Hi, Richi.
Recently, I am evaluating TSVC performance of GCC:
I found both RISC-V and aarch64 can SLP vectorize it:
https://godbolt.org/z/ssvTxxjeT
Both GCC-13 and trunk GCC can SLP it like LLVM (GCC-12 failed) but with
-fno-vect-cost-model.
I suspect we should adjust Vector COST model (I don't think we should ajust
cost
model in target backend since LLVM by default vectorize such case).
