This file is processed by a perl script. The resulting file has to be included by a master file that defines: Macros: FUNC(function): converts general function name (like cos) to name with correct suffix (e.g. cosl or cosf) MATHCONST(x): like FUNC but for constants (e.g convert 0.0 to 0.0L) FLOAT: floating point type to test - TEST_MSG: informal message to be displayed CHOOSE(Clongdouble,Cdouble,Cfloat,Cinlinelongdouble,Cinlinedouble,Cinlinefloat): chooses one of the parameters as delta for testing equality PRINTF_EXPR Floating point conversion specification to print a variable of type FLOAT with printf. PRINTF_EXPR just contains the specifier, not the percent and width arguments, e.g. "f". PRINTF_XEXPR Like PRINTF_EXPR, but print in hexadecimal format. PRINTF_NEXPR Like PRINTF_EXPR, but print nice. */ /* This testsuite has currently tests for: acos, acosh, asin, asinh, atan, atan2, atanh, cbrt, ceil, copysign, cos, cosh, erf, erfc, exp, exp10, exp2, expm1, fabs, fdim, floor, fma, fmax, fmin, fmod, fpclassify, frexp, gamma, hypot, ilogb, isfinite, isinf, isnan, isnormal, isless, islessequal, isgreater, isgreaterequal, islessgreater, isunordered, j0, j1, jn, ldexp, lgamma, log, log10, log1p, log2, logb, modf, nearbyint, nextafter, pow, remainder, remquo, rint, lrint, llrint, round, lround, llround, scalb, scalbn, scalbln, signbit, sin, sincos, sinh, sqrt, tan, tanh, tgamma, trunc, y0, y1, yn, significand and for the following complex math functions: cabs, cacos, cacosh, carg, casin, casinh, catan, catanh, ccos, ccosh, cexp, clog, cpow, cproj, csin, csinh, csqrt, ctan, ctanh. At the moment the following functions aren't tested: drem, nan Parameter handling is primitive in the moment: --verbose=[0..3] for different levels of output: 0: only error count 1: basic report on failed tests (default) 2: full report on all tests -v for full output (equals --verbose=3) -u for generation of an ULPs file */ /* "Philosophy": This suite tests some aspects of the correct implementation of mathematical functions in libm. Some simple, specific parameters are tested for correctness but there's no exhaustive testing. Handling of specific inputs (e.g. infinity, not-a-number) is also tested. Correct handling of exceptions is checked against. These implemented tests should check all cases that are specified in ISO C99. Exception testing: At the moment only divide-by-zero and invalid exceptions are tested. Overflow/underflow and inexact exceptions aren't checked at the moment. NaN values: There exist signalling and quiet NaNs. This implementation only uses quiet NaN as parameter but does not differenciate between the two kinds of NaNs as result. Inline functions: Inlining functions should give an improvement in speed - but not in precission. The inlined functions return reasonable values for a reasonable range of input values. The result is not necessarily correct for all values and exceptions are not correctly raised in all cases. Problematic input and return values are infinity, not-a-number and minus zero. This suite therefore does not check these specific inputs and the exception handling for inlined mathematical functions - just the "reasonable" values are checked. Beware: The tests might fail for any of the following reasons: - Tests are wrong - Functions are wrong - Floating Point Unit not working properly - Compiler has errors With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error. To Do: All parameter should be numbers that can be represented as exact floating point values. Currently some values cannot be represented exactly and therefore the result is not the expected result. For this we will use 36 digits so that numbers can be represented exactly. */ #ifndef _GNU_SOURCE # define _GNU_SOURCE #endif #include "libm-test-ulps.h" #include #include #include #include #include #include #include #include #include #include /* Possible exceptions */ #define NO_EXCEPTION 0x0 #define INVALID_EXCEPTION 0x1 #define DIVIDE_BY_ZERO_EXCEPTION 0x2 /* The next flags signals that those exceptions are allowed but not required. */ #define INVALID_EXCEPTION_OK 0x4 #define DIVIDE_BY_ZERO_EXCEPTION_OK 0x8 #define EXCEPTIONS_OK INVALID_EXCEPTION_OK+DIVIDE_BY_ZERO_EXCEPTION_OK /* Some special test flags, passed togther with exceptions. */ #define IGNORE_ZERO_INF_SIGN 0x10 /* Various constants (we must supply them precalculated for accuracy). */ #define M_PI_6l .52359877559829887307710723054658383L #define M_E2l 7.389056098930650227230427460575008L #define M_E3l 20.085536923187667740928529654581719L #define M_2_SQRT_PIl 3.5449077018110320545963349666822903L /* 2 sqrt (M_PIl) */ #define M_SQRT_PIl 1.7724538509055160272981674833411451L /* sqrt (M_PIl) */ #define M_LOG_SQRT_PIl 0.57236494292470008707171367567652933L /* log(sqrt(M_PIl)) */ #define M_LOG_2_SQRT_PIl 1.265512123484645396488945797134706L /* log(2*sqrt(M_PIl)) */ #define M_PI_34l (M_PIl - M_PI_4l) /* 3*pi/4 */ #define M_PI_34_LOG10El (M_PIl - M_PI_4l) * M_LOG10El #define M_PI2_LOG10El M_PI_2l * M_LOG10El #define M_PI4_LOG10El M_PI_4l * M_LOG10El #define M_PI_LOG10El M_PIl * M_LOG10El #define M_SQRT_2_2 0.70710678118654752440084436210484903L /* sqrt (2) / 2 */ static FILE *ulps_file; /* File to document difference. */ static int output_ulps; /* Should ulps printed? */ static int noErrors; /* number of errors */ static int noTests; /* number of tests (without testing exceptions) */ static int noExcTests; /* number of tests for exception flags */ static int noXFails; /* number of expected failures. */ static int noXPasses; /* number of unexpected passes. */ static int verbose; static int output_max_error; /* Should the maximal errors printed? */ static int output_points; /* Should the single function results printed? */ static int ignore_max_ulp; /* Should we ignore max_ulp? */ static FLOAT minus_zero, plus_zero; static FLOAT plus_infty, minus_infty, nan_value, max_value, min_value; static FLOAT max_error, real_max_error, imag_max_error; #define BUILD_COMPLEX(real, imag) \ ({ __complex__ FLOAT __retval; \ __real__ __retval = (real); \ __imag__ __retval = (imag); \ __retval; }) #define BUILD_COMPLEX_INT(real, imag) \ ({ __complex__ int __retval; \ __real__ __retval = (real); \ __imag__ __retval = (imag); \ __retval; }) #define MANT_DIG CHOOSE ((LDBL_MANT_DIG-1), (DBL_MANT_DIG-1), (FLT_MANT_DIG-1), \ (LDBL_MANT_DIG-1), (DBL_MANT_DIG-1), (FLT_MANT_DIG-1)) static void init_max_error (void) { max_error = 0; real_max_error = 0; imag_max_error = 0; feclearexcept (FE_ALL_EXCEPT); } static void set_max_error (FLOAT current, FLOAT *curr_max_error) { if (current > *curr_max_error) *curr_max_error = current; } /* Should the message print to screen?
