Dan Gohman 223942a420 Remove the code from the scheduler that commuted two-address ... instructions to avoid copies, because TwoAddressInstructionPass also does this optimization. The scheduler's version didn't account for live-out values, which resulted in spurious commutes and missed opportunities. Now, TwoAddressInstructionPass handles all the opportunities, instead of just those that the scheduler missed. The result is usually the same, though there are occasional trivial differences resulting from the avoidance of spurious commutes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61611 91177308-0d34-0410-b5e6-96231b3b80d8		2009-01-03 18:01:46 +00:00

MachineModuleInfo.h	Today the front-ends (llvm-gcc and clang) generate multiple llvm.dbg.compile_units to identify source file for various debug entities. Each llvm.dbg.compile_unit matches one file on the disk. However, the backend only supports one DW_TAG_compile_unit per .o file. The backend selects first compile_unit from the vector to construct DW_TAG_compile_unit entry, which is not correct in all cases.	2008-12-17 22:39:29 +00:00
