Even the modules whose names don't start with "u" prefix are micro-ified
anyway, i.e. provide only subset of CPython's functionality (and sometimes
extensions to it). So, it doesn't make much sense to devide them by
criteria of having/not having "u" prefix.
The C standard says that left-shifting a signed value (on the LHS of the
operator) is undefined. So we cast to an unsigned integer before the
shift. gcc does not issue a warning about this, but clang does.
All Flash sans firmware at the beginning and 16K SDK param block at the
end is used for filesystem (and that's calculated depending on the Flash
size).
Builds have been broken since reworking autogeneration in c618f91 and
related, this gets fixed here by applying similar qstr generation logic
for the msvc builds: c files are only preprocessed when changed (or not
yet preprocessed) and the concatenated output is fed into makeqstrdefs.py.
To speed up this process, the concatenated output is already filtered to
contain only lines which makeqstrdefs really needs: this makes the qstr
generation stage about twice as fast (checked on different machines).
- msvc preprocessor output contains full paths with backslashes so the
':' and '\' characters needs to be erased from the paths as well
- use a regex for extraction of filenames from preprocessor output so it
can handle both gcc and msvc preprocessor output, and spaces in paths
(also thanks to a PR from @travnicekivo for part of that regex)
- os.rename will fail on windows if the destination file already exists,
so simply attempt to delete that file first
