2009-07-08Support MDNode forward reference.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75031 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Make the code that updates ScalarEvolution's internal state in responseDan Gohman
to a loop deletion more thorough. Don't prune the def-use tree search at instructions that don't have SCEVs computed, because an instruction with a user that has a computed SCEV may itself lack a computed SCEV. Also, remove loop-related values from the ValuesAtScopes and ConstantEvolutionLoopExitValues maps as well. This fixes a regression in 483.xalancbmk. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75030 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Tell ScalarEvolution to forget a loop before starting to delete it.Dan Gohman
This way ScalarEvolution can examine the loop to determine what state it needs to update, if it chooses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75029 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Checkpoint Thumb2 Instr info work. Generalized base code so that it can be ↵David Goodwin
shared between ARM and Thumb2. Not yet activated because register information must be generalized first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75010 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Mark sublw_cc and subfw_cc as Terminator insns so that they are part of the ↵Sanjiv Gupta
terminator insns for a basic block alongwith branch insns. This way a copy is not getting inserted between cmp and branch during PHIElimination disturbing the status flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74992 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Remove the vicmp and vfcmp instructions. Because we never had a release withNick Lewycky
these instructions, no autoupgrade or backwards compatibility support is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74991 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08eliminate the v[if]cmp versions of these tests, now that [if]cmp+sext works.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74980 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Change these tests to use [fi]cmp+sext instead of v[fi]cmp. NoChris Lattner
functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74979 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08dag combine sext(setcc) -> vsetcc before legalize. To make this safe,Chris Lattner
VSETCC must define all bits, which is different than it was documented to before. Since all targets that implement VSETCC already have this behavior, and we don't optimize based on this, just change the documentation. We now get nice code for vec_compare.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74978 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-07Operand of asm("call") (the callee function) is representedDale Johannesen
as "X" constraint and "P" modifier on x86. Make this work. (Change may not be sufficient to fix it for non-Darwin, but I'm pretty sure it won't break anything.) gcc.apple/asm-block-32.c gcc.apple/asm-block-33.c git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74967 91177308-0d34-0410-b5e6-96231b3b80d8
