Jatin Bhateja 84f0cdcd15 [X86] Improvement in CodeGen instruction selection for LEAs (re-applying post required revision changes.) ... Summary: 1/ Operand folding during complex pattern matching for LEAs has been extended, such that it promotes Scale to accommodate similar operand appearing in the DAG. e.g. T1 = A + B T2 = T1 + 10 T3 = T2 + A For above DAG rooted at T3, X86AddressMode will no look like Base = B , Index = A , Scale = 2 , Disp = 10 2/ During OptimizeLEAPass down the pipeline factorization is now performed over LEAs so that if there is an opportunity then complex LEAs (having 3 operands) could be factored out. e.g. leal 1(%rax,%rcx,1), %rdx leal 1(%rax,%rcx,2), %rcx will be factored as following leal 1(%rax,%rcx,1), %rdx leal (%rdx,%rcx) , %edx 3/ Aggressive operand folding for AM based selection for LEAs is sensitive to loops, thus avoiding creation of any complex LEAs within a loop.
