* Rename header.pot to pot.header.Carlos O'Donell2014-01-083-4/+9
| | | | | | | | | | | The Translation Project has asked us to rename the pot header file `header.pot' to something else. Their scripts automatically look for pot files and the file `header.pot' is not actually a pot file but a header that we use when regenerating `libc.pot.' This commit renames `header.pot' to `pot.header' to avoid causing errors or complicating the TP project scripts.

* PowerPC: remove wrong truncl implementation for PowerPC64Adhemerval Zanella2014-01-084-125/+9
| | | | | | | | | | | | | | | The truncl assembly implementation (sysdeps/powerpc/powerpc64/fpu/s_truncl.S) returns wrong results for some inputs where first double is a exact integer and the precision is determined by second long double. Checking on implementation comments and history, I am very confident the assembly implementation was based on a version before commit 5c68d401698a58cf7da150d9cce769fa6679ba5f that fixes BZ#2423 (Errors in long double (ldbl-128ibm) rounding functions in glibc-2.4). By just removing the implementation and make the build select sysdeps/ieee754/ldbl-128ibm/s_truncl.c instead it fixes tgammal issues regarding wrong result sign.

* Fix ldbl-128ibm expm1l on large arguments (bug 16408).Joseph Myers2014-01-083-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16408, ldbl-128ibm expm1l returning NaN for some large arguments. The basic problem is that the approach of converting the exponent to the form n * log(2) + y, where -0.5 <= y <= 0.5, then computing 2^n * expm1(y) + (2^n - 1) falls over when 2^n overflows (starting slightly before the point where expm1 overflows, when y is negative and n is the least integer for which 2^n overflows). The ldbl-128 code, and the x86/x86_64 code, make expm1l fall back to expl for large positive arguments to avoid this issue. This patch makes the ldbl-128ibm code do the same. (The problem appears for the particular argument in the testsuite because the ldbl-128ibm code also uses an overflow threshold that's for ldbl-128 and is too big for ldbl-128ibm, but the problem described applies for large non-overflowing cases as well, although during the freeze is not a suitable time for making the expm1 tests cover cases close to overflow more thoroughly.) This leaves some code for large positive arguments in expm1l that is now dead. To keep the code for ldbl-128 and ldbl-128ibm similar, and to avoid unnecessary changes during the freeze, the patch doesn't remove it; instead I propose to file a bug in Bugzilla as a reminder that this code (for overflow, including errno setting, and for arguments of +Inf) is no longer needed and should be removed from both those expm1l implementations. Tested powerpc32. * sysdeps/ieee754/ldbl-128ibm/s_expm1l.c (__expm1l): Use __expl for large positive arguments.
* Use separate libc.abilist for MIPS o32 soft float.Joseph Myers2014-01-073-0/+2268
| | | | | | | | | | | | | | | | | | | | Examining MIPS test results showed an ABI test failure that I must have missed in 2.18 testing: hard-float and soft-float o32 no longer have the same set of symbols (because of the __mips_fpu_getcw and __mips_fpu_setcw functions, present for hard-float only, used by fpu_control.h for hard-float MIPS16) and so need separate ABI test baselines (they always were ABI-incompatible - the function-calling interface is different - but previously had the same set of symbols and versions so didn't need separate baselines). Tested for hard-float and soft-float o32. * sysdeps/unix/sysv/linux/mips/mips32/nptl/libc.abilist: Move to .... * sysdeps/unix/sysv/linux/mips/mips32/fpu/nptl/libc.abilist: ... here. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/nptl/libc.abilist: New file.

