Copy amd64 endian.h to x86 and merge with i386 endian.h. Replace amd64/i386/pc98 endian.h with stubs.
In __bswap64_const(x) the conflict between 0xffUL and 0xffULL has been resolved by reimplementing the macro in terms of __bswap32(x). As a side effect __bswap64_var(x) is now implemented using two bswap instructions on i386 and should be much faster. __bswap32_const(x) has been reimplemented in terms of __bswap16(x) for consistency.

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.

These are changes to allow to use the Intel C/C++ compiler (lang/icc) to build the kernel. It doesn't affect the operation if gcc.
Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as icc v8 may define __GNUC__ some parts may look strange but are necessary.
Additional changes: - in_cksum.[ch]: * use a generic C version instead of the assembly version in the !gcc case (ASM code breaks with the optimizations icc does) -> no bad checksums with an icc compiled kernel Help from: andre, grehan, das Stolen from: alpha version via ppc version The entire checksum code should IMHO be replaced with the DragonFly version (because it isn't guaranteed future revisions of gcc will include similar optimizations) as in: ---snip--- Revision Changes Path 1.12 +1 -0 src/sys/conf/files.i386 1.4 +142 -558 src/sys/i386/i386/in_cksum.c 1.5 +33 -69 src/sys/i386/include/in_cksum.h 1.5 +2 -0 src/sys/netinet/igmp.c 1.6 +0 -1 src/sys/netinet/in.h 1.6 +2 -0 src/sys/netinet/ip_icmp.c

and finally remove sys/i386/i386 in_cksum.c sys/i386/include in_cksum.h ---snip--- - endian.h: * DTRT in C++ mode - quad.h: * we don't use gcc v1 anymore, remove support for it Suggested by: bde (long ago) - assym.h: * avoid zero-length arrays (remove dependency on a gcc specific feature) This change changes the contents of the object file, but as it's only used to generate some values for a header, and the generator knows how to handle this, there's no impact in the gcc case. Explained by: bde Submitted by: Marius Strobl <marius@alchemy.franken.de> - aicasm.c: * minor change to teach it about the way icc spells "-nostdinc" Not approved by: gibbs (no reply to my mail) - bump __FreeBSD_version (lang/icc needs to know about the changes)
Incarnations of this patch survive gcc compiles since a loooong time, I use it on my desktop. An icc compiled kernel works since Nov. 2003 (exceptions: snd_* if used as modules), it survives a build of the entire ports collection with icc.

Microoptimization to allow the compiler to evaluate ntohl() etc on known constants at compile time rather than at run time. We have a number of nasty hacks around the place to cache ntohl() of constants (eg: nfs). This change allows the compiler to compile-time evaluate ntohl(1) as 0x01000000 rather than having to emit assembler code to do it. This has other smaller flow-on effects because the compiler can see that ntohl(constant) itself has a constant value now and can propagate the compile time evaluation.

Add the following functions/macros to support byte order conversions and device drivers for bus system with other endinesses than the CPU (using interfaces compatible to NetBSD):
- bwap16() and bswap32(). These have optimized implementations on some architectures; for those that don't, there exist generic implementations. - macros to convert from a certain byte order to host byte order and vice versa, using a naming scheme like le16toh(), htole16(). These are implemented using the bswap functions. - stream bus space access functions, which do not perform a byte order conversion (while the normal access functions would if the bus endianess differs from the CPU endianess).
htons(), htonl(), ntohs() and ntohl() are implemented using the new functions above for kernel usage. None of the above interfaces is currently exported to user land.
Make use of the new functions in a few places where local implementations of the same functionality existed.

Back out wrapping the asm ... ; bits in #ifndef lint macros. There are some good reasons for not doing this, even if the linting of the code breaks.
1) If lint were ever to understand the stuff inside the macros, that would break the checks.
2) There are ways to use __GNUC__ to exclude overly specific code.
3) (Not yet practical) Lint(1) needs to properlyu understand all of te code we actually run.

Fixed linting of and compilation of the gcc byte-swapping macros properly. Simply don't use the gcc macros if we're not gcc, and declare prototypes for the byte-swapping functions in case the macro versions are not used. The previous fix was wrong and broke libpcap, which abuses -Dlint.
Don't pollute the namespace if _POSIX_SOURCE is defined. This is broken - it makes almost everything in <machine/endian.h> inaccessible if _POSIX_SOURCE is defined, yet <machine/endian.h> is not a POSIX header. Other systems don't do it any better.
