FPU instructions support

[Ivan]

Looks like currently Snowman doesn't support FPU instructions:

__asm__("fld dword [eax+0x88]");
__asm__("fsub dword [0x5a21a4]");
__asm__("fstp dword [ecx+0xec]");
__asm__("fld dword [eax+0x8c]");
__asm__("fadd dword [0x5a21a4]");
__asm__("fstp dword [ecx+0xf0]");

Any chance to have this feature in future versions?

Close to zero. Somebody has to sit down and get the semantics of instructions implemented. Not me at this moment.
