py/nlrthumb: Save and restore VFP registers s16-s21 when CPU has them.
These s16-s21 registers are used by gcc so need to be saved.  Future
versions of gcc (beyond v9.1.0), or other compilers, may eventually need
additional registers saved/restored.

See issue #4844.

py/nlr: Use MP_UNREACHABLE at the end of arch-specific nlr_jump funcs.
Recent versions of gcc perform optimisations which can lead to the
following code from the MP_NLR_JUMP_HEAD macro being omitted:

    top->ret_val = val; \
    MP_NLR_RESTORE_PYSTACK(top); \
    *_top_ptr = top->prev; \

This is noticeable (at least) in the unix coverage on x86-64 built with gcc
9.1.0.  This is because the nlr_jump function is marked as no-return, so
gcc deduces that the above code has no effect.

Adding MP_UNREACHABLE tells the compiler that the asm code may branch
elsewhere, and so it cannot optimise away the code.

py: Introduce MP_UNREACHABLE macro to annotate unreachable code.
And use it to replace the same pattern at the end of nlrthumb.c:nlr_jump.

Jeff Epler 1cdac3f16a MP3File: Fix stereo playback on samd AudioOut
There were several problems with the way this worked -- the read_count
approach was too complicated and I made a mistake "simplifying" it from
WaveFile.  And when the right channel was returned, it was off by 1 byte,
making it into static.

Instead, directly track which is the "other" channel that has data
available, and by using the right data type make the "+ channel"
arithmetic give the right result.

This requires a double cast (int16_t*)(void*) due to an alignment warning;
the alignment is now ensured manually, but the compiler doesn't make the
necessary inference that the low address bit must be clear.

Jeff Epler 8c841af946 MP3File: Avoid crash in get_buffer when deinitted
When a playing mp3 is deinitted, it's possible to reach get_buffer,
but all the internal pointers are NULL.  This would lead to a hard fault.
Avoid it by returning GET_BUFFER_ERROR instead.

Jeff Epler f4a5c17b5e supervisor: external_flash: don't call m_free when it's bad
It's extremely dubious that we have these handles that we think
are to GC'd memory at a time when the gc pool may not be initialized.
Hopefully, they WERE valid GC memory and are undisturbed by the teardown
of the interpreter that can lead to this state.

In this case, don't try to m_free them, the memory will become free when
the GC heap is reinitialized.

Closes: #2338 (together with previous commit)

Jeff Epler a08d9e6d8e audiocore: Add MP3File using Adafruit_MP3 library 2019-12-10 14:03:06 -06:00
Jeff Epler a484a93b29 nRF: disk_read must be 4-byte aligned
.. a requirement that oofatfs needs to be taught to respect.

This problem can be demonstrated with the following snippet, except
that the related file ("test.bin") must also be contiguous on the
filesystem.  You can ensure this by reformatting your device's filesystem
before testing, then copying any single file bigger than 4kB to test.bin.

    f = open("test.bin", "rb")
    f.seek(2048)
    b = bytearray(2048)
    v = memoryview(b)
    f.readinto(v[909:])

Closes: #2332
