--- Comment #30 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- (In reply to wilco from comment #29) > Combine could help with > merging 2 loads/stores into a single instruction. No, combine works strictly on dataflow dependencies. Two stores cannot be dataflow related so won't be combined. Loads would only be dataflow related if both loads fed into *exactly* one data-processing instruction after the split. That's unlikely to happen so I very much dobut it would happen there either.
