mp_compile no longer takes an emit_opt argument, rather this setting is now provided by the global default_emit_opt variable. Now, when -X emit=native is passed as a command-line option, the emitter will be set for all compiled modules (included imports), not just the top-level script. In the future there could be a way to also set this variable from a script. Fixes issue #4267. |

MicroPython cross compiler
This directory contains the MicroPython cross compiler, which runs under any Unix-like system and compiles .py scripts into .mpy files.
Build it as usual:
$ make
The compiler is called mpy-cross. Invoke it as:
$ ./mpy-cross foo.py
This will create a file foo.mpy which can then be copied to a place accessible
by the target MicroPython runtime (eg onto a pyboard's filesystem), and then
imported like any other Python module using import foo.
Different target runtimes may require a different format of the compiled bytecode, and such options can be passed to the cross compiler. For example, the unix port of MicroPython requires the following:
$ ./mpy-cross -mcache-lookup-bc foo.py
Run ./mpy-cross -h to get a full list of options.
