I would suggest using `-march=rv64gcv` or `-march=rv64gcv_zvfh_zfh`?
Just zfh is not meaningful I think.

[PATCH] RISC-V: Enable vec_init testsuite for RVV VLA vectorization

2023-08-27 Thread Juzhe-Zhong 
Hi, this patch is enabling vec_init for RVV VLA vectorization since we have 
almost
support all RVV-related features to the middle-end loop vectorizer.
