plementation is more reasonable, I will send a separate patch to
adjust integer ternary autovec patterns.

But it causes to many issues. I do many tries turns out only the current

Can you describe more concretely what failed?
Offhand I can't think of a reas

Also, fix attribute bug of floating-point ternary operations in vector.md.
gcc/ChangeLog:
* config/riscv/autovec.md (fma4): New pattern.
(*fma): Ditto.

Hi Juzhe,
LGTM apart from a tiny nit:

Seems like you copied this from the non-fp ternary part but the
rest of the file us
