Rework getPersonalityIndex slightly - 0 is now a valid and not-NULL personality function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81982 91177308-0d34-0410-b5e6-96231b3b80d8

If we're emitting additional CIEs due to personality functions don't emit the default one. Explicitly check for the NULL CIE later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81702 91177308-0d34-0410-b5e6-96231b3b80d8

Make the augmentation size and next set of bytes agree on size, and make the reference pointer size as it should be. Fixes an abort on a testcase derived from libunwind's personality test in 64-bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81701 91177308-0d34-0410-b5e6-96231b3b80d8

When widening a vector load, use the correct chain. This fixes PR4891. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81411 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-08Merge 81204 from mainline (with minor tweak).Tanya Lattner
When remat'ing and destination virtual register has a sub-register index. Make sure the sub-register class matches the register class of the remat'ed instruction definition register class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81270 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-04Merge 80872 from mainline.Tanya Lattner
Fixed a test that ensures the LocalRewriter does not attempt to avoid reloads by reusing clobbered registers. This was causing issues in 256.bzip2 when compiled with PIC for a while (starting at r78217), though the problem has since been masked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81032 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-31Merge from mainline.Tanya Lattner
When undoing a reuse in ReuseInfo::GetRegForReload, check if it was only a sub-register being used. The MachineOperand::getSubReg() method is only valid for virtual registers, so we have to recover the sub-register index manually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@80552 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-22Ease contention on this lock by noticing that all writes to the VTs array willOwen Anderson
be of (dynamically) constant values, so races on it are immaterial. We just need to ensure that at least one write has completed before return the pointer into it. With this change, parllc exhibits essentially no overhead on 403.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79708 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-18Simplify RegScavenger::FindUnusedReg.Jakob Stoklund Olesen
- Drop the Candidates argument and fix all callers. Now that RegScavenger tracks available registers accurately, there is no need to restict the search. - Make sure that no aliases of the found register are in use. This was a potential bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79369 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-18Make tail merging handle blocks with repeated predecessors correctly, andDan Gohman
remove RemoveDuplicateSuccessor, as it is no longer necessary, and because it breaks assumptions made in MachineBasicBlock::isOnlyReachableByFallthrough. Convert test/CodeGen/X86/omit-label.ll to FileCheck and add a testcase for PR4732. test/CodeGen/Thumb2/thumb2-ifcvt2.ll sees a diff with this commit due to it being bugpoint-reduced to the point where it doesn't matter what the condition for the branch is. Add some more interesting code to test/CodeGen/X86/2009-08-06-branchfolder-crash.ll, which is the testcase that originally motivated the RemoveDuplicateSuccessor code, to help verify that the original problem isn't being re-broken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79338 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Make AsmStreamer maintain a notion of the current section, pushing it up ↵Chris Lattner
from the MCAsmStreamer. Based on this, eliminate the current section from AsmPrinter. While I'm at it, clean up the last of the horrible "switch to null section" stuff and add an assert. This change is in preparation for completely eliminating asmprinter::switchtosection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79324 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18add a horrible hack to the dwarf printer. It looks like mingw is not specifyingChris Lattner
an EHFrame section, so we just emit ehframe data into a random section. This is clearly bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79323 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-18turn this conditional into something humans might actuallyChris Lattner
be able to understand ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79311 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17cleanups per review. Mostly cosmetic, plus use SmallVector in place of ↵Jim Grosbach

2009-08-17Move the sjlj exception handling conversions to a back-end pass where theyJim Grosbach
more properly belong. This allows removing the front-end conditionalized SJLJ code, and cleans up the generated IR considerably. All of the infrastructure code (calling _Unwind_SjLj_Register/Unregister, etc) is added by the SjLjEHPrepare pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79250 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17Extend the instruction itinerary model to include the ability to indicate ↵David Goodwin
the def and use cycle for each operand. This additional information is optional, so existing itineraries do not need to be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79247 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17the MinPad argument to PadToColumn only really makes sense to be 1,Chris Lattner
