...case is a simple integer comparison routine, similar to what qsort would take to sort an integer array. I think llvm should be taking advantage of the preceding instruction and not placing the similar instruction again. rev.208525, optimization level 3. Yuri --- C-style original code --- int mycmp (int i1, int i2) { if (i1<i2) { return -1; } else if (i1>i2) { return 1; } return 0; } --- llvm code --- define i32 @mycmp(i32, i32) #0 { lbl0: %icmp.ULT = icmp ult i32 %0, %1 br i1 %icmp.ULT, label %lbl1, label %lbl2 lbl1: %merge = phi i32 [ -1,...
