2017-10-11Run libm long double tests for long double = double.Joseph Myers
All interfaces in the glibc API ought to be covered by the testsuite, even where they alias other interfaces. This patch arranges for libm tests to be run for long double when it aliases double; previously those tests were run only for the floating-point types with distinct formats. The long double tests are made to use the double ulps values in this case, as having a separate duplicate set of ulps for them seems unnecessary; to accommodate that, the test-<type>.h headers now specify the macro indexing into the ulps array explicitly instead of having it computed from PREFIX. Nothing special is done about vector function tests. None are supported for any long double = double platforms, and supporting vector functions for a type alias such as _Float32 would not simply fall out of adding the scalar aliases for that type - it would require vector function wrappers like those for *_finite (or, better, a new GCC feature to allow specifying the asm name for vector functions independently of that for scalar ones, as previously discussed), so it seems reasonable to require the sysdeps makefile setting of libmvec-tests to be updated if any such tests are to be run for type aliases. Tested for x86_64 and arm. * math/Makefile (test-types-basic): New variable. (test-types): Likewise. (libm-test-support): Use $(test-types) instead of $(types). (libm-tests-base-normal): Likewise.

2016-12-20Replace use of snprintf with strfrom in libm testsGabriel F. T. Gomes
In order to support float128 tests, the calls to snprintf, which does not support the type __float128, are replaced with calls to strfrom{f,d,l}. Tested for powerpc64le, s390, and x64_64.
2016-10-28Add SNAN, SNANF, SNANL macros.Joseph Myers
TS 18661-1 defines SNAN macros for signaling NaN values, suitable for use in static initializers. This patch adds them to glibc's <math.h> (provided you are building with GCC 3.3 or later; no attempt is made to provide any kind of nonconforming fallback for older compilers without the __builtin_nans functions). Tested for x86_64 and x86. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT) && __GNUC_PREREQ (3, 3)] (SNANF): New macro. [__GLIBC_USE (IEC_60559_BFP_EXT) && __GNUC_PREREQ (3, 3)] (SNAN): Likewise. [__GLIBC_USE (IEC_60559_BFP_EXT) && __GNUC_PREREQ (3, 3)] (SNANL): Likewise. * manual/arith.texi (Infinity and NaN): Document SNANF, SNAN and SNANL. * math/test-double.h (snan_value_MACRO): New macro. * math/test-float.h (snan_value_MACRO): Likewise. * math/test-ldouble.h (snan_value_MACRO): Likewise. * math/libm-test.inc (issignaling_test_data): Add tests of snan_value_MACRO.
2016-06-08Remove CHOOSE() macro from libm-tests.incPaul E. Murphy
Use gen-libm-test.pl to generate a list of macros mapping to libm-test-ulps.h as this simplifies adding new types without having to modify a growing number of static headers each time a type is added. This also removes the final usage of the TEST_(DOUBLE|FLOAT|LDOUBLE) macros. Thus, they too are removed.
2016-05-27Replace M_PI2l with lit_pi_2_d in libm-test.incPaul E. Murphy
This is useful in situations where the long double type is less precise than the type under test. This adds a new wrapper macro LITM(x) to each type to append the proper suffix onto macro constants found in math.h.
2016-05-27Begin refactor of libm-test.incPaul E. Murphy
Attempt to creatively redefine the macros to choose tests based on the format being tested, not the type. Note, TS 18661 does not define any printf modifiers, so we need to be a little more verbose about constructing strings to output.

2015-10-28Use C11 CMPLX* macros in libm tests.Joseph Myers
libm-test.inc has a macro BUILD_COMPLEX to construct a complex number with given real and imaginary parts while allowing properly for signed zeroes, infinities and NaNs (which don't work properly with a simple real + I * imag, in the absence of compiler support for imaginary types), using assignment to __real__ and __imag__ parts of the number. C11 defines CMPLX* macros for this purpose, which GCC 4.7 and above provide suitable built-in functions for. This patch redefines BUILD_COMPLEX in terms of the standard macros. Tested for x86_64 and x86. * math/libm-test.inc (BUILD_COMPLEX): Remove macro. * math/test-double.h (BUILD_COMPLEX): New macro. * math/test-float.h (BUILD_COMPLEX): Likewise. * math/test-ldouble.h (BUILD_COMPLEX): Likewise.
2015-06-24Refactor libm tests.Joseph Myers
This patch refactors the libm tests using libm-test.inc to reduce the level of duplicate definitions. New headers are created for the definitions shared by tests for a particular type; by tests of inline functions; by tests of non-inline functions; by scalar tests; and by vector tests. The unused MATHCONST macro is removed. A new macro VEC_LEN is added to the vector headers to allow the macros defining wrappers for vector functions to be defined once, instead of six times each (differing only in vector length) as before. There is still scope for further refactoring, but this seems a useful start.
