 pi/4]. Again, +// +// sinl(Arg) = (-1)^i_0 * sinl(r + c) if i_1 = 0 +// = (-1)^i_0 * cosl(r + c) if i_1 = 1. +// +// Because |r| is now larger, we need one extra term in the +// correction. sinl(Arg) can be accurately approximated by +// +// sinl(Arg) = (-1)^i_0 * [sinl(r) + c(1-r^2/2)] if i_1 = 0 +// = (-1)^i_0 * [cosl(r) - c*r*(1 - r^2/6)] i_1 = 1. +// +// Finally, sinl(r) and cosl(r) are approximated by polynomials of +// moderate lengths. +// +// sinl(r) = r + PP_1_hi r^3 + PP_1_lo r^3 + +// PP_2 r^5 + ... + PP_8 r^17 +// +// cosl(r) = 1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16 +// +// where PP_1_hi is only about 16 bits long and QQ_1 is -1/2. +// The crux in accurate computation is to calculate +// +// r + PP_1_hi r^3 or 1 + QQ_1 r^2 +// +// accurately as two pieces: U_hi and U_lo. The way to achieve this +// is to obtain r_hi as a 10 sig. bit number that approximates r to +// roughly 8 bits or so of accuracy. (One convenient way is +// +// r_hi := frcpa( frcpa( r ) ).) +// +// This way, +// +// r + PP_1_hi r^3 = r + PP_1_hi r_hi^3 + +// PP_1_hi (r^3 - r_hi^3) +// = [r + PP_1_hi r_hi^3] + +// [PP_1_hi (r - r_hi) +// (r^2 + r_hi r + r_hi^2) ] +// = U_hi + U_lo +// +// Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long, +// PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed +// exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign +// and that there is no more than 8 bit shift off between r and +// PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus +// calculated without any error. Finally, the fact that +// +// |U_lo| <= 2^(-8) |U_hi| +// +// says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly +// 8 extra bits of accuracy. +// +// Similarly, +// +// 1 + QQ_1 r^2 = [1 + QQ_1 r_hi^2] + +// [QQ_1 (r - r_hi)(r + r_hi)] +// = U_hi + U_lo. +// +// Summarizing, we calculate r_hi = frcpa( frcpa( r ) ). +// +// If i_1 = 0, then +// +// U_hi := r + PP_1_hi * r_hi^3 +// U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2) +// poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17 +// correction := c * ( 1 + C_1 r^2 ) +// +// Else ...i_1 = 1 +// +// U_hi := 1 + QQ_1 * r_hi * r_hi +// U_lo := QQ_1 * (r - r_hi) * (r + r_hi) +// poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16 +// correction := -c * r * (1 + S_1 * r^2) +// +// End +// +// Finally, +// +// V := poly + ( U_lo + correction ) +// +// / U_hi + V if i_0 = 0 +// result := | +// \ (-U_hi) - V if i_0 = 1 +// +// It is important that in the last step, negation of U_hi is +// performed prior to the subtraction which is to be performed in +// the user-set rounding mode. +// +// +// Algorithmic Description +// ======================= +// +// The argument reduction algorithm shares the same code between FSIN and FCOS. +// The argument reduction description given +// previously is repeated below. +// +// +// Step 0.

Now, given +// +// Arg = N pi/2 + alpha, |alpha| <= pi/4, +// +// basic mathematical relationship shows that +// +// tan( Arg ) = tan( alpha ) if N is even; +// = -cot( alpha ) otherwise. +// +// The value of alpha is obtained by argument reduction and +// represented by two working precision numbers r and c where +// +// alpha = r + c accurately. +// +// The reduction method is described in a previous write up. +// The argument reduction scheme identifies 4 cases. For Cases 2 +// and 4, because |alpha| is small, tan(r+c) and -cot(r+c) can be +// computed very easily by 2 or 3 terms of the Taylor series +// expansion as follows: +// +// Case 2: +// ------- +// +// tan(r + c) = r + c + r^3/3 ...accurately +// -cot(r + c) = -1/(r+c) + r/3 ...accurately +// +// Case 4: +// ------- +// +// tan(r + c) = r + c + r^3/3 + 2r^5/15 ...accurately +// -cot(r + c) = -1/(r+c) + r/3 + r^3/45 ...accurately +// +// +// The only cases left are Cases 1 and 3 of the argument reduction +// procedure. These two cases will be merged since after the +// argument is reduced in either cases, we have the reduced argument +// represented as r + c and that the magnitude |r + c| is not small +// enough to allow the usage of a very short approximation. +// +// The greatest challenge of this task is that the second terms of +// the Taylor series for tan(r) and -cot(r) +// +// r + r^3/3 + 2 r^5/15 + ... +// +// and +// +// -1/r + r/3 + r^3/45 + ... +// +// are not very small when |r| is close to pi/4 and the rounding +// errors will be a concern if simple polynomial accumulation is +// used. When |r| < 2^(-2), however, the second terms will be small +// enough (5 bits or so of right shift) that a normal Horner +// recurrence suffices. Hence there are two cases that we consider +// in the accurate computation of tan(r) and cot(r), |r| <= pi/4. +// +// Case small_r: |r| < 2^(-2) +// -------------------------- +// +// Since Arg = N pi/4 + r + c accurately, we have +// +// tan(Arg) = tan(r+c) for N even, +// = -cot(r+c) otherwise. +// +// Here for this case, both tan(r) and -cot(r) can be approximated +// by simple polynomials: +// +// tan(r) = r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19 +// -cot(r) = -1/r + Q1_1 r + Q1_2 r^3 + ... + Q1_7 r^13 +// +// accurately. Since |r| is relatively small, tan(r+c) and +// -cot(r+c) can be accurately approximated by replacing r with +// r+c only in the first two terms of the corresponding polynomials. +// +// Note that P1_1 (and Q1_1 for that matter) approximates 1/3 to +// almost 64 sig. bits, thus +// +// P1_1 (r+c)^3 = P1_1 r^3 + c * r^2 accurately. +// +// Hence, +// +// tan(r+c) = r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19 +// + c*(1 + r^2) +// +// -cot(r+c) = -1/(r+c) + Q1_1 r + Q1_2 r^3 + ... + Q1_7 r^13 +// + Q1_1*c +// +// +// Case normal_r: 2^(-2) <= |r| <= pi/4 +// ------------------------------------ +// +// This case is more likely than the previous one if one considers +// r to be uniformly distributed in [-pi/4 pi/4]. +// +// The required calculation is either +// +// tan(r + c) = tan(r) + correction, or +// -cot(r + c) = -cot(r) + correction. +// +// Specifically, +// +// tan(r + c) = tan(r) + c tan'(r) + O(c^2) +// = tan(r) + c sec^2(r) + O(c^2) +// = tan(r) + c SEC_sq ...accurately +// as long as SEC_sq approximates sec^2(r) +// to, say, 5 bits or so. +// +// Similarly, +// +// -cot(r + c) = -cot(r) - c cot'(r) + O(c^2) +// = -cot(r) + c csc^2(r) + O(c^2) +// = -cot(r) + c CSC_sq ...accurately +// as long as CSC_sq approximates csc^2(r) +// to, say, 5 bits or so. +// +// We therefore concentrate on accurately calculating tan(r) and +// cot(r) for a working-precision number r, |r| <= pi/4 to within +// 0.1% or so. +// +// We will employ a table-driven approach. Let +// +// r = sgn_r * 2^k * 1.b_1 b_2 ... b_5 ... b_63 +// = sgn_r * ( B + x ) +// +// where +// +// B = 2^k * 1.b_1 b_2 ... b_5 1 +// x = |r| - B +// +// Now, +// tan(B) + tan(x) +// tan( B + x ) = ------------------------ +// 1 - tan(B)*tan(x) +// +// / \ +// | tan(B) + tan(x) | + +// = tan(B) + | ------------------------ - tan(B) | +// | 1 - tan(B)*tan(x) | +// \ / +// +// sec^2(B) * tan(x) +// = tan(B) + ------------------------ +// 1 - tan(B)*tan(x) +// +// (1/[sin(B)*cos(B)]) * tan(x) +// = tan(B) + -------------------------------- +// cot(B) - tan(x) +// +// +// Clearly, the values of tan(B), cot(B) and 1/(sin(B)*cos(B)) are +// calculated beforehand and stored in a table.

