vls loop. It's not big issue and not high priority for me. Replied Message FromRobin DappDate01/12/2024 18:10 ToJuzhe-Zhong,gcc-patches@gcc.gnu.org Ccrdapp@gmail.com,kito.ch...@gmail.com,kito.ch...@sifive.com,jeffreya...@gmail.comSubjectRe: [PATCH V3] RISC-V: Adjust scalar_to_vec cost

Yes, thanks!
Btw out of curiosity, did you see why we actually fail to
optimize away the VLA loop? We should open a bug for that
I suppose.

1. Introduce vector regmove new tune info.
2. Adjust scalar_to_vec cost in add_stmt_cost.
We will get optimal codegen after this patch with -march=rv64gcv_zvl256b:
lui a5,%hi(a)
li a4,19
sb a4,%lo(a)(a5)
li a0,0
ret
Tested on both
