2013-04-24LoopVectorizer: Bail out if we don't have datalayout we need itArnold Schwaighofer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180195 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24Revert r180189.Rafael Espindola
This should bring the ppc bots back. I will try to write a test that would have found the problem on a little endian system too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180194 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24MI Sched: eliminate local vreg copies.Andrew Trick
For now, we just reschedule instructions that use the copied vregs and let regalloc elliminate it. I would really like to eliminate the copies on-the-fly during scheduling, but we need a complete implementation of repairIntervalsInRange() first. The general strategy is for the register coalescer to eliminate as many global copies as possible and shrink live ranges to be extended-basic-block local. The coalescer should not have to worry about resolving local copies (e.g. it shouldn't attemp to reorder instructions). The scheduler is a much better place to deal with local interference. The coalescer side of this equation needs work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180193 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24Register Coalescing: add a flag to disable rescheduling.Andrew Trick
When MachineScheduler is enabled, this functionality can be removed. Until then, provide a way to disable it for test cases and designing MachineScheduler heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180192 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-24Use a pointer as the relocation iterator.Rafael Espindola
Since the relocation iterator walks only the relocations in one section, we can just use a pointer and avoid fetching information about the section at every reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180189 91177308-0d34-0410-b5e6-96231b3b80d8

VSETCC without first checking the target's vector boolean contents. This exposed an issue with PowerPC AltiVec where it appears it was setting the wrong vector boolean contents.

2013-04-23Add some constraints to use of 'returned':Stephen Lin
1) Disallow 'returned' on parameter that is also 'sret' (no sensible semantics, as far as I can tell). 2) Conservatively disallow tail calls through 'returned' parameters that also are 'zext' or 'sext' (for consistency with treatment of other zero-extending and sign-extending operations in tail call position detection...can be revised later to handle situations that can be determined to be safe). This is a new attribute that is not yet used, so there is no impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180118 91177308-0d34-0410-b5e6-96231b3b80d8
