592affce3f stm32/make-stmconst.py: Fix missing peripheral consts in stm module.
Lines like the following were not handled by `make-stmconst.py`:

    #define APBPERIPH_BASE        (PERIPH_BASE)

This leads to missing definitions on stm module.  For example, `stm.RTC` is
not defined if `RTC_BASE` is defined as

    #define RTC_BASE              (APBPERIPH_BASE + 0x00002800UL)

because `APBPERIPH_BASE` is not handled as a valid id.

This patch modifies the RegExp so it can handle the above.

8c389db6ea unix/main: Ensure atexit function is called with -m <module>.
Previously, when running `micropython -m <module>` and the module called
sys.exit(), the registered atexit function was not executed. This was due
to sys.exit() raising a SystemExit exception, which bypassed the atexit
handler. This change fixes the issue so that the atexit function is
properly invoked when exiting via sys.exit().

Additionally, following the pattern in execute_from_lexer(),
mp_hal_set_interrupt_char() and mp_handle_pending() handling were added to
ensure that the atexit function is also executed when the user exits via
Ctrl-C.

cf097932a2 unix/modsocket: Set file descriptor to -1 on close.
After s.close(), s.fileno() now returns -1, matching CPython behavior.
Some code relies on this compatibility, as it allows checking whether
a socket is closed by testing its fileno() value. This change ensures
better interoperability with existing Python code and libraries.

This commit enables generation of Zba opcodes by the native emitter
for the Pico2, as its RISC-V implementation supports both of those
extensions (see section 3.8 of the RP2350 datasheet).

40dbf77415 py/emitinlinerv32: Add Zba opcodes to the inline assembler.
This commit adds support for Zba opcodes to the RV32 inline assembler.

Three new opcodes were added, SH1ADD, SH2ADD, and SH3ADD, which performs
a scaled addition (by 1, 2, or 3 bits respectively).  At the moment only
qemu's VIRT_RV32 and rp2's RPI_PICO2/RPI_PICO2_W ports support these
opcodes (the latter only when using the RISCV variant).

965c77ade9 mpy-cross/main: Add support for RV32 Zba opcodes.
This commit adds a new command line switch to inform the RV32 emitter to
use Zba opcodes in its output.

A new implementation-specific option was introduced, called
"-march-flags", that will contain a list of additional
architecture-specific flags to pass to the chosen native emitter
implementation.

At the moment only the RV32 emitter can make use of this command line
facility: if the architecture flags string equals to "zba"
(case-sensitive), then the native emitter will emit Zba opcodes if it
has a chance to do so.

At the moment there is no check on whether additional architecture flags
using to build a MPY file are compatible with the target the output code
is run on, so use this with caution.

cb7ca6f1bc py/asmrv32: Use RV32 Zba opcodes if possible.
This commit adds optional support for selected Zba opcodes (address
generation) to speed up Viper and native code generation on MCUs where
those opcodes are supported (namely RP2350).

Right now support for these opcodes is opt-in, as extension detection
granularity on the RISC-V platform is still a bit in flux.  Relying on
the 'B' bit in the MISA register may yield both false positives and
false negatives depending on the RISC-V implementation the check runs
on.

As a side-effect of Zba support, regular non-byte load/stores have been
made shorter by two bytes.  Whilst this makes code using Zba take up the
same space as non-Zba code, the former will still be faster as it will
have to process just one instruction instead of two, without stalling
registers between the shift and the addition needed to compute the final
offset.

42ea7bc32a py/mpstate: Make it possible for mpy-cross to set emitter options.
This commit introduces a way for mpy-cross to pass a set of options to
the chosen emitter.

This is achieved by adding an opaque pointer to the dynamic compiler
state structure that is only accessed by emitters that have a need to
receive options from mpy-cross when generating code.  That's a way to
make this feature possible without breaking any existing code or
emitter, and without re-engineering the compiler entry point function
(together with passing the options struct downstream until it's time to
emit code).

The main use case for this is letting the RV32 emitter know which
optional extensions it can generate code with, to be able to emit better
suited code for the platform in use.

This adds a QEMU-based bare metal RISC-V 64 bits port.  For the time being
only QEMU's "virt" 64 bits board is supported, using the lp64 ABI and the
RV64IMC architecture.

The port's README is also updated to keep track of these changes.

c4d99f34ae stm32/uart: Fix LPUART init failure with low baudrate.
UART prescaler value should set up correctly to initialize LPUART with low
baudrate for STM32G0/G4/H5.  This can be implemented similarly to
STM32H7/N6/WB.

a69425b533 unix/Makefile: Add additional testing targets.
These are convenience targets for running specific tests as a developer.
They are more useful that invoking run-tests directly as they take account
of the VARIANT= specified on the make command-line.

For instance, you can run all tests matching the regular expression "int"
with `make VARIANT=... test//int`.

The new targets are all documented in README.md.

These flags were were originally made part of the public API in

This commit also includes a fix to the `var-6.2-instance-speciallookup.py`
test originally added by 82db5c8 / #16806, as the `__getattr__` method
actually does not trigger a class's special lookups flag as originally
believed.

f0c6f16b9e all: Remove Python 2.7 support.
Python 2.7 has been EOL since January 2020.

Ubuntu oldoldlts (Focal Fossa, 20.04) has Python 3.8.  Debian oldoldstable
(Buster, from 2019) has Python 3.7.  RHEL 8 (from 2019) has Python 3.6.

It's easier than ever to install a modern Python using uv.

Given this, it seems like a fine idea to drop Python 2.7 support.

Even though the build is not tested on Python as old as 3.3, I left
comments stating that "3.3+" is the baseline Python version.  However, it
might make sense to bump this to e.g., 3.10, the oldest Python 3 version
used during CI. Or, using uv or another method actually test on the oldest
Python interpreter that is desirable to support (uv goes back to Python 3.7
easily; in October 2025, the oldest supported Python interpreter version
will be 3.10)

This commit documents and verifies the current absence of
`__init_subclass__` functionality, in anticipation of a possible future
PEP487 'metaclasses lite' patch.

The main `core_class_initsubclass.py` test verifies if the method is
automatically called, while the other three verify other orthogonal
properties it should have: if the method is an implicit classmethod; if
MicroPython supplies the base case for the usual recursive function body
the PEP encourages; and if kwargs inheritance parameters work correctly.

The calls signature for gc_malloc was changed in
5ed578e5b4, without cleaning up existing

to an int with the same meaning.

This commit goes back and cleans up existing invocations to make their
behavior more readable in a modern context.
