Some cleanups and tweaks to some of the atomic.h files in preparation for further changes and fixes in the future: - Use aliases via macros rather than duplicated inlines wherever possible. - Move all the aliases to the bottom of these files and the inline functions to the top. - Add various comments. - On alpha, drop atomic_{load_acq,store_rel}_{8,char,16,short}(). - On i386 and amd64, don't duplicate the extern declarations for functions in the two non-inline cases (KLD_MODULE and compiler doesn't do inlines), instead, consolidate those two cases. - Some whitespace fixes.

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.

- Place the gcc memory barrier hint in the right place in the 80386 version of atomic_store_rel(). - Use the 80386 versions of atomic_load_acq() and atomic_store_rel() that do not use serializing instructions on all UP kernels since a UP machine does need to synchronize with other CPUs. This trims lots of cycles from spin locks on UP kernels among other things.

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

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.
Parts of this commit contains suggestions or submissions from Marius Strobl <marius@alchemy.franken.de>.

Use newer constraints for inline assembly for an operand that is both an input and an output by using the '+' modifier rather than listing the operand in both the input and output sections.

Allow atomic ops to be somewhat safely used in userland. We always use lock prefixes in the userland case so that the binaries will work on both SMP and UP systems.

- Sort of lie and say that %eax is an output only and not an input for the non-386 atomic_load_acq(). %eax is an input since its value is used in the cmpxchg instruction, but we don't care what value it is, so setting it to a specific value is just wasteful. Thus, it is being used without being initialized as the warning stated, but it is ok for it to be used because its value isn't important. Thus, we are only sort of lying when we say it is an output only operand. - Add "cc" to the clobber list for atomic_load_acq() since the cmpxchgl changes ZF.

- Fix atomic_load_* and atomic_store_* to generate functions for atomic.c that modules can call. - Remove the old gcc <= 2.8 versions of the atomic ops. - Resort the order of some things in the file so that there is only one #ifdef for KLD_MODULE, and so that all WANT_FUNCTIONS stuff is moved to the bottom of the file. - Remove ATOMIC_ACQ_REL() and just use explicit macros instead.

The x86 atomic operations are already locked, so they do not need an additional locked instruction to guarantee a write barrier for the acquire variants.
