* Extend SimplifyCFG's common-destination folding heuristic to allow a singleOwen Anderson2010-07-141-5/+67
| | | | | | | | | | "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). llvm-svn: 108351

* If a metadata operand is seeded in value map and the metadata should also be ↵Devang Patel2010-06-221-13/+34
| | | | | | | | | | | 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. For example, Checking to see if we can delete global inits: Unknown constant! UNREACHABLE executed at /d/g/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp:904! llvm-svn: 106592
