Re: Skybuck presents Faster Div 7

Delphi uses a different calling convention then C by default.

So your supplied assembler routine is not working in Delphi:

I also tried specifieing the calling convention as stdcall, and cdecl, but

so far it's not working...

// this code not working correctly because of different calling
conventions 
(?)
// I tried none, cdecl, and stdcall, which both result in access violation

?!?
function AsmDiv7v3( Value : longword ) : longword; cdecl;
asm
   mov ecx, dword[esp+4]
   mov eax, $24924925
   mov dword[esp+4], 0
@[EMAIL PROTECTED]
   cmp ecx, 1431655764
   jbe @[EMAIL PROTECTED]
   sub ecx, 1431655764
   add dword[esp+4], 204522252
   jmp @[EMAIL PROTECTED]
   mul ecx
   mov eax, edx
   add eax, dword[esp+4]
end;

// Or maybe the code is just bugged ? Who knows ;)

:(

So I can't test it, and I can't verify it, and I can't benchmark it :(

Thanks for trying.

Maybe you can fix it for Delphi ? ;)

Bye,
