Patch by David Meyer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151575 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-27Fix for PR12090: clear def maps of aliases when visiting a copy. e.g.Evan Cheng
%S5<def> = COPY %S0<kill> First clear def map of Q1, etc. No small test case available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151574 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-27ARM BL/BLX instruction fixups should use relocations.Jim Grosbach
We on the linker to resolve calls to the appropriate BL/BLX instruction to make interworking function correctly. It uses the symbol in the relocation to do that, so we need to be careful about being too clever. To enable this for ARM mode, split the BL/BLX fixup kind off from the unconditional-branch fixups. rdar://10927209 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151571 91177308-0d34-0410-b5e6-96231b3b80d8

After the SlotIndex slot names were updated, it is possible to apply stricter checks to live intervals. Also treat bundles as bags of operands when checking live intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151531 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-27Add a MachineOperand iterator class.Jakob Stoklund Olesen
The MIOperands iterator can visit operands on a single instruction, or all operands in a bundle. This simplifies code like the register allocator that treats bundles as a set of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151529 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-27The value numbering function is recursive, so it is possible for multiple newDuncan Sands
value numbers to be assigned when calculating any particular value number. Enhance the logic that detects new value numbers to take this into account, for a tiny compile time speedup. Fix a comment typo while there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151522 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-27When performing a conditional branch depending on the value of a comparisonDuncan Sands
%cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and with "false" under the false edge. This change enhances this to replace the negated compare (A!=B) with "false" under the true edge and "true" under the false edge.
