Byte-wide stores aren't coalesced if interspersed with other stores
...(SLP in this case) happen to
move instructions *within the same basic block* out of the way, these
stores don't get coalesced? And then only if the either the
optimization pipeline is run again, or if instruction selection can do
so?
On IRC Roman Lebedev pointed out https://reviews.llvm.org/D48725 which
might address this indirectly. But I'm somewhat doubtful that that's
the most straightforward way to optimize this kind of code?
