The STATIC macro was introduced a very long time ago in commit d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was to have the option to define it to nothing so that all static functions become global functions and therefore visible to certain debug tools, so one could do function size comparison and other things. This STATIC feature is rarely (if ever) used. And with the use of LTO and heavy inline optimisation, analysing the size of individual functions when they are not static is not a good representation of the size of code when fully optimised. So the macro does not have much use and it's simpler to just remove it. Then you know exactly what it's doing. For example, newcomers don't have to learn what the STATIC macro is and why it exists. Reading the code is also less "loud" with a lowercase static. One other minor point in favour of removing it, is that it stops bugs with `STATIC inline`, which should always be `static inline`. Methodology for this commit was: 1) git ls-files | egrep '\.[ch]$' | \ xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/" 2) Do some manual cleanup in the diff by searching for the word STATIC in comments and changing those back. 3) "git-grep STATIC docs/", manually fixed those cases. 4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

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.
If the Python code contains @native
or @viper
annotations, then you must
specify -march
to match the target architecture.
Run ./mpy-cross -h
to get a full list of options.
The optimisation level is 0 by default. Optimisation levels are detailed in https://docs.micropython.org/en/latest/library/micropython.html#micropython.opt_level
