2012-09-17Merge into undefined lanes under -new-coalescer.Jakob Stoklund Olesen
Add LIS::pruneValue() and extendToIndices(). These two functions are used by the register coalescer when merging two live ranges requires more than a trivial value mapping as supported by LiveInterval::join(). The pruneValue() function can remove the part of a value number that is going to conflict in join(). Afterwards, extendToIndices can restore the live range, using any new dominating value numbers and updating the SSA form. Use this complex value mapping to support merging a register into a vector lane that has a conflicting value, but the clobbered lane is undef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164074 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-16Fix problem when using LiveRangeQuery with block entries.Jakob Stoklund Olesen
A value that is live in to a basic block should be returned by valueIn() in LiveRangeQuery(getMBBStartIdx(MBB)), unless it is a PHI-def which should be returned by valueDefined() instead. Current code isn't using this functionality. Future code will. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163990 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-15Make LiveRangeQuery work for PHIDefs as well.Jakob Stoklund Olesen
If a PHI value happens to be live out from the layout predecessor of its def block, the def slot index will be in the middle of the segment: %vreg11 = [192r,240B:0)[352r,416B:2)[416B,496r:1) 0@192r 1@480B-phi %2@352r A LiveRangeQuery for 480 should return NULL from valueIn() since the PHI value is defined at the block entry, not live in to the block. No test case, future code depends on this functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163971 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-15Port the SSAUpdater-based promotion logic from the old SROA pass to theChandler Carruth
new one, and add support for running the new pass in that mode and in that slot of the pass manager. With this the new pass can completely replace the old one within the pipeline. The strategy for enabling or disabling the SSAUpdater logic is to do it by making the requirement of the domtree analysis optional. By default, it is required and we get the standard mem2reg approach. This is usually the desired strategy when run in stand-alone situations. Within the CGSCC pass manager, we disable requiring of the domtree analysis and consequentially trigger fallback to the SSAUpdater promotion. In theory this would allow the pass to re-use a domtree if one happened to be available even when run in a mode that doesn't require it. In practice, it lets us have a single pass rather than two which was simpler for me to wrap my head around. There is a hidden flag to force the use of the SSAUpdater code path for the purpose of testing. The primary testing strategy is just to run the existing tests through that path. One notable difference is that it has custom code to handle lifetime markers, and one of the tests has been enhanced to exercise that code. This has survived a bootstrap and the test suite without serious correctness issues, however my run of the test suite produced *very* alarming performance numbers. I don't entirely understand or trust them though, so more investigation is on-going. To aid my understanding of the performance impact of the new SROA now that it runs throughout the optimization pipeline, I'm enabling it by default in this commit, and will disable it again once the LNT bots have picked up one iteration with it. I want to get those bots (which are much more stable) to evaluate the impact of the change before I jump to any conclusions. NOTE: Several Clang tests will fail because they run -O3 and check the result's order of output. They'll go back to passing once I disable it again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163965 91177308-0d34-0410-b5e6-96231b3b80d8