The basic idea is that in +// order to compute logl(Arg) = logl (Arg-1) for an argument Arg in [1,2), +// we construct a value G such that G*Arg is close to 1 and that +// logl(1/G) is obtainable easily from a table of values calculated +// beforehand. Thus +// +// logl(Arg) = logl(1/G) + logl((G*Arg - 1)) +// +// Because |G*Arg - 1| is small, the second term on the right hand +// side can be approximated by a short polynomial. We elaborate +// this method in four steps. +// +// Step 0: Initialization +// +// We need to calculate logl( X ). Obtain N, S_hi such that +// +// X = 2^N * ( S_hi + S_lo ) exactly +// +// where S_hi in [1,2) and S_lo is a correction to S_hi in the sense +// that |S_lo| <= ulp(S_hi). +// +// For the special version of logl: S_lo = b_lo +// !-----------------------------------------------! +// +// Step 1: Argument Reduction +// +// Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate +// +// G := G_1 * G_2 * G_3 +// r := (G * S_hi - 1) + G * S_lo +// +// These G_j's have the property that the product is exactly +// representable and that |r| < 2^(-12) as a result. +// +// Step 2: Approximation +// +// logl(1 + r) is approximated by a short polynomial poly(r). +// +// Step 3: Reconstruction +// +// Finally, +// +// logl( X ) = logl( 2^N * (S_hi + S_lo) ) +// ~=~ N*logl(2) + logl(1/G) + logl(1 + r) +// ~=~ N*logl(2) + logl(1/G) + poly(r). +// +// For detailed description see logl or log1pl function, regular path. +// +// Registers used

The main reason is that given any argument Arg, computation +// of trigonometric functions first calculate N and an approximation +// to alpha where +// +// Arg = N pi/2 + alpha, |alpha| <= pi/4. +// +// Since +// +// cosl( Arg ) = sinl( (N+1) pi/2 + alpha ), +// +// therefore, the code for computing sine will produce cosine as long +// as 1 is added to N immediately after the argument reduction +// process. +// +// Let M = N if sine +// N+1 if cosine. +// +// Now, given +// +// Arg = M pi/2 + alpha, |alpha| <= pi/4, +// +// let I = M mod 4, or I be the two lsb of M when M is represented +// as 2's complement. I = [i_0 i_1]. Then +// +// sinl( Arg ) = (-1)^i_0 sinl( alpha ) if i_1 = 0, +// = (-1)^i_0 cosl( alpha ) if i_1 = 1. +// +// For example: +// if M = -1, I = 11 +// sin ((-pi/2 + alpha) = (-1) cos (alpha) +// if M = 0, I = 00 +// sin (alpha) = sin (alpha) +// if M = 1, I = 01 +// sin (pi/2 + alpha) = cos (alpha) +// if M = 2, I = 10 +// sin (pi + alpha) = (-1) sin (alpha) +// if M = 3, I = 11 +// sin ((3/2)pi + alpha) = (-1) cos (alpha) +// +// The value of alpha is obtained by argument reduction and +// represented by two working precision numbers r and c where +// +// alpha = r + c accurately. +// +// The reduction method is described in a previous write up. +// The argument reduction scheme identifies 4 cases. For Cases 2 +// and 4, because |alpha| is small, sinl(r+c) and cosl(r+c) can be +// computed very easily by 2 or 3 terms of the Taylor series +// expansion as follows: +// +// Case 2: +// ------- +// +// sinl(r + c) = r + c - r^3/6 accurately +// cosl(r + c) = 1 - 2^(-67) accurately +// +// Case 4: +// ------- +// +// sinl(r + c) = r + c - r^3/6 + r^5/120 accurately +// cosl(r + c) = 1 - r^2/2 + r^4/24 accurately +// +// The only cases left are Cases 1 and 3 of the argument reduction +// procedure. These two cases will be merged since after the +// argument is reduced in either cases, we have the reduced argument +// represented as r + c and that the magnitude |r + c| is not small +// enough to allow the usage of a very short approximation. +// +// The required calculation is either +// +// sinl(r + c) = sinl(r) + correction, or +// cosl(r + c) = cosl(r) + correction. +// +// Specifically, +// +// sinl(r + c) = sinl(r) + c sin'(r) + O(c^2) +// = sinl(r) + c cos (r) + O(c^2) +// = sinl(r) + c(1 - r^2/2) accurately. +// Similarly, +// +// cosl(r + c) = cosl(r) - c sinl(r) + O(c^2) +// = cosl(r) - c(r - r^3/6) accurately. +// +// We therefore concentrate on accurately calculating sinl(r) and +// cosl(r) for a working-precision number r, |r| <= pi/4 to within +// 0.1% or so. +// +// The greatest challenge of this task is that the second terms of +// the Taylor series +// +// r - r^3/3! + r^r/5! - ... +// +// and +// +// 1 - r^2/2! + r^4/4! - ... +// +// are not very small when |r| is close to pi/4 and the rounding +// errors will be a concern if simple polynomial accumulation is +// used. When |r| < 2^-3, however, the second terms will be small +// enough (6 bits or so of right shift) that a normal Horner +// recurrence suffices. Hence there are two cases that we consider +// in the accurate computation of sinl(r) and cosl(r), |r| <= pi/4. +// +// Case small_r: |r| < 2^(-3) +// -------------------------- +// +// Since Arg = M pi/4 + r + c accurately, and M mod 4 is [i_0 i_1], +// we have +// +// sinl(Arg) = (-1)^i_0 * sinl(r + c) if i_1 = 0 +// = (-1)^i_0 * cosl(r + c) if i_1 = 1 +// +// can be accurately approximated by +// +// sinl(Arg) = (-1)^i_0 * [sinl(r) + c] if i_1 = 0 +// = (-1)^i_0 * [cosl(r) - c*r] if i_1 = 1 +// +// because |r| is small and thus the second terms in the correction +// are unneccessary. +// +// Finally, sinl(r) and cosl(r) are approximated by polynomials of +// moderate lengths. +// +// sinl(r) = r + S_1 r^3 + S_2 r^5 + ... + S_5 r^11 +// cosl(r) = 1 + C_1 r^2 + C_2 r^4 + ... + C_5 r^10 +// +// We can make use of predicates to selectively calculate +// sinl(r) or cosl(r) based on i_1. +// +// Case normal_r: 2^(-3) <= |r| <= pi/4 +// ------------------------------------ +// +// This case is more likely than the previous one if one considers +// r to be uniformly distributed in [-pi/4 pi/4]. Again, +// +// sinl(Arg) = (-1)^i_0 * sinl(r + c) if i_1 = 0 +// = (-1)^i_0 * cosl(r + c) if i_1 = 1. +// +// Because |r| is now larger, we need one extra term in the +// correction. sinl(Arg) can be accurately approximated by +// +// sinl(Arg) = (-1)^i_0 * [sinl(r) + c(1-r^2/2)] if i_1 = 0 +// = (-1)^i_0 * [cosl(r) - c*r*(1 - r^2/6)] i_1 = 1. +// +// Finally, sinl(r) and cosl(r) are approximated by polynomials of +// moderate lengths. +// +// sinl(r) = r + PP_1_hi r^3 + PP_1_lo r^3 + +// PP_2 r^5 + ... + PP_8 r^17 +// +// cosl(r) = 1 + QQ_1 r^2 + QQ_2 r^4 + ... + QQ_8 r^16 +// +// where PP_1_hi is only about 16 bits long and QQ_1 is -1/2. +// The crux in accurate computation is to calculate +// +// r + PP_1_hi r^3 or 1 + QQ_1 r^2 +// +// accurately as two pieces: U_hi and U_lo. The way to achieve this +// is to obtain r_hi as a 10 sig. bit number that approximates r to +// roughly 8 bits or so of accuracy. (One convenient way is +// +// r_hi := frcpa( frcpa( r ) ).) +// +// This way, +// +// r + PP_1_hi r^3 = r + PP_1_hi r_hi^3 + +// PP_1_hi (r^3 - r_hi^3) +// = [r + PP_1_hi r_hi^3] + +// [PP_1_hi (r - r_hi) +// (r^2 + r_hi r + r_hi^2) ] +// = U_hi + U_lo +// +// Since r_hi is only 10 bit long and PP_1_hi is only 16 bit long, +// PP_1_hi * r_hi^3 is only at most 46 bit long and thus computed +// exactly. Furthermore, r and PP_1_hi r_hi^3 are of opposite sign +// and that there is no more than 8 bit shift off between r and +// PP_1_hi * r_hi^3. Hence the sum, U_hi, is representable and thus +// calculated without any error. Finally, the fact that +// +// |U_lo| <= 2^(-8) |U_hi| +// +// says that U_hi + U_lo is approximating r + PP_1_hi r^3 to roughly +// 8 extra bits of accuracy. +// +// Similarly, +// +// 1 + QQ_1 r^2 = [1 + QQ_1 r_hi^2] + +// [QQ_1 (r - r_hi)(r + r_hi)] +// = U_hi + U_lo. +// +// Summarizing, we calculate r_hi = frcpa( frcpa( r ) ). +// +// If i_1 = 0, then +// +// U_hi := r + PP_1_hi * r_hi^3 +// U_lo := PP_1_hi * (r - r_hi) * (r^2 + r*r_hi + r_hi^2) +// poly := PP_1_lo r^3 + PP_2 r^5 + ... + PP_8 r^17 +// correction := c * ( 1 + C_1 r^2 ) +// +// Else ...i_1 = 1 +// +// U_hi := 1 + QQ_1 * r_hi * r_hi +// U_lo := QQ_1 * (r - r_hi) * (r + r_hi) +// poly := QQ_2 * r^4 + QQ_3 * r^6 + ... + QQ_8 r^16 +// correction := -c * r * (1 + S_1 * r^2) +// +// End +// +// Finally, +// +// V := poly + ( U_lo + correction ) +// +// / U_hi + V if i_0 = 0 +// result := | +// \ (-U_hi) - V if i_0 = 1 +// +// It is important that in the last step, negation of U_hi is +// performed prior to the subtraction which is to be performed in +// the user-set rounding mode. +// +// +// Algorithmic Description +// ======================= +// +// The argument reduction algorithm is tightly integrated into FSIN +// and FCOS which share the same code.

