=={{header|D}}==

In D you usually use a nicer <code>asm {}</code> statement for similar purposes.

<lang d>int test(in int a, in int b) pure nothrow @nogc {

/*

mov EAX, [ESP+4]

add EAX, [ESP+8]

ret

*/

immutable ubyte[9] code = [0x8B, 0x44, 0x24, 0x4, 0x3, 0x44, 0x24, 0x8, 0xC3];

alias F = extern(C) int function(int, int) pure nothrow @nogc;

immutable f = cast(F)code.ptr;

return f(a, b); // Run code.

}

void main() {

import std.stdio;

test(7, 12).writeln;

}</lang>

{{out}}
