Evan Cheng e6f350d755 Turn a 2-address instruction into a 3-address one when it's profitable even if the two-address operand is killed. ... e.g. %reg1024<def> = MOV r1 %reg1025<def> = ADD %reg1024, %reg1026 r0 = MOV %reg1025 If it's not possible / profitable to commute ADD, then turning ADD into a LEA saves a copy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68065 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-30 21:34:07 +00:00
