2016-09-29[RS6000] .gnu.attributes Tag_GNU_Power_ABI_FPAlan Modra1-0/+9
Extend this attribute to cover long double ABIs, for 64-bit too. This patch also corrects an error that crept in to code setting rs6000_passes_float. See the added comment. Passing IEEE128 values in vsx regs ought to set both Tag_GNU_Power_ABI_FP and Tag_GNU_Power_ABI_Vector. Also adds a new option, default on, that disables output of .gnu_attribute assembly directives. * config/rs6000/sysv4.opt (mgnu-attribute): New option. * doc/invoke.texi: Document it. * config/rs6000/rs6000.c (HAVE_LD_PPC_GNU_ATTR_LONG_DOUBLE): Define.

2016-09-09Define TS 18661-1 type width macros in <limits.h> and <stdint.h>.Joseph Myers1-0/+27
TS 18661-1 defines <limits.h> and <stdint.h> macros for widths of standard integer types and the typedefs defined in, or whose limits are defined in, <stdint.h>. (The connection to the main floating-point subject matter of TS 18661-1 is that these are intended to be used with the fromfp functions to convert from floating point to integer types of any width in any rounding direction, though these macros may be of more general use.) This patch implements support for these macros in GCC's <limits.h> and <stdint.h>. To avoid needing to implement fixincludes for system headers where GCC wraps the system libc's <stdint.h> in hosted mode, the test for the <stdint.h> macros uses -ffreestanding (I'll add the macros to glibc's headers separately) - but as usual for new features in these headers, platforms (primarily OpenBSD) that use USER_H to avoid using GCC's headers at all will have failures until the system headers have the feature added or appropriate fixincludes are implemented. The header macros are implemented using appropriate new predefined macros, with the code avoiding defining more such macros than necessary (so one predefined macro suffices for corresponding signed and unsigned types, while no such predefined macros are needed for the exact-width types such as int8_t). Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * doc/cpp.texi (__SCHAR_WIDTH__, __SHRT_WIDTH__, __INT_WIDTH__) (__LONG_WIDTH__, __LONG_LONG_WIDTH__, __PTRDIFF_WIDTH__) (__SIG_ATOMIC_WIDTH__, __SIZE_WIDTH__, __WCHAR_WIDTH__) (__WINT_WIDTH__, __INT_LEAST8_WIDTH__, __INT_LEAST16_WIDTH__) (__INT_LEAST32_WIDTH__, __INT_LEAST64_WIDTH__) (__INT_FAST8_WIDTH__, __INT_FAST16_WIDTH__, __INT_FAST32_WIDTH__) (__INT_FAST64_WIDTH__, __INTPTR_WIDTH__, __INTMAX_WIDTH__): Document. * ginclude/stdint-gcc.h [__STDC_WANT_IEC_60559_BFP_EXT__]: Define width macros from TS 18661-1. * glimits.h [__STDC_WANT_IEC_60559_BFP_EXT__]: Likewise. gcc/c-family: * c-cppbuiltin.c (builtin_define_type_width): New function.

2016-08-26Tweak to colors of fix-it hintsDavid Malcolm1-7/+21
Previous, fix-it hints were printed using the color of the severity of the diagnostic (magenta for warnings, red for errors, cyan for notes). This patch updates fix-it hints so that replacement text is printed in green, to better distinguish the suggested improvement from the current code. For example: spellcheck-fields.cc:52:13: error: 'struct s' has no member named 'colour'; did you mean 'color'? return ptr->colour; <<< RED ^~~~~~ <<< RED color <<< GREEN It makes sense for the underlinings that indicate deletions to be printed in red, so the patch changes that also.

MULTILIB_OPTIONS should be used. 2016-08-24 Thomas Preud'homme <thomas.preudhomme@arm.com> * doc/fragments.texi (MULTILIB_REUSE): Mention that only options in MULTILIB_OPTIONS should be used. Small wording fixes. * genmultilib: Memorize set of all option combinations in combination_space. Detect if RHS of MULTILIB_REUSE uses an option not found in MULTILIB_OPTIONS by checking if option set is listed in combination_space. Output new and existing error message to stderr.