* Mark more libm tests with xfail-rounding:ldbl-128ibm.Joseph Myers2014-01-073-433/+443
| | | | | | | | | | | | | | | | | | | | | | | This patch marks more libm tests as expected to fail for ldbl-128ibm in non-default rounding modes. Given this, my expm1l fix <https://sourceware.org/ml/libc-alpha/2014-01/msg00135.html> and my libgcc fix <http://gcc.gnu.org/ml/gcc-patches/2014-01/msg00157.html> for spurious overflows, the remaining failures in test-ldouble.out (for powerpc32 hard float) are small ulps, spurious underflow and inexact exceptions (the former probably arising from libgcc bugs though I haven't checked each case; the latter are barely meaningful for this format anyway when basic arithmetic isn't correctly rounding, though most of them are probably GCC bug 59412 which doesn't actually involve long double), missing underflow exceptions from clog, ctan and ctanh (probably one of the known bugs for another function), and logb in round-downward mode (bug 887, though it's really a GCC bug that we're not currently working around). Tested for powerpc32 hard float. * math/auto-libm-test-in: Mark various tests with xfail-rounding:ldbl-128ibm. * math/auto-libm-test-out: Regenerated.
* Fix ldbl-128ibm coshl spurious overflows (bug 16407).Joseph Myers2014-01-073-2/+8
| | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16407, spurious overflows from ldbl-128ibm coshl. The implementation assumed that a high part (reinterpreted as an integer) of the absolute value of the argument of 0x408633ce8fb9f87dLL or more meant overflow, but the actual threshold has high part 0x408633ce8fb9f87eLL (and a negative low part). The patch adjusts the threshold accordingly. sinhl probably has the same issue, but I didn't get that far in adding tests of special cases (such as just below and above overflow) before the freeze and during the freeze is not a suitable time to add them (as they'd require ulps to be regenerated again), so I'm not changing that function for now; when I add more tests of special cases, we'll discover whether sinhl indeed has this problem. Tested powerpc32. * sysdeps/ieee754/ldbl-128ibm/e_coshl.c (__ieee754_coshl): Increase overflow threshold.

| | | | | | | | | | | | | | This patch fixes bug 16400, spurious underflow exceptions for ldbl-128 / ldbl-128ibm lgammal with small positive arguments, by just using -__logl (x) as the result in the problem cases (similar to the previous fix for problems with small negative arguments). Tested powerpc32, and also tested on mips64 that this does not require ulps regeneration for the ldbl-128 case. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgammal_r): Return -__logl (x) for small positive arguments without evaluating a polynomial.

| | | | | | | | | | | | This addresses a long standing collision between userspace headers and kernel headers only on ia64 systems. All other types have a __ prefix in the ptrace headers except these two. Let's finally namespace these. Verified that at least strace still builds after this change, as well as after deleting all the struct hacks it has specifically for ia64.

* ia64: fix build failure after async tls updatesMike Frysinger2014-01-042-4/+11
| | | | | | | | | | The recent commit 7f507ee17aee720fa423fa38502bc3caa0dd03d7 added a new local variable "offset" to tls_get_addr_tail. This conflicts with the ia64 code which also declares an offset code inline in this func.

* Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390).Joseph Myers2014-01-033-1/+8
| | | | | | | | | | | This patch fixes bug 16390, incorrect signs of zero results from ldbl-128ibm atan2l, soft-float only. The problem is a longstanding GCC bug with fabsl not being correct for signed zero for soft float, and the fix is using -fno-builtin-fabsl as a workaround, as already done for various other source files. Tested powerpc-nofpu. * sysdeps/powerpc/nofpu/Makefile [$(subdir) = math] (CFLAGS-e_atan2l.c): Use -fno-builtin-fabsl.

* Mark various libm tests with xfail-rounding:ldbl-128ibm.Joseph Myers2014-01-033-1744/+1759
| | | | | | | | | | | | | | | | | | | | This patch marks various libm tests with xfail-rounding:ldbl-128ibm, where the failures appear to relate to GCC bug 59666 (bad libgcc handling of directed rounding), so as to allow clean libm-test-ulps regeneration without needing to edit out large ulps for various functions manually. Note that this only deals with the cases problematic for ulps regeneration. There are plenty of test failures left that do not affect ulps regeneration - results that are infinities or NaNs but should be finite, or vice versa, and missing and spurious exceptions - which should also be resolved during the release testing period. Tested for powerpc32 (hard float). * math/auto-libm-test-in: Mark various tests with xfail-rounding:ldbl-128ibm. * math/auto-libm-test-out: Regenerated.
* Fix ldbl-128ibm logl inaccuracy (bug 16386).Joseph Myers2014-01-023-1/+14
| | | | | | | | | | | | This patch fixes bug 16386, ldbl-128ibm logl inaccuracy (with consequent inaccuracy for lgammal) for arguments where the high double is subnormal, which showed up while attempting to regenerate ulps for powerpc-nofpu for 2.19. The problem here is logic failing to allow for subnormals when calculating the exponent of the argument.

There were two separate problems, use of __log1p instead of __log1pl and an insufficiently accurate constant value for log 2 (which this patch replaces by use of M_LN2l), each of which could cause substantial inaccuracy in affected cases. Tested for powerpc-nofpu. * sysdeps/ieee754/ldbl-128ibm/e_acoshl.c (ln2): Initialize with M_LN2l. (__ieee754_acoshl): Use __log1pl not __log1p.
