AW: RotateLeft: 32-Bit Integer rotieren
17. Aug 2011, 10:34
Hallo,
So gehts:
Delphi-Quellcode:
asm
mov cl, bits
mov eax, zahl
rol eax, cl
mov zahl, eax
end;
Oder so:
Delphi-Quellcode:
function rol(Zahl: Integer; Bits: Byte): Integer;
asm
xchg cl, dl
rol eax, cl
end;
Delphi-Quellcode:
var zahl: UInt32;
bits: UInt8;
begin
Zahl := $80000000;
bits := 1;
Caption := IntToStr(rol(Zahl,bits));
end;

but because their imagination reveals worlds that others cannot see."
