Jakob Stoklund Olesen 351c8818f2 Handle <undef> operands in TwoAddressInstructionPass. ... When the source register to a 2-addr instruction is undefined, there is no need to attempt any transformations - simply replace the source register with the destination register. This also comes up when lowering IMPLICIT_DEF instructions - make sure the <undef> flag is moved to the new partial register def operand: %vreg8<def> = INSERT_SUBREG %vreg9<undef>, %vreg0<kill>, sub_16bit rewrite undef: %vreg8<def> = INSERT_SUBREG %vreg8<undef>, %vreg0<kill>, sub_16bit convert to: %vreg8:sub_16bit<def,read-undef> = COPY %vreg0<kill> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159120 91177308-0d34-0410-b5e6-96231b3b80d8		2012-06-25 03:27:12 +00:00
