Casts taking a constant expression (generally derived from a global variable address) as an operand are not profitable to CSE because they appear as subexpressions in the instruction sequence generated by the LowerTypeTests pass which is expected to pattern match to the rotate instruction. These casts are expected to be code generated into the instruction's immediate operand, so there is no benefit to hoisting them anyway. _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
