Chris Lattner 9ad5915559 SIGN_EXTEND_INREG does not demand its top bits. Give SimplifyDemandedBits ... a chance to hack on it. This compiles: int baz(long long a) { return (short)(((int)(a >>24)) >> 9); } into: _baz: slwi r2, r3, 8 srwi r2, r2, 9 extsh r3, r2 blr instead of: _baz: srwi r2, r4, 24 rlwimi r2, r3, 8, 0, 23 srwi r2, r2, 9 extsh r3, r2 blr This implements CodeGen/PowerPC/sign_ext_inreg1.ll llvm-svn: 36212		2007-04-17 19:03:21 +00:00
