* all: Rename the "NORETURN" macro to "MP_NORETURN".Alessandro Gatti2025-05-13
| | | | | | | | | | | | | | | | This commit renames the NORETURN macro, indicating to the compiler that a function does not return, into MP_NORETURN to maintain the same naming convention of other similar macros. To maintain compaitiblity with existing code NORETURN is aliased to MP_NORETURN, but it is also deprecated for MicroPython v2. This changeset was created using a similar process to decf8e6a8bb940d5829ca3296790631fcece7b21 ("all: Remove the "STATIC" macro and just use "static" instead."), with no documentation or python scripts to change to reflect the new macro name.

* all: Remove the "STATIC" macro and just use "static" instead.Angus Gratton2024-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The STATIC macro was introduced a very long time ago in commit d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was to have the option to define it to nothing so that all static functions become global functions and therefore visible to certain debug tools, so one could do function size comparison and other things. This STATIC feature is rarely (if ever) used. And with the use of LTO and heavy inline optimisation, analysing the size of individual functions when they are not static is not a good representation of the size of code when fully optimised. So the macro does not have much use and it's simpler to just remove it. Then you know exactly what it's doing. For example, newcomers don't have to learn what the STATIC macro is and why it exists. Reading the code is also less "loud" with a lowercase static. One other minor point in favour of removing it, is that it stops bugs with `STATIC inline`, which should always be `static inline`. Methodology for this commit was: 1) git ls-files | egrep '\.[ch]$' | \ xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/" 2) Do some manual cleanup in the diff by searching for the word STATIC in comments and changing those back. 3) "git-grep STATIC docs/", manually fixed those cases. 4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

* shared/libc/string0: Don't deref args for n==0 case.Jim Mussared2023-11-07
| | | | | | | | | | | | | | | | | | | | C99 says that strncmp has UB for either string being NULL, so the current behavior is technically correct, but it's an easy fix to handle this case correctly. 7.1.4: "unless explicitly stated otherwise in the detailed description... if an argument to a function has ...null pointer.. the behavior is undefined". 7.21.1: "Unless explicitly stated otherwise in the description of a particular function in this subclause, pointer arguments on such a call shall still have valid values, as described in 7.1.4". Also make the same change for the minimal version in bare-arm/lib.c. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>

* py/mpconfig: Provide config option for internal printf printer.Damien George2023-03-10
| | | | | | | The C-level printf is usually used for internal debugging prints, and a port/board may want to redirect this somewhere other than stdout. Signed-off-by: Damien George <damien@micropython.org>
* shared/libc/string0: Don't include string.h, and provide __memcpy_chk.Alexey 'alexxy' Shvetsov2021-11-17
| | | | | | | | | | | | | Some toolchains will have string.h defining various macros which can lead to compile errors for string function implementations. Not including string.h fixes this. An implementation of __memcpy_chk is provided for toolchains that enable _FORTIFY_SOURCE. Fixes issue #6046. Signed-off-by: Alexey 'alexxy' Shvetsov <alexxyum@gmail.com>
* shared: Introduce new top-level dir and move 1st party lib code there.Damien George2021-07-12
This commit moves all first-party code developed for this project from lib/ to shared/, so that lib/ now only contains third-party code. The following directories are moved as-is from lib to shared: lib/libc -> shared/libc lib/memzip -> shared/memzip lib/netutils -> shared/netutils lib/timeutils -> shared/timeutils lib/upytesthelper -> shared/upytesthelper All files in lib/embed/ have been moved to shared/libc/. lib/mp-readline has been moved to shared/readline. lib/utils has been moved to shared/runtime, with the exception of lib/utils/printf.c which has been moved to shared/libc/printf.c.
