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
* Fix some errors from -fanalyzer.
Includes a genuine bug in multicore_doorbell_claim() which seemed to use the wrong bit for the second core.
* Return NULL instead of panicking on secondary allocation fail in pico_time
Note: the correct solution would be to flush stdout in the short-circuited functions, but this rather destroys the point of making them fast.
This takes care of the common case. For complete/best support use PICO_STDIO_SHORT_CIRCUIT_CLIB_FUNCS=0 when using compiler printf
* Enable hard-float ABI support for pico_float and pico_double on m33
Resolves#2783

* 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.
``__check_nan<f|d><1|2>`` is hard-coded into ``.text`` instead
of being wrapped with ``<double|float>_section`` like other
``__aeabi*`` functions. When those functions are moved to SRAM,
this leaves ``__check_nan*`` in flash, causing GCC to emit a veneer
call that clobbers ip and corrupts the saved ``lr`` in
``wrapper_func_<d|f><1|2>``.
Fixes#2771
