2011-05-27My attempt at fixing the leak reported by the valgrind buildbots. Valgrind willCharles Davis
still report leaks, but they're spurious now. Valgrind cannot peer into std::vector objects--or any dynamic array, for that matter--because it doesn't know how big the array is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132174 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-26Fix warning about || and && without explicit grouping.Chandler Carruth
This looks like it flagged an actual bug. Devang, please review. I added the parentheses that change behavior, but make the behavior more closely match commit log's intent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132165 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-26Test .seh_startchained and .seh_endchained parsing.Charles Davis
Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with chained unwind areas exposed by the test that were related to this. The ChainedParent field had the wrong address, because when the chained unwind info was added, the addresses shifted around. Now we store the pointers to the structures, which are now allocated from the MC heap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132106 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-26indvars: incremental fixes for -disable-iv-rewrite and testcases.Andrew Trick
Use a proper worklist for use-def traversal without holding onto an iterator. Now that we process all IV uses, we need complete logic for resusing existing derived IV defs. See HoistStep. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132103 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Add a RAGreedy::canEvict function.Jakob Stoklund Olesen
This doesn't change functionality (much), but it allows for a more fine-grained eviction policy. The current policy only compares spill weights, and that is not always the best thing to do. Spill weights are designed to serve linear scan, and they don't consider live range splitting. Add a mechanism so canEvict() can request that a live range be evicted and split/spilled. This is to avoid infinite eviction loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132101 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Rewrite fast-isel integer cast handling to handle more cases, and to be ↵Eli Friedman
simpler and more consistent. The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts). rdar://9437928 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132099 91177308-0d34-0410-b5e6-96231b3b80d8
