2011-09-14Hoist back-copies to the least busy dominator.Jakob Stoklund Olesen
When a back-copy is hoisted to the nearest common dominator, keep looking up the dominator tree for a less loopy dominator, and place the back-copy there instead. Don't do this when a single existing back-copy dominates all the others. Assume the client knows what he is doing, and keep the dominating back-copy. This prevents us from hoisting back-copies into loops in most cases. If a value is defined in a loop with multiple exits, we may still hoist back-copies into that loop. That is the speed/size tradeoff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139698 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-14One more patch towards JIT support for Mips.Bruno Cardoso Lopes
- Add TSFlags for the instruction formats. The idea here is to use as much encoding as possible from getBinaryCodeForInstr, and having TSFLags formats for that would make it easier to encode most part of the instructions (since Mips encodings are pretty straightforward) - Improve the mips mechanism for compilation callback - Add Mips specific code for invalidating the instruction cache - Next patch will address wrong tablegen encoding Commit msg added by my own but the patch is from Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139688 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-14Teach the foldable tables about 128-bit AVX instructions and make theBruno Cardoso Lopes
alignment check for 256-bit classes more strict. There're no testcases but we catch more folding cases for AVX while running single and multi sources in the llvm testsuite. Since some 128-bit AVX instructions have different number of operands than their SSE counterparts, they are placed in different tables. 256-bit AVX instructions should also be added in the table soon. And there a few more 128-bit versions to handled, which should come in the following commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139687 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-14Object: make the following changes into SymbolRefBenjamin Kramer
- Add enum SymbolType and function getSymbolType() - Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions. - Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address. - Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.

2011-09-13Distinguish complex mapped values from forced recomputation.Jakob Stoklund Olesen
When a ParentVNI maps to multiple defs in a new interval, its live range may still be derived directly from RegAssign by transferValues(). On the other hand, when instructions have been rematerialized or hoisted, it may be necessary to completely recompute live ranges using LiveRangeCalc::extend() to all uses. Use a bit in the value map to indicate that a live range must be recomputed. Rename markComplexMapped() to forceRecompute(). This fixes some live range verification errors when -split-spill-mode=size hoists back-copies by recomputing source ranges when RegAssign kills can't be moved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139660 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Implement -split-spill-mode=size.Jakob Stoklund Olesen
Whenever the complement interval is defined by multiple copies of the same value, hoist those back-copies to the nearest common dominator. This ensures that at most one copy is inserted per value in the complement inteval, and no phi-defs are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139651 91177308-0d34-0410-b5e6-96231b3b80d8
