Alessandro Gatti	7bb5f2da9d	py/asmthumb: Remove redundant load/store opcode implementations. ... This commit removes load/store opcode implementations that have been made redundant in 1f5ba6998b. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2025-07-01 15:34:29 +10:00
Alessandro Gatti	12f36cc13c	py/asmxtensa: Implement the full set of Viper load/store operations. ... This commit expands the implementation of Viper load/store operations that are optimised for the Xtensa platform. Now both load and store emitters should generate the shortest possible sequence in all cases. Redundant specialised operation emitters have been aliased to the general case implementation - this was the case of integer-indexed load/store operations with a fixed offset of zero.

Alessandro Gatti	cd1b921bf2	py/asmarm: Implement the full set of Viper load/store operations. ... This commit expands the implementation of Viper load/store operations that are optimised for the Arm platform. Now both load and store emitters should generate the shortest possible sequence in all cases. Redundant specialised operation emitters have been folded into the general case implementation - this was the case of integer-indexed load/store operations with a fixed offset of zero.

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.

Andrew Leech	2f04381aeb	extmod/modlwip: Fix crash when calling recv on listening socket. ... Add check to prevent calling recv on a socket in the listening state.

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.

Andrew Leech	09541b7896	py/repl: Skip private variables when printing tab completion options. ... Any '_' variables/functions in frozen modules are currently printed, when they shouldn't be. That's due to underscore names possibly existing between the start and end qstrs which are used to print the auto-complete matches. The underscore names should be skipped when iterating between the two boundary qstrs. The underscore attributes are removed from the extra coverage exp file because tab completing "import <tab>" no longer lists modules beginning with an underscore.

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

Damien George	d9467b07cb	tools/mpremote: Improve df command to use new no-arg vfs.mount() query. ... The existing `mpremote df` command is not very good, because it needs to assume that all directories in the root directory are mount points, and also doesn't correctly stat filesystems when the current directory is not the root. This leads to wrong results With the introduction of `vfs.mount()` to return a list of mounted filesystems and their path, a much better df can be implemented, as done in this commit. The new df will also fall back to using the old approach of listing the root directory if the no-arg `vfs.mount()` query is not supported.
