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.

Remove the advertsing clause, per the Regent's letter dated July 22, 1999.

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

Add manifest constants: _LITTLE_ENDIAN, _BIG_ENDIAN, _PDP_ENDIAN, and

_BYTE_ORDER. These are far more useful than their non-underscored equivalents as these can be used in restricted namespace environments. Mark the non-underscored variants as deprecated.

o Don't require long long support in bswap64() functions.

o In i386's , macros have some advantages over inlines, so change some inlines to macros. o In i386's , ungarbage collect word_swap_int() (previously __uint16_swap_uint32), it has some uses on i386's with PDP endianness. Submitted by: bde o Move a comment up in that was accidentially moved down a few revisions ago. o Reenable userland's use of optimized inline-asm versions of byteorder(3) functions. o Fix ordering of prototypes vs. redefinition of byteorder(3) functions, so that the non-GCC (libc asm) case has proper prototypes. o Add proper prototypes for byteorder(3) functions in . o Prevent redundant duplicate prototypes by making use of the _BYTEORDER_PROTOTYPED define. o Move the bswap16(), bswap32(), bswap64() C functions into MD space for platforms in which asm versions don't exist. This significantly reduces the complexity of some things at the cost of duplicate code. Reviewed by: bde
