Chris Lattner 588bbbffa1 Improve and elimination. On PPC, for: ... bool %test(int %X) { %Y = and int %X, 8 %Z = setne int %Y, 0 ret bool %Z } we now generate this: rlwinm r2, r3, 0, 28, 28 srwi r3, r2, 3 instead of this: rlwinm r2, r3, 0, 28, 28 srwi r2, r2, 3 rlwinm r3, r2, 0, 31, 31 I'll leave it to Nate to get it down to one instruction. :) --------------------------------------------------------------------- git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21391 91177308-0d34-0410-b5e6-96231b3b80d8		2005-04-21 06:28:15 +00:00
