2012-09-18Fix getCommonType in a different way from the way I fixed it whenChandler Carruth
working on FCA splitting. Instead of refusing to form a common type when there are uses of a subsection of the alloca as well as a use of the entire alloca, just skip the subsection uses and continue looking for a whole-alloca use with a type that we can use. This produces slightly prettier IR I think, and also fixes the other failure in the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164146 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-18Add a major missing piece to the new SROA pass: aggressive splitting ofChandler Carruth
FCAs. This is essential in order to promote allocas that are used in struct returns by frontends like Clang. The FCA load would block the rest of the pass from firing, resulting is significant regressions with the bullet benchmark in the nightly test suite. Thanks to Duncan for repeated discussions about how best to do this, and to both him and Benjamin for review. This appears to have blocked many places where the pass tries to fire, and so I'm expect somewhat different results with this fix added. As with the last big patch, I'm including a change to enable the SROA by default *temporarily*. Ben is going to remove this as soon as the LNT bots pick up the patch. I'm just trying to get a round of LNT numbers from the stable machines in the lab. NOTE: Four clang tests are expected to fail in the brief window where this is enabled. Sorry for the noise! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164119 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-17Merge into undefined lanes under -new-coalescer.Jakob Stoklund Olesen
Add LIS::pruneValue() and extendToIndices(). These two functions are used by the register coalescer when merging two live ranges requires more than a trivial value mapping as supported by LiveInterval::join(). The pruneValue() function can remove the part of a value number that is going to conflict in join(). Afterwards, extendToIndices can restore the live range, using any new dominating value numbers and updating the SSA form. Use this complex value mapping to support merging a register into a vector lane that has a conflicting value, but the clobbered lane is undef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164074 91177308-0d34-0410-b5e6-96231b3b80d8

These extra operands are not needed by register allocators using VirtRegRewriter, and RAFast don't need them any longer.
