From 1f4dafa3ea24df63a6550dbdbbe8769caa7a9fc3 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 28 Oct 2015 21:42:52 +0000 Subject: Use C11 *_TRUE_MIN macros where applicable. C11 defines standard macros *_TRUE_MIN for the least positive subnormal value of a type. Now that we build with -std=gnu11, we can use these macros in glibc. This patch replaces previous uses of the GCC predefines __*_DENORM_MIN__ (used in to define *_TRUE_MIN), as well as *_DENORM_MIN references in comments. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). Also tested for powerpc that installed stripped shared libraries are unchanged by the patch. * math/libm-test.inc (min_subnorm_value): Use LDBL_TRUE_MIN, DBL_TRUE_MIN and FLT_TRUE_MIN instead of __LDBL_DENORM_MIN__, __DBL_DENORM_MIN__ and __FLT_DENORM_MIN__. * sysdeps/ieee754/dbl-64/s_fma.c (__fma): Refer to DBL_TRUE_MIN instead of DBL_DENORM_MIN in comment. * sysdeps/ieee754/ldbl-128/s_fmal.c (__fmal): Refer to LDBL_TRUE_MIN instead of LDBL_DENORM_MIN in comment. * sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c: Include . (__nextafterl): Use LDBL_TRUE_MIN instead of __LDBL_DENORM_MIN__. * sysdeps/ieee754/ldbl-96/s_fmal.c (__fmal): Refer to LDBL_TRUE_MIN instead of LDBL_DENORM_MIN in comment. --- math/libm-test.inc | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'math') diff --git a/math/libm-test.inc b/math/libm-test.inc index 6cce5fcae4..631b205503 100644 --- a/math/libm-test.inc +++ b/math/libm-test.inc @@ -315,12 +315,12 @@ static int ignore_max_ulp; /* Should we ignore max_ulp? */ LDBL_MAX, DBL_MAX, FLT_MAX) #define min_value CHOOSE (LDBL_MIN, DBL_MIN, FLT_MIN, \ LDBL_MIN, DBL_MIN, FLT_MIN) -#define min_subnorm_value CHOOSE (__LDBL_DENORM_MIN__, \ - __DBL_DENORM_MIN__, \ - __FLT_DENORM_MIN__, \ - __LDBL_DENORM_MIN__, \ - __DBL_DENORM_MIN__, \ - __FLT_DENORM_MIN__) +#define min_subnorm_value CHOOSE (LDBL_TRUE_MIN, \ + DBL_TRUE_MIN, \ + FLT_TRUE_MIN, \ + LDBL_TRUE_MIN, \ + DBL_TRUE_MIN, \ + FLT_TRUE_MIN) static FLOAT max_error, real_max_error, imag_max_error; -- cgit v1.2.3
