It can calculate from these what the compact unwind should look like. This is currently disabled because of needed linker support.

* Move some ELF directives into ELF asm parser.Jim Grosbach2011-07-255-15/+78
| | | | | | | | | | | | | | | The .local, .hidden, .internal, and .protected are not legal for all supported file formats (in particular, they're invalid for MachO). Move the parsing for them into the ELF assembly parser since that's the format they're for. Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing to the COFF and ELF asm parsers. Previously, using any of these directives on Darwin would result in an assertion failure in the parser; now we get a diagnostic as we should. rdar://9827089 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135921 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an RS_Split2 stage used for loop prevention.Jakob Stoklund Olesen2011-07-251-15/+24
| | | | | | | | | | | | | | | | This mechanism already exists, but the RS_Split2 stage makes it clearer. When live range splitting creates ranges that may not be making progress, they are marked RS_Split2 instead of RS_New. These ranges may be split again, but only in a way that can be proven to make progress. For local ranges, that means they must be split into ranges used by strictly fewer instructions. For global ranges, region splitting is bypassed and the RS_Split2 ranges go straight to per-block splitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135912 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename live range stages to better reflect how they are used.Jakob Stoklund Olesen2011-07-251-32/+40
| | | | | | | | | | | | The stage is used to control where a live range is going, not where it is coming from. Live ranges created by splitting will usually be marked RS_New, but some are marked RS_Spill to avoid wasting time trying to split them again. The old RS_Global and RS_Local stages are merged - they are really the same thing for local and global live ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135911 91177308-0d34-0410-b5e6-96231b3b80d8

* Add RAGreedy::calcCompactRegion.Jakob Stoklund Olesen2011-07-231-0/+46
| | | | | | | | | | | | | | | | This method computes the edge bundles that should be live when splitting around a compact region. This is independent of interference. The function returns false if the live range was already a compact region, or the compact region doesn't have any live bundles - it would be the same as splitting around basic blocks. Compact regions are computed using the normal spill placement code. We pretend there is interference in all live-through blocks that don't use the live range. This removes all edges from the Hopfield network used for spill placement, so it converges instantly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135847 91177308-0d34-0410-b5e6-96231b3b80d8
