Chris Lattner 50af16a97b Simplify handling of shifts to be the same as we do for adds. Add support ... for (X * C1) + (X * C2) (where * can be mul or shl), allowing us to fold: Y+Y+Y+Y+Y+Y+Y+Y into %tmp.8 = shl long %Y, ubyte 3 ; <long> [#uses=1] instead of %tmp.4 = shl long %Y, ubyte 2 ; <long> [#uses=1] %tmp.12 = shl long %Y, ubyte 2 ; <long> [#uses=1] %tmp.8 = add long %tmp.4, %tmp.12 ; <long> [#uses=1] This implements add.ll:test25 Also add support for (X*C1)-(X*C2) -> X*(C1-C2), implementing sub.ll:test18 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17704 91177308-0d34-0410-b5e6-96231b3b80d8		2004-11-13 19:50:12 +00:00
