From 963394a22b38c4ec92b6875a6c06d3b15d5c0d21 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Sun, 20 Nov 2016 20:46:30 -0500 Subject: [PATCH] Allow direct use of math_ldbl.h in testsuite. A few 'long double'-related tests include math_private.h just for their variety of math_ldbl.h, which contains macros for assembling and disassembling the binary representation of 'long double'. math_ldbl.h insists on being included from math_private.h, but if we relax this restriction (and fix some portability sloppiness) we can use it directly and not have to expose all of math_private.h to the testsuite. * sysdeps/generic/math_private.h: Use __BIG_ENDIAN and __LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN. * sysdeps/generic/math_ldbl.h * sysdeps/ia64/fpu/math_ldbl.h * sysdeps/ieee754/ldbl-128/math_ldbl.h * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h * sysdeps/ieee754/ldbl-96/math_ldbl.h * sysdeps/powerpc/fpu/math_ldbl.h * sysdeps/x86_64/fpu/math_ldbl.h: Allow direct inclusion. Use uintNN_t instead of u_intNN_t. Use __BIG_ENDIAN and __LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN. Include endian.h and/or stdint.h if necessary. Add copyright notices. * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h (ldbl_canonicalize_int): Don't use EXTRACT_WORDS64. * sysdeps/ieee754/ldbl-96/test-canonical-ldbl-96.c * sysdeps/ieee754/ldbl-96/test-totalorderl-ldbl-96.c * sysdeps/ieee754/ldbl-128ibm/test-canonical-ldbl-128ibm.c * sysdeps/ieee754/ldbl-128ibm/test-totalorderl-ldbl-128ibm.c: Include math_ldbl.h, not math_private.h. --- ChangeLog | 26 +++++++++++ sysdeps/generic/math_ldbl.h | 10 +++-- sysdeps/generic/math_private.h | 4 +- sysdeps/ia64/fpu/math_ldbl.h | 40 +++++++++++++---- sysdeps/ieee754/ldbl-128/math_ldbl.h | 44 ++++++++++++++----- sysdeps/ieee754/ldbl-128ibm/math_ldbl.h | 37 +++++++++++++--- .../ldbl-128ibm/test-canonical-ldbl-128ibm.c | 2 +- .../test-totalorderl-ldbl-128ibm.c | 2 +- sysdeps/ieee754/ldbl-96/math_ldbl.h | 40 +++++++++++++---- .../ieee754/ldbl-96/test-canonical-ldbl-96.c | 2 +- .../ldbl-96/test-totalorderl-ldbl-96.c | 2 +- sysdeps/powerpc/fpu/math_ldbl.h | 25 +++++++++-- sysdeps/x86_64/fpu/math_ldbl.h | 31 ++++++++++--- 13 files changed, 212 insertions(+), 53 deletions(-) diff --git a/ChangeLog b/ChangeLog index b2bc03ebe1..eeccfed101 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,29 @@ +2017-02-25 Zack Weinberg + + * sysdeps/generic/math_private.h: Use __BIG_ENDIAN and + __LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN. + + * sysdeps/generic/math_ldbl.h + * sysdeps/ia64/fpu/math_ldbl.h + * sysdeps/ieee754/ldbl-128/math_ldbl.h + * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h + * sysdeps/ieee754/ldbl-96/math_ldbl.h + * sysdeps/powerpc/fpu/math_ldbl.h + * sysdeps/x86_64/fpu/math_ldbl.h: + Allow direct inclusion.
