2016-09-09Define TS 18661-1 type width macros in <limits.h> and <stdint.h>.Joseph Myers9-7/+482
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.

2016-09-09runtime: align ucontext_t argument to 16 byte boundaryIan Lance Taylor1-1/+1
Some systems, such as ia64 and PPC, require that a ucontext_t pointer passed to getcontext and friends be aligned to a 16-byte boundary. Currently the ucontext_t fields in the g structure are defined in Go, and Go has no way to ensure a 16-byte alignment for a struct field. The fields are currently represented by an array of unsafe.Pointer. Enforce the alignment by making the array larger, and picking an offset into the array that is 16-byte aligned.
