* Add a new pass for doing late hoisting of floating-point and vectorDan Gohman2009-09-161-1/+6
| | | | | | | | | | | | 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

* 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(); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81991 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81816 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81796 91177308-0d34-0410-b5e6-96231b3b80d8
