* Fix bug in SplitEditor::splitLiveThroughBlock when switching registers.Jakob Stoklund Olesen2011-07-231-5/+14
| | | | | | | | | | | If there is no interference and no last split point, we cannot enterIntvBefore(Stop) - that function needs a real instruction. Use enterIntvAtEnd instead for that very easy case. This code doesn't currently run, it is needed by multi-way splitting. llvm-svn: 135846
* Prepare RAGreedy::growRegion for compact regions.Jakob Stoklund Olesen2011-07-231-1/+8
| | | | | | | | | | | | | | | A split candidate can have a null PhysReg which means that it doesn't map to a real interference pattern. Instead, pretend that all through blocks have interference. This makes it possible to generate compact regions where the live range doesn't go through blocks that don't use it. The live range will still be live between directly connected blocks with uses. Splitting around a compact region tends to produce a live range with a high spill weight, so it may evict a less dense live range. llvm-svn: 135845
* Add a simple method for marking blocks with interference in and out.Jakob Stoklund Olesen2011-07-232-0/+18
| | | | | | | | | | This method matches addLinks - All the listed blocks are considered to have interference, so they add a negative bias to their bundles. This could also be done by addConstraints, but that requires building a separate BlockConstraint array. llvm-svn: 135844
* Allow null interference cursors to be queried.Jakob Stoklund Olesen2011-07-232-2/+6
| | | | | | They always report 'no interference'. llvm-svn: 135843

* ARM SSAT instruction 5-bit immediate handling.Jim Grosbach2011-07-228-23/+37
| | | | | | | | | The immediate is in the range 1-32, but is encoded as 0-31 in a 5-bit bitfield. Update the representation such that we store the operand as 0-31, allowing us to remove the encoder method and the special case handling in the disassembler. Update the assembly parser and the instruction printer accordingly. llvm-svn: 135823
* Move the last uses of RetainFunc etc. over to using getRetainCallee() etc.Dan Gohman2011-07-221-23/+35

* 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

* 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
