test/CodeGen/X86/vec_compare-2.ll: Add explicit -mtriple=i686-linux. llvm-svn: 146152

Don't pull vector sext through both hands of a logical operation, since doing so prevents the fusion of vector sext and setcc into vsetcc. Add a testcase for the above transformation. Fix a bogus use of APInt noticed while tracking this down. llvm-svn: 90423

Fix a bug in the integer-promotion of bitcast operations on vector types. We must not issue a bitcast operation for integer-promotion of vector types, because the location of the values in the vector may be different. llvm-svn: 146150

1. Remove the part of r153848 which optimizes shuffle-of-shuffle into a new shuffle node because it could introduce new shuffle nodes that were not supported efficiently by the target. 2. Add a more restrictive shuffle-of-shuffle optimization for cases where the second shuffle reverses the transformation of the first shuffle. llvm-svn: 154266
