* Implement enough of the missing instalias support to getChris Lattner2010-11-012-3/+33
| | | | | | | | | | | | | | | | | | | | aliases installed and working. They now work when the matched pattern and the result instruction have exactly the same operand list. This is now enough for us to define proper aliases for movzx and movsx, implementing rdar://8017633 and PR7459. Note that we do not accept instructions like: movzx 0(%rsp), %rsi GAS accepts this instruction, but it doesn't make any sense because we don't know the size of the memory operand. It could be 8/16/32 bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117901 91177308-0d34-0410-b5e6-96231b3b80d8
