On mixed 32/64 bit architectures (mips, powerpc) use LP64 rather than

2011-01-08T12:43:05Z

architecture macros (__mips_n64, __powerpc64__) when 64 bit types (and corresponding macros) are different from 32 bit. [1] Correct the type of INT64_MIN, INT64_MAX and UINT64_MAX. Define (U)INTMAX_C as an alias for (U)INT64_C matching the type definition for (u)intmax_t. Do this on all architectures for consistency. Suggested by: bde [1] Approved by: kib (mentor)

Fix types of some values in machine/_limits.h.

On some architectures UCHAR_MAX and USHRT_MAX had type unsigned int. However, lacking integer suffixes for types smaller than int, their type should correspond to that of an object of type unsigned char (or short) when used in an expression with objects of type int. In that case unsigned char (short) are promoted to int (i.e. signed) so the type of UCHAR_MAX and USHRT_MAX should also be int. Where MIN/MAX constants implicitly have the correct type the suffix has been removed. While here, correct some comments. Reviewed by: bde Approved by: kib (mentor)

Remove unused support for 64 bit long on 32 bit architectures.

It was used mainly to discover and fix some 64-bit portability problems before 64-bit arches were widely available. Discussed with: bde Approved by: kib (mentor)

Kernel sources for 64-bit PowerPC, along with build-system changes to keep 32-bit kernels compiling (build system changes for 64-bit kernels are coming later). Existing 32-bit PowerPC kernel configurations must be updated after this change to specify their architecture.

it to __MINSIGSTKSZ. Define MINSIGSTKSZ in . This is done in order to use MINSIGSTKSZ for the macro PTHREAD_STACK_MIN in (soon ) without having to include the whole header. Discussed with: bde

Remove DBL_DIG, DBL_MIN, DBL_MAX and their FLT_ counterparts, they were marked for deprecation ever since SUSv1 at least. Only define ULLONG_MIN/MAX and LLONG_MAX if long long type is supported. Restore a lost comment in MI _limits.h file and remove it from sys/limits.h where it does not belong.

Add a new sys/limits.h file which in turn depends on machine/_limits.h
