Reduces size of this port by about 3300 bytes, and demonstrates how to use
this feature.

This commit simplifies and cleans up the bare-arm port, and adds just
enough system and library code to make it execute on an STM32F405 MCU.
The mpconfigport.h configuration is simplified to just specify those
configuration values that are different from the defaults. And the
addition of -fdata-sections and -ffunction-sections means the final
firmware is smaller than it previously was, by about 4200 bytes.
A README is also added.

To keep these ports as minimal as possible.

Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32,
esp8266, cc3200, teensy, qemu-arm, nrf. Not enabled on others to be able
to test the code when the feature is disabled (the default case).

To enable lazy loading of submodules (among other things), which is very
useful for MicroPython libraries that want to have optional subcomponents.
Disabled explicitly on minimal ports.

|
This is run with uncrustify 0.70.1, and black 19.10b0.
|
|
This string is recognised by uncrustify, to disable formatting in the
region marked by these comments. This is necessary in the qstrdef*.h files
to prevent modification of the strings within the Q(...). In other places
it is used to prevent excessive reformatting that would make the code less
readable.

Many ports already allow overriding CROSS_COMPILE. This modifies the
remaining ports to allow it as well.
|
|
This option affects py/vm.c and py/gc.c and using -Os gets them compiling a
bit smaller, and small firmware is the aim of these two ports. Also,
having these files compiled with -Os on these ports, and -O3 as the default
on other ports, gives a better understanding of code-size changes when
making changes to these files.
|
|
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.

On by default, turned off for minimal/bare-arm. Saves 144 bytes on x86.
|
|
Configurable via MICROPY_PY_BUILTINS_STR_COUNT. Default is enabled.
Disabled for bare-arm, minimal, unix-minimal and zephyr ports. Disabling
it saves 408 bytes on x86.
|
|
Default is enabled, disabled for minimal builds. Saves 1296 bytes on x86,
976 bytes on ARM.
|
|
These ports don't need anything from extmod so don't include those files
at all in the build. This speeds up the build by about 10% when building
with a single core.

Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.
|
|
Also renames "stmhal" to "stm32" in documentation and everywhere else.
|
|
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.
