Now only persists __persistent_data, and adds low_power_persistent_pstate_get function to return the pstate that persists all that data
This uses a new pico_ld_constants.ld file, to allow CMake to modify the addresses of persistent data and the heap
This new __persistent_data is only supported with HAS_POWMAN_TIMER, and does not work if your binary is signed
* Enable hard-float ABI support for pico_float and pico_double on m33
Resolves#2783
Signed-off-by: Andy Lin <andylinpersonal@gmail.com>
* Add (non google) LLVM support, and replace calling convention check with #if defined(__ARM_PCS_VFP)
* switch float.h to use static inline method for int2float() etc in VFP mode rather than #define
* float/double test cleanup - particularly:
- splitting out executable for each test type for pico_float/double_test
- removing undefined behavior from custom_float_funcs_test.c, to de-confuse clang
- add test of denormal->int
Note some tests still fail on llvm libc (at least version 19)
* fix some issues with newer llvm_libc/compiler as used by bazel build
* keep check_configs happy
* another bazel issue
* introduce pico_double_pico_dcp for consistency
* fixup debug output based on previous commit
* remove unnecessary build guard from double_conv_m33.S
* allow -1 for neg_denormal->int rounding towards minus infinity
* Update test/pico_float_test/CMakeLists.txt

* - add fma/_fast functions to pico_float_test/pico_double_test
- fix guard for TEST_SATURATION in pico_double_test - GCC doesn't clamp either
* - double functions were only wrapped in pico_double_pico not pico_double_pico_dcp explicitly (i.e. explicitly setting double impl to pico_dcp was not selecting our versions)
* avoid extra stack alignment push (per review comment)
* fix fma return code in VFP mode (register transfer was the wrong way around)
* separate PCS=VFP and non-PCS-VFP versions of fma_fast
* remove saving_func_return (which is just bx lr) and fold the separate pop of lr, into a pop of pc
* better fix for wrapping right libraries
* rename some labels from _entry (which is an internal entry point) to _softfp to be clear that these are the function entry points which work with softfp calling conventions
* Make bazel pico_float build not wrap SCI functions on RISC-V to match CMake build
* Split out FMAF as a selectable wrapped item since we don't want to wrap it for VFP
* fix typos
* fix test

This is an automated change with the following commands:
$ find . -name "BUILD.bazel" -o -name "*.bzl" \
-exec buildifier -lint=fix {} \;
* Add missing `load()` statements for things provided by @rules_cc. This
is required for Bazel >9.
* Sort attributes on build targets.
* Add missing trailing commas where applicable.
* miscellaneous cleanup:
* cleanup some #ifdefs which were slightly hacky when RP2350 was added; use HAS_ flags in preference to PICO_RP2040/RP2350
* make some dependencies more explicit - i.e. compile if the user doesn't want to include certain libraries
* cleanup some directory A -> directory B relative path names in CMakeLists.txt to be SDK root -> directory B
* add pioasm --version, and print version number in generated files
* Hook up pio version string in Bazel build

If you set the timezone, aon_timer_get_time can wrongly apply a
daylight saving time adjustment based on the stack contents. This can
make it appear that time has gone backwards.
Make sure datetime_to_tm initialises tm_isdst to -1.
Fixes#2374
* Update LwIP to 2.2.1
* Update to mbedtls to 3.6.1
* Update lib/cyw43-driver to 1.1.0
* Support using a more recent version of mbedtls
altcp_tls_mbedtls.c is not compatible with mbedtls 3.x so use a
patched version until this is resolved.
* Make sure MBEDTLS_VERSION_MAJOR is visible to LwIP.
* Test mbedtls in kitchen sink
* Add mbedtls to bazel
If you call rtc_get_datetime immediately after rtc_set_datetime you get
junk back. According to the datasheet "Writing to the RTC will take
2 clk_rtc clock periods to arrive". So add a delay after calling
rtc_set_datetime in aon_timer_set_time_calendar.
Fixes#2148
* on RP2350 _dcp variant now enables -msoft-float, since if you're using this at all it is likely because you don't want to use the VFP unit at all (to save stack space)
* implement all float_ and double_ conversion functions in all pico_float_pico_ variants and pico_double_pico on RP2040 and RP2350 (many were missing in some combinations)
* provide better granularity of what functions are wrapped in each case
also marked custom_xxx_funcs_test.c as not in bazel build yet
* ta_set_timeout can fail to set an alarm
If alarm_pool_irq_handler takes <1us between handling an alarm and
calling ta_set_timeout then no alarms will be set as it will appear as
if an earlier alarm is already armedi before the target time.
Make sure ta_set_timeout always leaves with an alarm set by checking the
armed status.
Fixes#2118
* ta_disable_irq_handler should unarm its timer
* Initial Pico 2 W Bazel support
Improves compatibility with Pico W and Pico 2 W by fixing issues that
prevented correct linking of wireless libraries.
* Improve correctness and configurability
* Require newer rules_python
* Require rules_python@0.36.0
* Fix missing compatibility expressions
* Minor tweaks
* Minor cleanup
* Update suggested version in Bazel README
* More README tweaks
* Improve Bazel btstack build correctness
* Add XIP cache maintenance API (fixes#2005)
Also add a cache clean to hardware_flash implementations, to avoid
losing pending writes on the subsequent invalidate.
* Fix comment typos, add to docs index, remove unnecessary defaulting of XIP_CACHE assertions on FLASH
* Fix sense of unsigned wrapping test
* update bazel build
