MFC r262613:
Merge the projects/clang-sparc64 branch back to head. This brings in several updates from the llvm and clang trunks to make the sparc64 backend fully functional.
Apart from one patch to sys/sparc64/include/pcpu.h which is still under discussion, this makes it possible to let clang fully build world and kernel for sparc64.
Any assistance with testing this on actual sparc64 hardware is greatly appreciated, as there will unavoidably be bugs left.
Many thanks go to Roman Divacky for his upstream work on getting the sparc64 backend into shape.
MFC r262985:
Repair a few minor mismerges from r262261 in the clang-sparc64 project branch. This is also to minimize differences with upstream.

Upgrade our copy of llvm/clang to 3.4 release. This version supports all of the features in the current working draft of the upcoming C++ standard, provisionally named C++1y.
The code generator's performance is greatly increased, and the loop auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The PowerPC backend has made several major improvements to code generation quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ backends have all seen major feature work.

Pull in r196874 from upstream llvm trunk:
Fix a crash that occurs when PWD is invalid.
MCJIT needs to be able to run in hostile environments, even when PWD is invalid. There's no need to crash MCJIT in this case.
The obvious fix is to simply leave MCContext's CompilationDir empty when PWD can't be determined. This way, MCJIT clients, and other clients that link with LLVM don't need a valid working directory.
If we do want to guarantee valid CompilationDir, that should be done only for clients of getCompilationDir(). This is as simple as checking for an empty string.
The only current use of getCompilationDir is EmitGenDwarfInfo, which won't conceivably run with an invalid working dir. However, in the purely hypothetically and untestable case that this happens, the AT_comp_dir will be omitted from the compilation_unit DIE.
This should help fix assertions occurring with ports-mgmt/tinderbox, when it is using jails, and sometimes invalidates clang's current working directory.

MFC r241214 (by jkim): Do not install incomplete unwind.h from clang. This header file was meant to be a wrapper for the canonical system header file. Unfortunately, we do not have one (yet) and some times it is causing weird failures when clang is used for building ports. More complete and correct file will come from libcxxrt in the future.
Discussed with: dim, kib, theraven
MFC r246705 (by andrew): Allow us to build clang for ARM EABI. Clang and llvm use the arm-gnueabi-freebsd10.0 triple for EABI. Use this when we are on arm or armv6 and are building for EABI.

MFC r249423: Upgrade our copy of llvm/clang to trunk r178860, in preparation of the upcoming 3.3 release (branching and freezing expected in a few weeks).
Preliminary release notes can be found at the usual location: <http://llvm.org/docs/ReleaseNotes.html>
An MFC is planned once the actual 3.3 release is finished.
MFC r249817: Pull in r180121 from upstream llvm trunk:
LoopVectorizer: Fix 15830. When scalarizing and unrolling stores make sure that the order in which the elements are scalarized is the same as the original order. This fixes a miscompilation in FreeBSD's regex library.
This should fix lib/libc/regex/regcomp.c at -O3 with clang 3.3 r178860 on CPUs with SSE. Before this change, the vectorizer could incorrectly rearrange the second loop in computejumps(), leading to possibly invalid entries in the re_gets::charjump table.
The net result was that for example "sed s/@CC@/foo/" failed to work correctly, leading to trouble with many configure scripts.
MFC r250217: Allow building clang on older FreeBSD releases, where log2() does not exist yet. With this change, I have verified that building head on 8.1-RELEASE works.

MFC r250593: Pull in r181286 from upstream llvm trunk:
LoopVectorize: getConsecutiveVector must respect signed arithmetic
We were passing an i32 to ConstantInt::get where an i64 was needed and we must also pass the sign if we pass negatives numbers. The start index passed to getConsecutiveVector must also be signed.
Should fix PR15882.
This should fix Firefox crashes some people have been reporting, when it is compiled with -O3.
MFC r250616: Use an ugly hack to get around bootstrapping problems when building clang on head between r239347 and r245428.
The former revision introduced CLOCK_PROCESS_CPUTIME_ID as a clock id for the clock_gettime() function and friends, but it was only added in <sys/time.h>, not in <time.h>. Any program including <time.h> would therefore not be able to use CLOCK_PROCESS_CPUTIME_ID, even though the value of _POSIX_CPUTIME indicates its existence. The latter revision synchronized the defines again.
Work around this problem by defining the id on the command line for the particular .cpp file that needs it. If the id ever changes value, this hack will need to be updated.
MFC r250997: Pull in r182656 from upstream llvm trunk:
LoopVectorize: LoopSimplify can't canonicalize loops with an indirectbr in it, don't assert on those cases.

