What is MCode?

MCode is short for machine code. Basically, it is compiled code : instructions in binary form for the CPU to execute. The main advantages of MCode is speed and the possibility to execute low-level code, such as Assembly.

Getting started

Currently, there are two MCode functions available for AutoHotkey. Bentschi's version is recommended.

Laszlo's version :
How to use it : http://www.autohotkey.com/board/topic/19483-machine-code-functions-bit-wizardry

MCode(ByRef code, hex) { ; allocate memory and write Machine Code there
	VarSetCapacity(code,StrLen(hex)//2)
	Loop % StrLen(hex)//2
		NumPut("0x" . SubStr(hex,2*A_Index-1,2), code, A_Index-1, "Char")
}

Bentschi's version :
How to use it : http://ahkscript.org/boards/viewtopic.php?f=7&t=32

MCode(mcode) {
	static e := {1:4, 2:1}, c := (A_PtrSize=8) ? "x64" : "x86"
	if (!regexmatch(mcode, "^([0-9]+),(" c ":|.*?," c ":)([^,]+)", m))
		return
	if (!DllCall("crypt32\CryptStringToBinary", "str", m3, "uint", 0, "uint", e[m1], "ptr", 0, "uint*", s, "ptr", 0, "ptr", 0))
		return
	p := DllCall("GlobalAlloc", "uint", 0, "ptr", s, "ptr")
	if (c="x64")
		DllCall("VirtualProtect", "ptr", p, "ptr", s, "uint", 0x40, "uint*", op)
	if (DllCall("crypt32\CryptStringToBinary", "str", m3, "uint", 0, "uint", e[m1], "ptr", p, "uint*", s, "ptr", 0, "ptr", 0))
		return p
	DllCall("GlobalFree", "ptr", p)
}

Setting up GCC

There are many GCC distributions for the Microsoft Windows Operating System.
Here are some recommended ones :
- MinGW : http://www.mingw.org/wiki/Getting_Started
- TDM-GCC : https://jmeubank.github.io/tdm-gcc/
- Cygwin : https://cygwin.com/install.html
