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 change is made for two reasons:
1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system
provided errno for certain errors, and yet MicroPython stream objects
that it calls will be using the internal mp_stream_errno. So if the
library returns an error it is not known whether the corresponding errno
code is stored in the system errno or mp_stream_errno. Using the system
errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this
ambiguity.
2. For systems that have threading the system-provided errno should always
be used because the errno value is thread-local.
For systems that do not have an errno, the new lib/embed/__errno.c file is
provided.

'force' in order not to alter the comments which use extra spaces after //

This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.
This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.
Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):
git submodule deinit lib/tinyusb
rm -rf .git/modules/lib/tinyusb
git submodule update --init lib/tinyusb

This is run with uncrustify 0.70.1, and black 19.10b0.
|
|
This is a more logical place to clear the KeyboardInterrupt traceback,
right before it is set as a pending exception. The clearing is also
optimised from a function call to a simple store of NULL.
|
|
This function is tightly coupled to the state and behaviour of the
scheduler, and is a core part of the runtime: to schedule a pending
exception. So move it there.
|
|
Pending exceptions would otherwise be handled later on where there may not
be an NLR handler in place.
A similar fix is also made to the unix port's REPL handler.
Fixes issues #4921 and #5488.

By simply reordering the enums for pyexec_mode_kind_t it eliminates a data
variable which costs ROM to initialise it. And the minimal build now has
nothing in the data section.
It seems the compiler is smart enough so that the generated code for
if-logic which tests these enum values is unchanged.

This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively. It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.
Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.
The features are enabled on unix micropython-coverage and micropython-dev.

During readline development, this function may receive bad `pos` values.
It's easier to understand the assert() failing error than to have a "stack
smashing detected" message.
|
|
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.
For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.
|
|
This helps to prevent mistakes, and allows easily changing the ROM value of
None if needed.

This reverts commit f4ed2dfa942339dc1f174e8a83ff0d41073f1972.
This lets tinytest work as it was originally designed. An alternate
solution for the reverted commit will be implemented in a future commit.

They are needed for littlefs.

Identical to cd527bb324ade952d11a134859d38bf5272c165e but for doubles.
This gives a -2.754% improvement on bm_float.py, and -35% improvement on
calling sqrt in a loop.

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.

And this library now includes the startup_stm32*.s files for each MCU.

A port must provide the following function for this to work:
uintptr_t mp_hal_stdio_poll(uintptr_t poll_flags);

Updating the nrfx git submodule containing HAL drivers for nrf-port
from v1.3.1 to current master. The version pointed to is one commit
ahead of v1.7.1 release. The extra commit contains a bugfix for
nrfx_uart_tx_in_progress() making it report correctly.
The general upgrade of nrfx is considered to be safe, as almost all
changes in between 1.3.1 and 1.7.1 are related to peripherals and
target devices not used by the nrf-port as of today.

Otherwise mp_interrupt_char will have a value of zero on start up (because
it's in the BSS) and a KeyboardInterrupt may be raised during start up.
For example this can occur if there is a UART attached to the REPL which
sends spurious null bytes when the device turns on.
|
|
So that boot.py and/or main.py can be frozen (either as STR or MPY) in the
same way that other scripts are frozen. Frozen scripts have preference to
scripts in the VFS.
|
|
It will only execute the script if it can be stat'd and is a file.

commit cb05c9486d3b48ffd6bd7542d8dbbab4b1caf790.
Large code pages (932, 936, 949, 950) have been removed from ffunicode.c
because they were not included in previous versions here.
