* Two changes:Chris Lattner2007-03-202-13/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | 1) codegen a shift of a register as a shift, not an LEA. 2) teach the RA to convert a shift to an LEA instruction if it wants something in three-address form. This gives us asm diffs like: - leal (,%eax,4), %eax + shll $2, %eax which is faster on some processors and smaller on all of them. and, more interestingly: - movl 24(%esi), %eax - leal (,%eax,4), %edi + movl 24(%esi), %edi + shll $2, %edi Without #2, #1 was a significant pessimization in some cases. This implements CodeGen/X86/shift-codegen.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35204 91177308-0d34-0410-b5e6-96231b3b80d8
