Re: [PATCH v1] RISC-V: Support RVV VFDIV and VFRDIV rounding mode intrinsic API

[juzhe.zhong]

[-- Attachment #1: Type: text/plain, Size: 8898 bytes --]

I am considering whether it is better to have multiple macro define for FRM ?

like:

DECLARE_FRM_FUNCTION_BASE (NAME)\
  extern const function_base *const NAME;
  extern const function_base *const NAME##_frm;

DECLARE_FRM_FUNCTION (NAME, ....)\
  DEF_RVV_FUNCTION (NAME##_frm, alu, ....);
  DEF_RVV_FUNCTION (NAME##_frm, alu_frm,....);


I am not sure. I would rather wait for kito's more comments.
