From: Pan Li <[email protected]>
The vwaddu and vwsubu combine pattern should take plus/minus
instead of any_widen_binop. This PATCH would like to fix it.
The below test suites are passed for this patch series.
* The rv64gcv fully regression test.
gcc/ChangeLog:
* config/riscv/autovec-opt.md: Take concrete op instead
of any_widen_binop for vwaddu/vwsubu wx combine.
