I think we'll have to write some new code for this.
Easiest might be:
(1) shift left to convert bfloat16 to fl

What do you mean by re-use the float32 interface? Isn't bfloat16 going

What do you mean by re-use the float32 interface? Isn't bfloat16 going
to be pretty much the same as float

I am doing bfloat16 support on QEMU.
Once I tried to reuse float32 interface, but I couldn't properly process
rounding in some insns like fadd.
What's your opinion about it? Should I expand the fpu/softfloat?
