Hi@bryan_hong

you can check the "Disassembly" to see the difference.

by the way, if you already enabled FPU but it still fails, you can check "Optimization Level" is set to None or not, I found that this option has an impact on the FPU settings.

Hi@bryan_hong

I only tested the optimization options.
I did't test these options,but I think this should not affect the FPU.

Dear @Senlent

I think it would be better to not tell customer about that 4 optimazation.
