2010-07-24Whether function-local or not, a MDNode may reference a Function in which caseNick Lewycky

2010-07-14Extend SimplifyCFG's common-destination folding heuristic to allow a singleOwen Anderson
"bonus" instruction to be speculatively executed. Add a heuristic to ensure we're not tripping up out-of-order execution by checking that this bonus instruction only uses values that were already guaranteed to be available. This allows us to eliminate the short circuit in (x&1)&&(x&2). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108351 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-25The hasMemory argument is irrelevant to how the argumentDale Johannesen

seeded in value map. This is not limited to function local metadata. Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes.
