Environment:

RSD version: bd7c5c1


Bug Description:

There is an instruction fdiv.s fs3, fa5, fa4, where fa5=0x3292f14b and fa4=0x71da37da .

After the fdiv.s instruction, fflags.UF flag in RSD maintains 0 . However, fflags.UF flag in spike is set to 1 .


It seems that RSD updates fflags.UF incorrectly?
