src/sys/amd64/include/stdarg.h, branch release/13.2.0

Copy amd64 stdarg.h to x86 and replace amd64/i386/pc98 stdarg.h with stubs.

Use __builtin_va_start instead of __builtin_stdarg_start. GCC4 obsoletes

the former and __builtin_va_start was present in all GCC version 3.1 and later.

Remove diffs to i386 version that came in via the compiler support ifdefs.

This changes things like whitespace, inconsistent use of #ifndef vs #if !defined(), different macro argument orders, mismatched comments, etc.

netchild's mega-patch to isolate compiler dependencies into a central

place. This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

Add __va_copy and make it always visible, in spite of the __ISO_C_VISIBLE

setting. Make va_copy be an alias if __ISO_C_VISIBLE >= 1999. Why? more than a few ports have an autoconf that looks for __va_copy because it is available on glibc. It is critical that we use it if at all possible on amd64. It generally isn't a problem for i386 and its ilk because autoconf driven code tends to fall back to an assignment.

o Add conditionals to allow va_list to be defined in other headers.

o Standardize on _MACHINE_STDARG_H_ to allow multiple header includes. o Restrict the definition of va_copy() to C99 environments.

Implement C99's va_copy() macro.

called . o will continue to live so it can define MD clock macros, which are only MD because of gratuitous differences between architectures. o Change all headers to make use of this. This mainly involves changing: #ifdef _BSD_FOO_T_ typedef _BSD_FOO_T_ foo_t; #undef _BSD_FOO_T_ #endif to: #ifndef _FOO_T_DECLARED typedef __foo_t foo_t; #define _FOO_T_DECLARED #endif Concept by: bde Reviewed by: jake, obrien