Note that SAFE not set (false) does not mean +// that overflow/underflow will occur; only the setting of SAFE +// guarantees the opposite. +// +// **** High Level Overview **** +// +// The method consists of three cases. +// +// If |X| < Tiny use case exp_tiny; +// else if |X| < 2^(-6) use case exp_small; +// else use case exp_regular; +// +// Case exp_tiny: +// +// 1 + X can be used to approximate exp(X) +// X + X^2/2 can be used to approximate exp(X) - 1 +// +// Case exp_small: +// +// Here, exp(X) and exp(X) - 1 can all be +// approximated by a relatively simple polynomial. +// +// This polynomial resembles the truncated Taylor series +// +// exp(w) = 1 + w + w^2/2! + w^3/3! + ... + w^n/n! +// +// Case exp_regular: +// +// Here we use a table lookup method. The basic idea is that in +// order to compute exp(X), we accurately decompose X into +// +// X = N * log(2)/(2^12) + r, |r| <= log(2)/2^13. +// +// Hence +// +// exp(X) = 2^( N / 2^12 ) * exp(r). +// +// The value 2^( N / 2^12 ) is obtained by simple combinations +// of values calculated beforehand and stored in table; exp(r) +// is approximated by a short polynomial because |r| is small. +// +// We elaborate this method in 4 steps. +// +// Step 1: Reduction +// +// The value 2^12/log(2) is stored as a double-extended number +// L_Inv. +// +// N := round_to_nearest_integer( X * L_Inv ) +// +// The value log(2)/2^12 is stored as two numbers L_hi and L_lo so +// that r can be computed accurately via +// +// r := (X - N*L_hi) - N*L_lo +// +// We pick L_hi such that N*L_hi is representable in 64 sig. bits +// and thus the FMA X - N*L_hi is error free. So r is the +// 1 rounding error from an exact reduction with respect to +// +// L_hi + L_lo. +// +// In particular, L_hi has 30 significant bit and can be stored +// as a double-precision number; L_lo has 64 significant bits and +// stored as a double-extended number. +// +// Step 2: Approximation +// +// exp(r) - 1 is approximated by a short polynomial of the form +// +// r + A_1 r^2 + A_2 r^3 + A_3 r^4 . +// +// Step 3: Composition from Table Values +// +// The value 2^( N / 2^12 ) can be composed from a couple of tables +// of precalculated values. First, express N as three integers +// K, M_1, and M_2 as +// +// N = K * 2^12 + M_1 * 2^6 + M_2 +// +// Where 0 <= M_1, M_2 < 2^6; and K can be positive or negative. +// When N is represented in 2's complement, M_2 is simply the 6 +// lsb's, M_1 is the next 6, and K is simply N shifted right +// arithmetically (sign extended) by 12 bits. +// +// Now, 2^( N / 2^12 ) is simply +// +// 2^K * 2^( M_1 / 2^6 ) * 2^( M_2 / 2^12 ) +// +// Clearly, 2^K needs no tabulation. The other two values are less +// trivial because if we store each accurately to more than working +// precision, than its product is too expensive to calculate. We +// use the following method. +// +// Define two mathematical values, delta_1 and delta_2, implicitly +// such that +// +// T_1 = exp( [M_1 log(2)/2^6] - delta_1 ) +// T_2 = exp( [M_2 log(2)/2^12] - delta_2 ) +// +// are representable as 24 significant bits. To illustrate the idea, +// we show how we define delta_1: +// +// T_1 := round_to_24_bits( exp( M_1 log(2)/2^6 ) ) +// delta_1 = (M_1 log(2)/2^6) - log( T_1 ) +// +// The last equality means mathematical equality. We then tabulate +// +// W_1 := exp(delta_1) - 1 +// W_2 := exp(delta_2) - 1 +// +// Both in double precision. +// +// From the tabulated values T_1, T_2, W_1, W_2, we compose the values +// T and W via +// +// T := T_1 * T_2 ...exactly +// W := W_1 + (1 + W_1)*W_2 +// +// W approximates exp( delta ) - 1 where delta = delta_1 + delta_2. +// The mathematical product of T and (W+1) is an accurate representation +// of 2^(M_1/2^6) * 2^(M_2/2^12). +// +// Step 4. Reconstruction +// +// Finally, we can reconstruct exp(X), exp(X) - 1. +// Because +// +// X = K * log(2) + (M_1*log(2)/2^6 - delta_1) +// + (M_2*log(2)/2^12 - delta_2) +// + delta_1 + delta_2 + r ...accurately +// We have +// +// exp(X) ~=~ 2^K * ( T + T*[exp(delta_1+delta_2+r) - 1] ) +// ~=~ 2^K * ( T + T*[exp(delta + r) - 1] ) +// ~=~ 2^K * ( T + T*[(exp(delta)-1) +// + exp(delta)*(exp(r)-1)] ) +// ~=~ 2^K * ( T + T*( W + (1+W)*poly(r) ) ) +// ~=~ 2^K * ( Y_hi + Y_lo ) +// +// where Y_hi = T and Y_lo = T*(W + (1+W)*poly(r)) +// +// For exp(X)-1, we have +// +// exp(X)-1 ~=~ 2^K * ( Y_hi + Y_lo ) - 1 +// ~=~ 2^K * ( Y_hi + Y_lo - 2^(-K) ) +// +// and we combine Y_hi + Y_lo - 2^(-N) into the form of two +// numbers Y_hi + Y_lo carefully. +// +// **** Algorithm Details **** +// +// A careful algorithm must be used to realize the mathematical ideas +// accurately.

