Hello,
does someone may test for me the following using the new Delphi 2007
while some BASM functions are not build in Delphi 7
--------------------------------------------------------------------------------------------------------------------
program BASMTest;
{$APPTYPE CONSOLE}
uses
SysUtils;
Procedure Test;
Const
CD_1 : Double = 1.04;
CE_1 : Extended = 1.04;
Asm
Ret
// Delphi 7 OK
//''''''''''''
fst qword ptr [edi]
fmul qword ptr [CD_1]
fld tbyte ptr [edi]
fstp tbyte ptr [edi]
// Delphi 7 BUG !!!
//'''''''''''''''''
fst tbyte ptr [edi]
fmul tbyte ptr [CE_1]
End;
begin
end.
--------------------------------------------------------------------------------------------------------------------
Best regards
hpw |

Both statements do not compile in Delphi 2007

There is no FST with extended type. You must use FSTP.

Same here - load it first, then multiply.

OK,
I see now, while this functions are regarding the Intel Doc's not
implemented and must be used first using fld st(0) then the fstp!
Thanks