MFC r251216 (by ed): Pull in r183033 and r183036 from LLVM trunk:
Add support for optimized (non-generic) atomic libcalls.
For integer types of sizes 1, 2, 4 and 8, libcompiler-rt (and libgcc) provide atomic functions that pass parameters by value and return results directly.
libgcc and libcompiler-rt only provide optimized libcalls for __atomic_fetch_*, as generic libcalls on non-integer types would make little sense. This means that we can finally make __atomic_fetch_* work on architectures for which we don't provide these operations as builtins (e.g. ARM).
This should fix the dreaded "cannot compile this atomic library call yet" error that would pop up once every while.
This should make it possible for me to get C11 atomics working on all of our platforms.
MFC r251662: Upgrade our copy of llvm/clang to 3.3 release.
Release notes are still in the works, these will follow soon.
MFC r251761: Pull in r181620 from llvm trunk:
[ms-inline asm] Fix a crasher when we fail on a direct match.
The issue was that the MatchingInlineAsm and VariantID args to the MatchInstructionImpl function weren't being set properly. Specifically, when parsing intel syntax, the parser thought it was parsing inline assembly in the at&t dialect; that will never be the case.
The crash was caused when the emitter tried to emit the instruction, but the operands weren't set. When parsing inline assembly we only set the opcode, not the operands, which is used to lookup the instruction descriptor. rdar://13854391 and PR15945
Also, this commit reverts r176036. Now that we're correctly parsing the intel syntax the pushad/popad don't match properly. I've reimplemented that fix using a MnemonicAlias.
Pull in r183907 from llvm trunk:

MFC r251785 (by ed) Pull in r184040 from upstream clang trunk:
Emit native implementations of atomic operations on FreeBSD/armv6.
Just like on Linux, FreeBSD/armv6 assumes the system supports ldrex/strex unconditionally. It is also used by the kernel. We can therefore enable support for it, like we do on Linux.
While there, change one of the unit tests to explicitly test against armv5 instead of armv7, as it actually tests whether libcalls are emitted.
MFC r251790 (by andrew): Pull in r183926 from LLVM trunk:
Allow clang to build __clear_cache on ARM.
__clear_cache is special. It needs no signature, but is a real function in compiler_rt or libgcc.
Patch by Andrew Turner.
This allows us to build the __clear_cache function in compiler-rt.
MFC r252039: Pull in r183984 from llvm trunk:
Make PrologEpilogInserter save/restore all callee saved registers in functions which call __builtin_unwind_init()
__builtin_unwind_init() is an undocumented gcc intrinsic which has this effect, and is used in libgcc_eh.
Goes part of the way toward fixing PR8541.
This obsoletes the ugly hack to libgcc's unwind code from r245272, and should also work for other arches, so revert the hack too.

Pull in r172354 from upstream clang trunk:
Refactor the x86 CPU name logic in the driver and pass -march and -mcpu flag information down from the Clang driver into the Gold linker plugin for LTO. This allows specifying -march on the linker commandline and should hopefully have it pass all the way through to the LTO optimizer.
Fixes PR14697.
Pull in r175919 from upstream clang trunk:
Driver: Pass down the -march setting down to -cc1as on x86 too.
The assembler historically didn't make use of any target features, but this has changed when support for old CPUs that don't support long nops was added.
This should fix the long nops that still occurred in crt*.o, and possibly other object files, if the system was compiled for a CPU that does not support those, such as Geode.
Note that gcc on i386 also does not pass through any -march, -mcpu or -mtune setting to gas, but this has not caused any trouble yet, because gas defaults to i386.

Update llvm/clang to trunk r126547.
There are several bugfixes in this update, but the most important one is to ensure __start_ and __stop_ symbols for linker sets and kernel module metadata are always emitted in object files:
http://llvm.org/bugs/show_bug.cgi?id=9292
Before this fix, if you compiled kernel modules with clang, they would not be properly processed by kldxref, and if they had any dependencies, the kernel would fail to load those. Another problem occurred when attempting to mount a tmpfs filesystem, which would result in 'operation not supported by device'.

Recently, in upstream clang, a fix was done to add -L/usr/lib to the arguments passed to ld, when linking. This was to appease configure scripts in several ports, that grep for such a -L option in "${CC} -v" output, to determine the startup objects passed to ld. Note ld itself does not need to be told about /usr/lib, since it has this path builtin anyway.
However, if clang is built as a bootstrap tool during buildworld, it should not use *anything* outside ${WORLDTMP} to include or link with. The upstream fix to add -L/usr/lib breaks this assumption, and can thus cause libraries from /usr/lib to be linked in during buildworld.
This can result in buildworld dying during linking of zinject, where it picks up the wrong copy of libzpool.so, eventually leading to:
/usr/obj/usr/src/tmp/lib/libthr.so.3: undefined reference to `_rtld_get_stack_prot'
Fix this issue by not adding any hardcoded paths, but by looping through the run-time library path list, which is already correctly set for the bootstrap phase.
