genmc is an IDAPython script/plugin hybrid that displays Hexrays decompiler microcode, which can help in developing microcode plugins.
By running the code as a script within IDA, a Python shell command becomes available which, after typing "install_plugin()", copies the script to $HOME/.idapro/plugins or %APPDATA%Hex-Rays/IDA Pro/plugins.
With the script installed into the plugins folder, it can be invoked from the plugins menu or by using the hotkey 'Ctrl-Shift-M'.
IDA and decompilers >= 7.3 are required.
This IDAPython project is compatible with Python3. For compatibility with older versions of IDA, you may want to check out the Python2 branch of this project.
