Benjamin Kramer b619dd5d5b X86: Shrink certain forms of movsx. ... In particular: movsbw %al, %ax --> cbtw movswl %ax, %eax --> cwtl movslq %eax, %rax --> cltq According to Intel's manual those have the same performance characteristics but come with a smaller encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186174 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-12 18:06:44 +00:00
