README
A simple assembler in Lape, requires Simba 1.2+ or just the latest lape interpreter (might need tweaks). Operations follow the same order as found in AT&T syntax, opcode names are mainly similar to Intel's.
Basic example:
{$I slackasm/assembler.pas}
var
Assembler: TSlackASM;
Callable: external procedure();
x: Int32 = 2;
y: Int32 = 100;
z: Int32;
begin
// compute: (x + y) * x
with Assembler := TSlackASM.Create() do
try
Code += _mov (mem(x), eax); // eax := x
Code += _add (mem(y), eax); // eax := eax += y
Code += _imul(mem(x), eax); // eax := eax *= x;
Code += _mov (eax, mem(z)); // z := eax;
Code += _ret;
Callable := Finalize(); // "Build" the method
finally
Free();
end;
// execute the code
Callable();
WriteLn([x, y, z]); //prints 2, 100, 204
// free the code
FreeMethod(@callable);
