e.g. for dotproduct case, with this patch, despite there being no data dependencies, compiler literally does 4 `VFMADD*SS` in the loop with different xmm registers. Instead of just doing 1 `VFMADD*PS` with one xmm register containing the 4 floats. Seems dumb to me. -- This is an automated message from the Apache Git Service.
