This can be done only with moves which theoretically will optimize better later. Although this transform increases the instruction count, it should be code size / cycle count neutral in the worst VALU case. It also seems to slightly improve a couple of testcases due to other DAG combines this exposes. This is probably slightly worse for the SALU case, so it might be better to handle this during moveToVALU, although then you lose some simplifications like the load width reducing in the simple testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242177 91177308-0d34-0410-b5e6-96231b3b80d8 |
