2011-05-31Simplify the eviction policy by making the failsafe explicit.Jakob Stoklund Olesen
When assigned ranges are evicted, they are put in the RS_Evicted stage and are not allowed to evict anything else. That prevents looping automatically. When evicting ranges just to get a cheaper register, use only spill weights to find the possible candidates. Avoid breaking hints for this purpose, it is not worth it. Start implementing more complex eviction heuristics, guarded by the temporary -complex-eviction flag. The initial version permits a heavier range to be evicted if it doesn't have any uses where the evicting range is live. This makes it a good candidate for live ranfge splitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132358 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-29Fix PR10046 by updating LiveVariables kill info when splitting live ranges.Jakob Stoklund Olesen
This only affects targets like Mips where branch instructions may kill virtual registers. Most other targets branch on flag values, so virtual registers are not involved. The problem is that MachineBasicBlock::updateTerminator deletes branches and inserts new ones while LiveVariables keeps a list of pointers to instructions that kill virtual registers. That list wasn't properly updated in MBB::SplitCriticalEdge. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132298 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-29When generating against the Win64 EH scheme, set the handler to the GCC-specificCharles Davis
handler. At this moment, only GCC-style exceptions are supported. Other kinds of exceptions, including "traditional" SEH and Microsoft Visual C++ exceptions, need more work--and an compiler exception model that isn't specific to GCC-style exceptions! In particular, I imagine that it would be possible to mix "traditional" SEH with GCC-style EH or Microsoft C++ EH. Currently LLVM has no way (beyond some target-specific defaults and whole-module compiler switches) of knowing which scheme to use when. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132283 91177308-0d34-0410-b5e6-96231b3b80d8
