2020-07-10c: Add C2X BOOL_MAX and BOOL_WIDTH to limits.hJoseph Myers1-0/+8
C2X adds BOOL_MAX and BOOL_WIDTH macros to <limits.h>. As GCC only supports values 0 and 1 for _Bool (regardless of the number of bits in the representation, other bits are padding bits and if any of them are nonzero, the representation is a trap representation), the values of those macros can just be hardcoded directly in <limits.h> rather than needing corresponding predefined macros. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/ * glimits.h [__STDC_VERSION__ > 201710L] (BOOL_MAX, BOOL_WIDTH): New macros. gcc/testsuite/ * gcc.dg/c11-bool-limits-1.c, gcc.dg/c2x-bool-limits-1.c: New tests.

2019-10-03Define WIDTH macros for C2x.Joseph Myers1-2/+3
As part of the integration of TS 18661-1 into C2x, many features became unconditional features not depending on any feature test macro being defined. This patch updates the conditionals on the *_WIDTH macros in limits.h and stdint.h accordingly so that they are defined for C2x. The macro CR_DECIMAL_DIG in float.h does still require __STDC_WANT_IEC_60559_BFP_EXT__ to be defined, and a test for this is added. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * ginclude/stdint-gcc.h [__STDC_WANT_IEC_60559_BFP_EXT__]: Change condition on WIDTH macros to [__STDC_WANT_IEC_60559_BFP_EXT__ || (__STDC_VERSION__ && __STDC_VERSION__ > 201710L)]. * glimits.h: Likewise. gcc/testsuite: * gcc.dg/cr-decimal-dig-2.c: New test. * gcc.dg/limits-width-2.c: New test. Based on limits-width-1.c. * gcc.dg/stdint-width-2.c: New test. Based on stdint-width-1.c. From-SVN: r276497

2016-09-09Define TS 18661-1 type width macros in <limits.h> and <stdint.h>.Joseph Myers1-0/+26
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.