The basic idea is that in +// order to compute exp(X), we accurately decompose X into +// +// X = N * log(2)/(2^12) + r, |r| <= log(2)/2^13. +// +// Hence +// +// exp(X) = 2^( N / 2^12 ) * exp(r). +// +// The value 2^( N / 2^12 ) is obtained by simple combinations +// of values calculated beforehand and stored in table; exp(r) +// is approximated by a short polynomial because |r| is small. +// +// We elaborate this method in 4 steps. +// +// Step 1: Reduction +// +// The value 2^12/log(2) is stored as a double-extended number +// L_Inv. +// +// N := round_to_nearest_integer( X * L_Inv ) +// +// The value log(2)/2^12 is stored as two numbers L_hi and L_lo so +// that r can be computed accurately via +// +// r := (X - N*L_hi) - N*L_lo +// +// We pick L_hi such that N*L_hi is representable in 64 sig. bits +// and thus the FMA X - N*L_hi is error free. So r is the +// 1 rounding error from an exact reduction with respect to +// +// L_hi + L_lo. +// +// In particular, L_hi has 30 significant bit and can be stored +// as a double-precision number; L_lo has 64 significant bits and +// stored as a double-extended number. +// +// Step 2: Approximation +// +// exp(r) - 1 is approximated by a short polynomial of the form +// +// r + A_1 r^2 + A_2 r^3 + A_3 r^4 . +// +// Step 3: Composition from Table Values +// +// The value 2^( N / 2^12 ) can be composed from a couple of tables +// of precalculated values. First, express N as three integers +// K, M_1, and M_2 as +// +// N = K * 2^12 + M_1 * 2^6 + M_2 +// +// Where 0 <= M_1, M_2 < 2^6; and K can be positive or negative. +// When N is represented in 2's complement, M_2 is simply the 6 +// lsb's, M_1 is the next 6, and K is simply N shifted right +// arithmetically (sign extended) by 12 bits. +// +// Now, 2^( N / 2^12 ) is simply +// +// 2^K * 2^( M_1 / 2^6 ) * 2^( M_2 / 2^12 ) +// +// Clearly, 2^K needs no tabulation. The other two values are less +// trivial because if we store each accurately to more than working +// precision, than its product is too expensive to calculate. We +// use the following method. +// +// Define two mathematical values, delta_1 and delta_2, implicitly +// such that +// +// T_1 = exp( [M_1 log(2)/2^6] - delta_1 ) +// T_2 = exp( [M_2 log(2)/2^12] - delta_2 ) +// +// are representable as 24 significant bits. To illustrate the idea, +// we show how we define delta_1: +// +// T_1 := round_to_24_bits( exp( M_1 log(2)/2^6 ) ) +// delta_1 = (M_1 log(2)/2^6) - log( T_1 ) +// +// The last equality means mathematical equality. We then tabulate +// +// W_1 := exp(delta_1) - 1 +// W_2 := exp(delta_2) - 1 +// +// Both in double precision. +// +// From the tabulated values T_1, T_2, W_1, W_2, we compose the values +// T and W via +// +// T := T_1 * T_2 ...exactly +// W := W_1 + (1 + W_1)*W_2 +// +// W approximates exp( delta ) - 1 where delta = delta_1 + delta_2. +// The mathematical product of T and (W+1) is an accurate representation +// of 2^(M_1/2^6) * 2^(M_2/2^12). +// +// Step 4. Reconstruction +// +// Finally, we can reconstruct exp(X), exp(X) - 1. +// Because +// +// X = K * log(2) + (M_1*log(2)/2^6 - delta_1) +// + (M_2*log(2)/2^12 - delta_2) +// + delta_1 + delta_2 + r ...accurately +// We have +// +// exp(X) ~=~ 2^K * ( T + T*[exp(delta_1+delta_2+r) - 1] ) +// ~=~ 2^K * ( T + T*[exp(delta + r) - 1] ) +// ~=~ 2^K * ( T + T*[(exp(delta)-1) +// + exp(delta)*(exp(r)-1)] ) +// ~=~ 2^K * ( T + T*( W + (1+W)*poly(r) ) ) +// ~=~ 2^K * ( Y_hi + Y_lo ) +// +// where Y_hi = T and Y_lo = T*(W + (1+W)*poly(r)) +// +// For exp(X)-1, we have +// +// exp(X)-1 ~=~ 2^K * ( Y_hi + Y_lo ) - 1 +// ~=~ 2^K * ( Y_hi + Y_lo - 2^(-K) ) +// +// and we combine Y_hi + Y_lo - 2^(-N) into the form of two +// numbers Y_hi + Y_lo carefully. +// +// **** Algorithm Details **** +// +// A careful algorithm must be used to realize the mathematical ideas +// accurately.

