Jakob Stoklund Olesen 980daea857 Fix Bug 4657: register scavenger asserts with subreg lowering ... When LowerSubregsInstructionPass::LowerInsert eliminates an INSERT_SUBREG instriction because it is an identity copy, make sure that the same registers are alive before and after the elimination. When the super-register is marked <undef> this requires inserting an IMPLICIT_DEF instruction to make sure the super register is live. Fix a related bug where a kill flag on the inserted sub-register was not transferred properly. Finally, clear the undef flag in MachineInstr::addRegisterKilled. Undef implies dead and kill implies live, so they cant both be valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77989 91177308-0d34-0410-b5e6-96231b3b80d8		2009-08-03 20:08:18 +00:00
