Benjamin Kramer 1db071f0da Teach instcombine to transform ... (X >s -1) ? C1 : C2 and (X <s 0) ? C2 : C1 into ((X >>s 31) & (C2 - C1)) + C1, avoiding the conditional. This optimization could be extended to take non-const C1 and C2 but we better stay conservative to avoid code size bloat for now. for int sel(int n) { return n >= 0 ? 60 : 100; } we now generate sarl $31, %edi andl $40, %edi leal 60(%rdi), %eax instead of testl %edi, %edi movl $60, %ecx movl $100, %eax cmovnsl %ecx, %eax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107866 91177308-0d34-0410-b5e6-96231b3b80d8		2010-07-08 11:39:10 +00:00