This polynomial resembles the truncated Taylor +// series W - W^/2 + W^3/3 - ... +// +// Case log_regular: +// +// Here we use a table lookup method. The basic idea is that in +// order to compute logl(Arg) = log1pl (Arg-1) for an argument Arg in [1,2), +// we construct a value G such that G*Arg is close to 1 and that +// logl(1/G) is obtainable easily from a table of values calculated +// beforehand. Thus +// +// logl(Arg) = logl(1/G) + logl(G*Arg) +// = logl(1/G) + logl(1 + (G*Arg - 1)) +// +// Because |G*Arg - 1| is small, the second term on the right hand +// side can be approximated by a short polynomial. We elaborate +// this method in four steps. +// +// Step 0: Initialization +// +// We need to calculate logl( X+1 ). Obtain N, S_hi such that +// +// X+1 = 2^N * ( S_hi + S_lo ) exactly +// +// where S_hi in [1,2) and S_lo is a correction to S_hi in the sense +// that |S_lo| <= ulp(S_hi). +// +// Step 1: Argument Reduction +// +// Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate +// +// G := G_1 * G_2 * G_3 +// r := (G * S_hi - 1) + G * S_lo +// +// These G_j's have the property that the product is exactly +// representable and that |r| < 2^(-12) as a result. +// +// Step 2: Approximation +// +// +// logl(1 + r) is approximated by a short polynomial poly(r). +// +// Step 3: Reconstruction +// +// +// Finally, log1pl( X ) = logl( X+1 ) is given by +// +// logl( X+1 ) = logl( 2^N * (S_hi + S_lo) ) +// ~=~ N*logl(2) + logl(1/G) + logl(1 + r) +// ~=~ N*logl(2) + logl(1/G) + poly(r). +// +// **** Algorithm **** +// +// Case log1p_small: +// +// Although log1pl(X) is basically X, we would like to preserve the inexactness +// nature as well as consistent behavior under different rounding modes. +// We can do this by computing the result as +// +// log1pl(X) = X - X*X +// +// +// Case log_near1: +// +// Here we compute a simple polynomial.

Now, given +// +// Arg = N pi/2 + alpha, |alpha| <= pi/4, +// +// basic mathematical relationship shows that +// +// tan( Arg ) = tan( alpha ) if N is even; +// = -cot( alpha ) otherwise. +// +// The value of alpha is obtained by argument reduction and +// represented by two working precision numbers r and c where +// +// alpha = r + c accurately. +// +// The reduction method is described in a previous write up. +// The argument reduction scheme identifies 4 cases. For Cases 2 +// and 4, because |alpha| is small, tan(r+c) and -cot(r+c) can be +// computed very easily by 2 or 3 terms of the Taylor series +// expansion as follows: +// +// Case 2: +// ------- +// +// tan(r + c) = r + c + r^3/3 ...accurately +// -cot(r + c) = -1/(r+c) + r/3 ...accurately +// +// Case 4: +// ------- +// +// tan(r + c) = r + c + r^3/3 + 2r^5/15 ...accurately +// -cot(r + c) = -1/(r+c) + r/3 + r^3/45 ...accurately +// +// +// The only cases left are Cases 1 and 3 of the argument reduction +// procedure. These two cases will be merged since after the +// argument is reduced in either cases, we have the reduced argument +// represented as r + c and that the magnitude |r + c| is not small +// enough to allow the usage of a very short approximation. +// +// The greatest challenge of this task is that the second terms of +// the Taylor series for tan(r) and -cot(r) +// +// r + r^3/3 + 2 r^5/15 + ... +// +// and +// +// -1/r + r/3 + r^3/45 + ... +// +// are not very small when |r| is close to pi/4 and the rounding +// errors will be a concern if simple polynomial accumulation is +// used. When |r| < 2^(-2), however, the second terms will be small +// enough (5 bits or so of right shift) that a normal Horner +// recurrence suffices. Hence there are two cases that we consider +// in the accurate computation of tan(r) and cot(r), |r| <= pi/4. +// +// Case small_r: |r| < 