This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now). llvm-svn: 82214

| | | | | | | | | | | 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.

* Big change #1 for personality function references:Chris Lattner2009-09-161-19/+45
| | | | | | | | | | | | | | | | | | | | | | | | 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(); llvm-svn: 81991
* inline AsmPrinter::getCurrentFunctionEHName into its only caller.Chris Lattner2009-09-162-11/+6

* Eliminate AsmPrinter::EmitExternalGlobal, inlining its (now)Chris Lattner2009-09-162-8/+1
| | | | | | | | one implementation into its one caller. This eliminates a totally awesome and gratuitous hack where we casted a Function* to GlobalVariable*. llvm-svn: 81967

| | | | | | it into all of its call sites and simplifying them. llvm-svn: 81962

| | | | | | | move MachineFunctionInfo virtual method out of line to give it a home. llvm-svn: 81940

* Better solution for tracking both the original alignment of the access, and ↵Nate Begeman2009-09-153-44/+33
| | | | | | | | the current alignment based on the source value offset. This avoids increasing the size of mem nodes. llvm-svn: 81897
* Another try at early partial coalescing. Identity phi source copies (their ↵Evan Cheng2009-09-151-58/+56
| | | | | | | | 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. :-( llvm-svn: 81849
* Remove incorrect CSE code from r81813.Nate Begeman2009-09-151-2/+0
| | | | llvm-svn: 81819
* Substantially speed up combiner-aa in the following ways:Nate Begeman2009-09-151-33/+69
| | | | | | | | | | | | | | 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. llvm-svn: 81816

* Add early coalescing to liveintervals. This is work in progress and is known ↵Evan Cheng2009-09-141-24/+164
| | | | | | | | 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. llvm-svn: 81796
* Pull the creation of the "RewindFunction" function out of the loop. It's onlyBill Wendling2009-09-141-14/+25
| | | | | | | 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. llvm-svn: 81785
* PIC16 does allow colon after MBB labels, simplify EmitBasicBlockStart.Chris Lattner2009-09-141-5/+2
| | | | llvm-svn: 81755
* Change MCAsmStreamer to take an MCInstPrinter instead of a Chris Lattner2009-09-141-1/+2
| | | | | | | | | | | 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. llvm-svn: 81754
* kill off the last use of TRI::AsmName.Chris Lattner2009-09-131-1/+1
| | | | llvm-svn: 81727
* eliminate an extraneous use of TRI::getAsmName in a comment.Chris Lattner2009-09-131-1/+1

* remove MAI::JumpTableSpecialLabelPrefix now that MAI Chris Lattner2009-09-131-4/+4

* replace printBasicBlockLabel with EmitBasicBlockStart,Chris Lattner2009-09-131-14/+11
| | | | | | | now that printBasicBlockLabel is only used for starting a MBB. This allows elimination of a bunch of arguments. llvm-svn: 81684
* convert some uses of printBasicBlockLabel to use GetMBBSymbolChris Lattner2009-09-131-8/+7
