* Fix a typo in the Makefile that prevented the debug build to be actually
enabled when BTYPE=debug is used.
* Add a missing header in modmachine.c that is used when a debug build is
created.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port. This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.
Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.
The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.
This commit makes all functions and function wrappers in modubinascii.c
STATIC and conditional on the MICROPY_PY_UBINASCII setting, which will
exclude the file from qstr/ compressed-string searching when ubinascii is
not enabled. The now-unused modubinascii.h header file is also removed.
The cc3200 port is updated accordingly to use this module in its entirety
instead of providing its own top-level definition of ubinascii.
This was originally like this because the cc3200 port has its own ubinascii
module which referenced these methods. The plan appeared to be that the
API might diverge (e.g. hardware crc), but this should be done similar to
I2C/SPI via a port-specific handler, rather than the port having its own
definition of the module. Having a centralised module definition also
enforces consistency of the API among ports.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
