2009-09-16At iSel time, update DebugLoc based on debug info attached with an instruction.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82077 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-16Add a new pass for doing late hoisting of floating-point and vectorDan Gohman
constants out of loops. These aren't covered by the regular LICM pass, because in LLVM IR constants don't require separate instructions. They're not always covered by the MachineLICM pass either, because it doesn't know how to unfold folded constant-pool loads. This is somewhat experimental at this point, and off by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82076 91177308-0d34-0410-b5e6-96231b3b80d8

we have MCInstPrinter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82006 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-16Big change #1 for personality function references:Chris Lattner
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding fields from MAI: they aren't part of the asm syntax, they are related to the structure of the object file. To replace their functionality, add a new TLOF::getSymbolForDwarfGlobalReference method which asks targets to decide how to reference a global from EH in a pc-relative way. The default implementation just returns the symbol. The default darwin implementation references the symbol through an indirect $non_lazy_ptr stub. The bizarro x86-64 darwin specialization handles the weird "foo@GOTPCREL+4" hack. DwarfException.cpp now uses this to emit the reference to the symbol in the right way, and this also eliminates another horrible hack from DwarfException.cpp: - if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL")) - O << "-" << MAI->getPCSymbol(); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81991 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-16inline AsmPrinter::getCurrentFunctionEHName into its only caller.Chris Lattner

2009-09-16Eliminate AsmPrinter::EmitExternalGlobal, inlining its (now)Chris Lattner
one implementation into its one caller. This eliminates a totally awesome and gratuitous hack where we casted a Function* to GlobalVariable*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81967 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-16eliminate the horrid AsmPrinter::getGlobalLinkName method, inliningChris Lattner
it into all of its call sites and simplifying them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81962 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81946 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-15Better solution for tracking both the original alignment of the access, and ↵Nate Begeman
the current alignment based on the source value offset. This avoids increasing the size of mem nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15Another try at early partial coalescing. Identity phi source copies (their ↵Evan Cheng
sources are defined by phi join def) are coalesced. And the phi join copy is backward copy propagated into the other copies. Still miscompiling some tests. :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81849 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81819 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15Substantially speed up combiner-aa in the following ways:Nate Begeman
1. Switch from an std::set to a SmallPtrSet for visited chain nodes. 2. Do not force the recursive flattening of token factor nodes, regardless of use count. 3. Immediately process newly created TokenFactor nodes. Also, improve combiner-aa by teaching it that loads to non-overlapping offsets of relatively aligned objects cannot alias. These changes result in a >5x speedup for combiner-aa on most testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81816 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15Teach the legalizer to propagate the original alignment of loads and store whenNate Begeman
it splits them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81815 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15Add an "original alignment" field to load and store nodes. This enables theNate Begeman
DAG Combiner to disambiguate chains for loads and stores of types which are broken up by the Legalizer into smaller pieces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81813 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-14Add early coalescing to liveintervals. This is work in progress and is known ↵Evan Cheng
to miscompute some tests. Read it at your own rish, I have aged 10 year while writing this. The gist of this is if source of some of the copies that feed into a phi join is defined by the phi join, we'd like to eliminate them. However, if any of the non-identity source overlaps the live interval of the phi join then the coalescer won't be able to coalesce them. The early coalescer's job is to eliminate the identity copies by partially-coalescing the two live intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81796 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-14Pull the creation of the "RewindFunction" function out of the loop. It's onlyBill Wendling
created once, so shouldn't be stuck in the middle of the loop. Also early exit if there are no uses of UnwindInst in the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81785 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-14Change MCAsmStreamer to take an MCInstPrinter instead of a Chris Lattner
full AsmPrinter, and change TargetRegistry to keep track of registered MCInstPrinters. llvm-mc is still linking in the entire target foo to get the code emitter stuff, but this is an important step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81754 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-13replace printBasicBlockLabel with EmitBasicBlockStart,Chris Lattner
now that printBasicBlockLabel is only used for starting a MBB. This allows elimination of a bunch of arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81684 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-13convert some uses of printBasicBlockLabel to use GetMBBSymbolChris Lattner
instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81677 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-12devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden.Chris Lattner
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that we only have one place that decides what to name bb labels. Hopefully various clients of printBasicBlockLabel can start using GetMBBSymbol instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81652 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-11Fix PR4948 (and a leak): by not destroying the DwarfExceptionDuncan Sands
object, the timer it creates was not being deleted. Since the timer belonged to a static timer group, the timer group would be destroyed on shutdown, and would notice and complain that not all timers it contained were destroyed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81533 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-10Revert part of my r81424 patch. I removed what looked like superfluous paddingBill Wendling
from the exception tables. However, Duncan explained why it's a can of worms to do it the GCC way. I went back to doing it the LLVM way and added Duncan's explanation so that I don't do this again in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81434 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-10Don't hardcode the TType format size. In fact, rework the code so that it's moreBill Wendling
like what GCC outputs. The mysterious code to insert padding wasn't in GCC at all. I modified the TType base offset code to calculate the offset like GCC does, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81424 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-10Remove the "#if 0" that Noone loved. It wasn't really necessary, because theBill Wendling
code within it was the same inside and out. There's still a problem of the TypeInfoSize should be the size of the TType format encoding (at least that's what GCC thinks it should be). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81417 91177308-0d34-0410-b5e6-96231b3b80d8
