[DiscordArchive] my bad, wanted to say FPU registers, not FPU stack.

ghidra has this really weird attitude of flipping the code flow

Also in your case it inlines ftol2 code in case your CPU doesn't support SSE

This is how it looks in IDA:
```cpp
int __usercall _ftol2_sse@<eax>(double a1@<st0>)
{
if ( s_cpuSupportSSE2 )
return a1;
else
return _ftol2(a1);
}
```

does it only hold sse2 support, or generally instruction set availability?
