Damien George 24c3e9b283 py/modstruct: Fix struct.pack_into with unaligned offset of native type.
Following the same fix for unpack.

Tom McDermott 1022f9cc35 py/modstruct: Fix struct.unpack with unaligned offset of native type.
With this patch alignment is done relative to the start of the buffer that
is being unpacked, not the raw pointer value, as per CPython.

Fixes issue #3314.

Jeff Epler 12f13ee634 py/objtuple: Allow compatible subclasses of tuple in mp_obj_tuple_get.
As part of this patch a private macro mp_obj_is_tuple_compatible is
introduced to encapsulate the check, which is used in two locations.

Fixes #5005.

Milan Rossa 310b3d1b81 py: Integrate sys.settrace feature into the VM and runtime.
This commit adds support for sys.settrace, allowing to install Python
handlers to trace execution of Python code.  The interface follows CPython
as closely as possible.  The feature is disabled by default and can be
enabled via MICROPY_PY_SYS_SETTRACE.

Damien George c7c6703950 py/compile: Improve the line numbering precision for lambdas.
Prior to this patch the line number for a lambda would be "line 1" if the
body of the lambda contained only a simple expression (with no line number
stored in the parse node).  Now the line number is always reported
correctly.

Damien George af20c2ead3 py: Add global default_emit_opt variable to make emit kind persistent.
mp_compile no longer takes an emit_opt argument, rather this setting is now
provided by the global default_emit_opt variable.

Now, when -X emit=native is passed as a command-line option, the emitter
will be set for all compiled modules (included imports), not just the
top-level script.

In the future there could be a way to also set this variable from a script.

Fixes issue #4267.

Damien George 08c1fe5569 py/vm: Don't add traceback info for exceptions that are re-raised.
With this patch exceptions that are re-raised have improved tracebacks
(less confusing, match CPython), and it makes re-raise slightly more
efficient (in time and RAM) because they no longer need to add a traceback.
Also general VM performance is not measurably affected.

Partially fixes issue #2928.

Damien George 16f6169c88 py/vm: Don't add traceback info for exc's propagated through a finally.
With this patch exception tracebacks that go through a finally are improved

efficient (in time and RAM) because they no longer need to add a traceback.

Partially fixes issue #2928.

Damien George 519746cae4 extmod/crypto-algorithms: Add source to header and populate copyright.
As per the README.md of the upstream source at
https://github.com/B-Con/crypto-algorithms, this source code was released
into the public domain, so make that explicit in the copyright line in the
header.

Damien George 2fca0d7f18 py/vm: Shorten error message for not-implemented opcode.
It's really an opcode that's not implemented, so use "opcode" instead of
"byte code".  And remove the redundant "not implemented" text because that
is already implied by the exception type.  There's no need to have a long
error message for an exception that is almost never encountered.  Saves
about 20 bytes of code size on most ports.

Jim Mussared 0bd1eb80ff qemu-arm: Add testing of frozen native modules.
- Split 'qemu-arm' from 'unix' for generating tests.
- Add frozen module to the qemu-arm test build.
- Add test that reproduces the requirement to half-word align native
  function data.

Jim Mussared 4ab5156c01 tools/mpy-tool.py: Force native func alignment to halfword/word on ARM.
This is necessary for ARMV6 and V7.  Without this change, calling a frozen
native/viper function that is misaligned will crash.

Damien George 7d851a27f1 extmod/modure: Make regex dump-code debugging feature optional.
Enabled via MICROPY_PY_URE_DEBUG, disabled by default (but enabled on unix
coverage build).  This is a rarely used feature that costs a lot of code
(500-800 bytes flash).  Debugging of regular expressions can be done
offline with other tools.

Damien George 11ecdf2ec6 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.
2019-08-19 16:14:57 +10:00
Damien George 0c80cb39af 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.

MICROPY_PY_MATH_ISCLOSE which is disabled by default, but enabled for the
ports which already have MICROPY_PY_MATH_SPECIAL_FUNCTIONS enabled.

Damien George 3eff81288c stm32/i2c: Fix generation of restart condition for hw I2C on F0/F7.
Before this patch I2C transactions using a hardware I2C peripheral on F0/F7
MCUs would not correctly generate the I2C restart condition, and instead
would generate a stop followed by a start.  This is because the CR2 AUTOEND
bit was being set before CR2 START when the peripheral already had the I2C
bus from a previous transaction that did not generate a stop.

As a consequence all combined transactions, eg read-then-write for an I2C
memory transfer, generated a stop condition after the first transaction and
didn't generate a stop at the very end (but still released the bus).  Some
I2C devices require a repeated start to function correctly.

This patch fixes this by making sure the CR2 AUTOEND bit is set after the
start condition and slave address have been fully transferred out.
