[LLVMdev] bitwise AND selector node not commutative?
Using the Thumb-2 target we see that ORN ( a | ^b) and BIC (a & ^b) have similar patterns, as we would expect: defm t2BIC : T2I_bin_irs<"bic", BinOpFrag<(and node:$LHS, (not node: $RHS))>>; defm t2ORN : T2I_bin_irs<"orn", BinOpFrag<(or node:$LHS, (not node: $RHS))>>; Compiling the following three works as expected: %tmp1 = xor i32 4294967295, %b ; %tmp2 = or i32 %a, %tmp1 --...
