Alessandro Gatti	2ab06b61b3	py/emitnative: Let emitters know the compiled entity's name. ... This commit introduces an optional feature to provide to native emitters the fully qualified name of the entity they are compiling. This is achieved by altering the generic ASM API to provide a third argument to the entry function, containing the name of the entity being compiled. Currently only the debug emitter uses this feature, as it is not really useful for other emitters for the time being; in fact the macros in question just strip the name away.

Andrew Leech	3a97175f5f	tools/mpremote: Fix disconnect handling on Windows and Linux. ... Changes in this commit: - Handle SerialException on Windows when device disconnects. - Print clean 'device disconnected' message instead of stack trace. - Fix terminal formatting issues on Linux after disconnect. - Return disconnected state after console cleanup to avoid terminal issues. This ensures proper disconnect messages on both platforms without showing confusing error traces to users.

Alessandro Gatti	1b0cdc0794	py/asmthumb: Clean up integer-indexed load/store emitters. ... This commit cleans up the single entry point integer-indexed load/store emitters that have been built by merging the single operand type load/store functions in 1f5ba6998b. To follow the same convention found in RV32 and Xtensa emitters, the function operand size is not named after the left shift amount to apply to the initial offset to get its true byte offset, but by a generic "operand size". Also, those functions were updated to use the new MP_FIT_UNSIGNED macros to perform bit width checks when figuring out which opcode encoding is the best one to use.

Alessandro Gatti	6fd7422a8e	tests/run-tests.py: Allow injected code customisation. ... This commit introduces a mechanism to customise the code that is injected to the board when performing a test file upload and execution. A new argument, --begin", is added so regular Python code can be inserted in the injected fragment between the module file creation and the effective file import. This is needed for running larger tests (usually ones that have been pre-compiled with "--via-mpy --emit native") on ESP8266, as that board does not have enough memory to fit certain blocks of code unless additional configuration is performed.

Alessandro Gatti	0d435959e0	tests/micropython: Improve viper ptr boundary tests. ... This commit reworks the Viper pointer boundary tests in order to make them more accurate and easier to extend. The tests are now easier to reason about in their output, using easier to read values, and bit thresholds are now more configurable. If a new conditional code sequence is introduced, adding a new bit threshold is just a matter of adding a value into a tuple at the beginning of the relevant test file. Load tests have also been made more accurate, with better function templates to test register-indexed operations. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2025-07-01 15:43:02 +10:00

Alessandro Gatti	a8e0369826	py/asmrv32: Implement the full set of Viper load/store operations. ... This commit expands the implementation of Viper load/store operations that are optimised for the RV32 platform. Given the way opcodes are encoded, all value sizes are implemented with only two functions - one for loads and one for stores. This should reduce duplication with existing operations and should, in theory, save space as some code is removed. Both load and store emitters will generate the shortest possible sequence (as long as the stack pointer is not involved), using compressed opcodes when possible.

Alessandro Gatti	703d5acbad	py/misc: Introduce macros to check values' bits size. ... This commit adds two macros that lets check whether a given value can fit an arbitrary number of bits, either as a signed or as an unsigned number. The native emitter code backends perform a lot of bit size checks to see if a particular code sequence can be emitted instead of a generic one, and each platform backend has its own ad-hoc macros (usually one per bit count and signedness). With these macros there's a single way to perform those checks, plus there's no more chance for off-by-one mask length errors when dealing with signed numbers.

Yoctopuce dev	e57aa7e70a	py/obj: Fix nan handling in object REPR_C and REPR_D. ... CPython math.nan is positive with regards to copysign. The signaling bit (aka sign flag) was incorrectly set. In addition, REPR_C and REPR_D should only use the _true_ nan to prevent system crash in case of hand-crafted floats. For instance, with REPR_C, any nan-like float following the pattern `01111111 1xxxxxxx xxxxxxxx xxxxx1xx` would be switched to an immediate object or a qstr string. When the qstr index is too large, this would cause a crash. This commit fixes the issue, and adds the relevant test cases. Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>	2025-06-24 00:30:08 +10:00
Yoctopuce dev	66c0148022	py/runtime: Add support for using __all__ in star import. ... When the symbol `__all__` is defined in a module, `mp_import_all()` should import all listed symbols into the global environment, rather than relying on the underscore-is-private default. This is the standard in CPython. Each item is loaded in the same way as if it would be an explicit import statement, and will invoke the module's `__getattr__` function if needed. This provides a straightforward solution for fixing star import of modules using a dynamic loader, such as `extmod/asyncio` (see issue #7266). This improvement has been enabled at BASIC_FEATURES level, to avoid impacting devices with limited ressources, for which star import is of little use anyway. Additionally, detailled reporting of errors during `__all__` import has been implemented to match CPython, but this is only enabled when ERROR_REPORTING is set to MICROPY_ERROR_REPORTING_DETAILED.

Phil Howard	b725c26b4e	rp2/rp2_flash: Add MICROPY_HW_FLASH_MAX_FREQ to replace fixed max freq. ... Assuming a 133MHz capable flash in 91cff8e4f1 caused `rp2_flash_set_timing_internal` to set out of range dividers for some boards (anything with value of 4 and flash that doesn't tolerate higher speeds). This affected (at least) the XIAO RP2350 board, making it non-bootable. Since Pico SDK's `PICO_FLASH_SPI_CLKDIV` is entirely unreliable on a system with a variable system clock (users can change it at runtime) then use it only to work out a default `MICROPY_HW_FLASH_MAX_FREQ`. This value can be overridden in board config. Note that RP2350's default clock is 150MHz, RP2040's is 125MHz and it has been certified at 200MHz so it's quite possible that `PICO_FLASH_SPI_CLKDIV` is unreliable even at standard RP2 clocks. (If flash timings are marginal then this can manifest as instability rather than outright failure.) Fixes issue #17375. Signed-off-by: Phil Howard <github@gadgetoid.com>	2025-06-17 11:40:42 +10:00
