* Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵Stephen Lin2013-07-13255-1492/+1492
| | | | | | | | | | | debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186258 91177308-0d34-0410-b5e6-96231b3b80d8
* LoopVectorizer: Disallow reductions whose header phi is used outside the loopArnold Schwaighofer2013-07-132-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an outside loop user of the reduction value uses the header phi node we cannot just reduce the vectorized phi value in the vector code epilog because we would loose VF-1 reductions. lp: p = phi (0, lv) lv = lv + 1 ... brcond , lp, outside outside: usr = add 0, p (Say the loop iterates two times, the value of p coming out of the loop is one). We cannot just transform this to: vlp: p = phi (<0,0>, lv) lv = lv + <1,1> .. brcond , lp, outside outside: p_reduced = p[0] + [1]; usr = add 0, p_reduced (Because the original loop iterated two times the vectorized loop would iterate one time, but p_reduced ends up being zero instead of one). We would have to execute VF-1 iterations in the scalar remainder loop in such cases. For now, just disable vectorization.

* LoopVectorize fix: LoopInfo must be valid when invoking utils like SCEVExpander.Andrew Trick2013-07-132-18/+131
| | | | | | | | | | | In general, one should always complete CFG modifications first, update CFG-based analyses, like Dominatores and LoopInfo, then generate instruction sequences. LoopVectorizer was creating a new loop, calling SCEVExpander to generate checks, then updating LoopInfo. I just changed the order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186241 91177308-0d34-0410-b5e6-96231b3b80d8

* Change llvm-ar to use lib/Object.Rafael Espindola2013-07-1210-1212/+376
| | | | | | | | | | | | | | | | | | | | | | This fixes two bugs is lib/Object that the use in llvm-ar found: * In OS X created archives, the name can be padded with nulls. Strip them. * In the constructor, remember the first non special member and use that in begin_children. This makes sure we skip all special members, not just the first one. The change to llvm-ar itself consist of * Using lib/Object for reading archives instead of ArchiveReader.cpp. * Writing the modified archive directly, instead of creating an in memory representation. The old Archive library was way more general than what is needed, as can be seen by the diffstat of this patch. Having llvm-ar using lib/Object now opens the way for creating regular symbol tables for both native objects and bitcode files so that we can use those archives for LTO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186197 91177308-0d34-0410-b5e6-96231b3b80d8
