Subject: [PATCH 1/4] [RISCV] Account for factor in interleave memory op costs
Currently we cost an interleaved memory op as if it were a load/store of the widened vector type.
However this doesn't take into account that we'll most likely need to perform at least Factor uops because we're writing/reading from Factor number of registers.
E.g. Today an i8 VF=2 Factor=8 interleave is costed as a single LMUL=1 op with +zvl128b, because the widened type is <16 x i8>.
This changes it to be calculated as <2 x i8> * Factor=8, i.e. 8 LMUL=1 ops.
Thankfully the FIXME about illegal vectors seems to have been fixed in #100436, and even then I think the LT.first should have been multiplied, not added.
Note we still have a quirk where the loop vectorizer will happily emit interleaved accesses for what could be strided accesses, because the costs are break-even in LoopVectorizationCostModel::setCostBasedWideningDecision:
void f(int8_t* a, int n) {
for (int i = 0; i < n; i++) {
a[i * 2] += 1;
}
}
vsetvli t1, zero, e8, m2, ta, ma
vlseg2e8.v v24, (t0)
vadd.vi v24, v24, 1
vsse8.v v24, (a6), a5
I think we may need to either adjust the cost or add a hook to get the loop vectorizer to s
