> This patch is adding rounding mode operand and FRM_REGNUM dependency
> into floating-point instructions.
>
> The floating-point instructions we added FRM and rounding mode operand:
> 1. vfadd/vfsub
> 2. vfwadd/vfwsub
> 3. vfmul
> 4. vfdiv
> 5. vfwmul
> 6. vfwmacc/vfwnmacc/vfwmsac/vfwnmsac
> 7. vfsqrt7/vfrec7
> 8. floating-point conversions.
> 9. floating-point reductions.
>
> The floating-point instructions we did NOT add FRM and rounding mode
> operand:
> 1. vfsqrt/vfneg
> 2. vfmin/vfmax
> 3. comparisons
> 4. vfclass
> 5. vfsgnj/vfsgnjn/vfsgnjx
> 6. vfmerge
> 7. vfmv.v.f
>
> TODO: floating-point ternary: FRM and rounding mode operand should be
> added but
> they are not added in this patch since it will exceed the number of
> operands can
> be handled in optabs.cc. Will add it the next patch.
