* Move TargetRegistry.cpp from lib/Support to lib/Target where it belongs.Chandler Carruth2011-07-223-1/+1
| | | | | | | | | | | | | | The header file was already properly located. The previous need for it in Support had to do with the version string printing which was fixed in r135757. Also update build dependencies where libraries that needed the functionality of the Target library (in the form of the TargetRegistry) were picking it up via Support. This is pretty pervasive, essentially every TargetInfo library (ARMInfo, etc) uses TargetRegistry, making it depend on Target. All of these were previously just sneaking by. llvm-svn: 135760

* Move the registered target printing in version strings completely out ofChandler Carruth2011-07-221-7/+2
| | | | | | | | | | | | | | | | | the Support library. Now its part of the TargetRegistry, and the three commands that care about this explicitly register this extra bit of version information. The set of commands which care was computed by intersecting those which use the Support library's version string printing and those that initialize all the registered targets in a way that produces a meaningful list. The only odd ball out is that 'clang -cc1as -version' no longer prints the registered targets. I don't think anyone is really interested in that (especially as the fact that llvm-mc does so is under a FIXME), but if someone really does want this back I'll happily apply the same patch there. llvm-svn: 135757
* Move the logic for printing the registered targets into a staticChandler Carruth2011-07-222-26/+35
| | | | | | | function on the TargetRegistry. Also clean it up and use the modern LLVM utility libraries available instead of rolling a few things manually. llvm-svn: 135756
* Add an extension point to the CommandLine library where clients canChandler Carruth2011-07-221-3/+22
| | | | | | | | | | | | register extra version information to be printed. This is designed to allow those tools which link in various targets to also print those registered targets under --version. Currently this printing logic is embedded into the Support library directly; a huge layering violation. This is the first step to hoisting it out into the tools without adding lots of duplicated code. llvm-svn: 135755
* lib/Support/Triple.cpp: Recognize "-march=ppc32" to llc properly, as quick hack.NAKAMURA Takumi2011-07-221-0/+2

Also remove the ConcatVectors function, which is unused now. - Fix a introduction of useless nodes in r126664 and r126264. The VUNPCKL* should never be introduced cause we don't want duplicate nodes for 128 AVX and non-AVX modes, the actual instruction difference only exists during isel, but not for target specific DAG nodes. We only introduce V* target nodes when there is no 128-bit version already there. - Fix a fragile test and make it more useful. llvm-svn: 135729

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | instruction introduced in AVX, which can operate on 128 and 256-bit vectors. It considers a 256-bit vector as two independent 128-bit lanes. It can permute any 32 or 64 elements inside a lane, and restricts the second lane to have the same permutation of the first one. With the improved splat support introduced early today, adding codegen for this instruction enable more efficient 256-bit code: Instead of: vextractf128 $0, %ymm0, %xmm0 punpcklbw %xmm0, %xmm0 punpckhbw %xmm0, %xmm0 vinsertf128 $0, %xmm0, %ymm0, %ymm1 vinsertf128 $1, %xmm0, %ymm1, %ymm0 vextractf128 $1, %ymm0, %xmm1 shufps $1, %xmm1, %xmm1 movss %xmm1, 28(%rsp) movss %xmm1, 24(%rsp) movss %xmm1, 20(%rsp) movss %xmm1, 16(%rsp) vextractf128 $0, %ymm0, %xmm0 shufps $1, %xmm0, %xmm0 movss %xmm0, 12(%rsp) movss %xmm0, 8(%rsp) movss %xmm0, 4(%rsp) movss %xmm0, (%rsp) vmovaps (%rsp), %ymm0 We get: vextractf128 $0, %ymm0, %xmm0 punpcklbw %xmm0, %xmm0 punpckhbw %xmm0, %xmm0 vinsertf128 $0, %xmm0, %ymm0, %ymm1 vinsertf128 $1, %xmm0, %ymm1, %ymm0 vpermilps $85, %ymm0, %ymm0 llvm-svn: 135662
