Chris Lattner d615ded96e Use cute tblgen tricks to make zap handling more powerful. Specifically, ... when the dag combiner simplifies an and mask, notice this and allow those bits to be missing from the zap mask. This compiles Alpha/zapnot4.ll into: sll $16,3,$0 zapnot $0,3,$0 ret $31,($26),1 instead of: ldah $0,1($31) lda $0,-8($0) sll $16,3,$1 and $1,$0,$0 ret $31,($26),1 It would be *really* nice to replace the hunk of code in the AlphaISelDAGToDAG.cpp file that matches (and (srl (x, C), c2) into (SRL (ZAPNOTi)) with a similar pattern, but I've spent enough time poking at alpha. Make andrew will do this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30875 91177308-0d34-0410-b5e6-96231b3b80d8		2006-10-11 05:13:56 +00:00