2^(-2) +// -------------------------- +// +// Since Arg = N pi/4 + r + c accurately, we have +// +// tan(Arg) = tan(r+c) for N even, +// = -cot(r+c) otherwise. +// +// Here for this case, both tan(r) and -cot(r) can be approximated +// by simple polynomials: +// +// tan(r) = r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19 +// -cot(r) = -1/r + Q1_1 r + Q1_2 r^3 + ... + Q1_7 r^13 +// +// accurately. Since |r| is relatively small, tan(r+c) and +// -cot(r+c) can be accurately approximated by replacing r with +// r+c only in the first two terms of the corresponding polynomials. +// +// Note that P1_1 (and Q1_1 for that matter) approximates 1/3 to +// almost 64 sig. bits, thus +// +// P1_1 (r+c)^3 = P1_1 r^3 + c * r^2 accurately. +// +// Hence, +// +// tan(r+c) = r + P1_1 r^3 + P1_2 r^5 + ... + P1_9 r^19 +// + c*(1 + r^2) +// +// -cot(r+c) = -1/(r+c) + Q1_1 r + Q1_2 r^3 + ... + Q1_7 r^13 +// + Q1_1*c +// +// +// Case normal_r: 2^(-2) <= |r| <= pi/4 +// ------------------------------------ +// +// This case is more likely than the previous one if one considers +// r to be uniformly distributed in [-pi/4 pi/4]. +// +// The required calculation is either +// +// tan(r + c) = tan(r) + correction, or +// -cot(r + c) = -cot(r) + correction. +// +// Specifically, +// +// tan(r + c) = tan(r) + c tan'(r) + O(c^2) +// = tan(r) + c sec^2(r) + O(c^2) +// = tan(r) + c SEC_sq ...accurately +// as long as SEC_sq approximates sec^2(r) +// to, say, 5 bits or so. +// +// Similarly, +// +// -cot(r + c) = -cot(r) - c cot'(r) + O(c^2) +// = -cot(r) + c csc^2(r) + O(c^2) +// = -cot(r) + c CSC_sq ...accurately +// as long as CSC_sq approximates csc^2(r) +// to, say, 5 bits or so. +// +// We therefore concentrate on accurately calculating tan(r) and +// cot(r) for a working-precision number r, |r| <= pi/4 to within +// 0.1% or so. +// +// We will employ a table-driven approach.

For that we subdivide interval +// [2; OVERFLOW_BOUNDARY] into intervals [16*n; 16*(n+1)] and +// approximate GAMMA(x) by polynomial of 22th degree on each +// [16*n; 16*n+1], recursive formula is used to expand GAMMA(x) +// to [16*n; 16*n+1]. In other words we need to find n, i and r +// such that x = 16 * n + i + r where n and i are integer numbers +// and r is fractional part of x.

For that we subdivide interval +// [2; OVERFLOW_BOUNDARY] into intervals [8*n; 8*(n+1)] and +// approximate GAMMA(x) by polynomial of 22th degree on each +// [8*n; 8*n+1], recursive formula is used to expand GAMMA(x) +// to [8*n; 8*n+1].

When HPPA switched to NPTL, we +dropped the use of ldcw, and switched to the kernel helper routine for +compare-and-swap. This allowed HPPA to use the 4-word 16-byte aligned +lock words, and alignment words to store the additional pthread_cond_t +data.

In this case, the first +four words were set to one, and must be cleared before any NPTL code +used these words. + +We didn't want to use LDCW, because it continues to be a source of bugs +when applications memset pthread_cond_t to all zeroes by accident. This +works on all other architectures where lock words are unlocked at zero. +Remember that because of the semantics of LDCW, a locked word is set to +zero, and an unlocked word is set to 1. + +Instead we used atomic_compare_and_exchange_val_acq, but we couldn't use +this on any of the pthread_cond_t words, otherwise it might interfere +with the current operation of the structure.

The first thread to come upon a +pthread_cond_t with a 1 in the __initializer field, will +compare-and-swap the value, placing a 2 there which will cause all other +threads using the same pthread_cond_t to wait for the completion of the +initialization. Lastly, we use a store (with memory barrier) to change +__initializer from 2 to 0.
