Damien George ea3c80a514 tools/mpy-tool.py: Add support for freezing native code.
This adds support to freeze .mpy files that contain native code blocks.

Damien George 636ed0ff8d py/emitglue: Remove union in mp_raw_code_t to combine bytecode & native. 2019-03-08 15:53:04 +11:00
Damien George 4f0931b21f py/persistentcode: Define static qstr set to reduce size of mpy files.
When encoded in the mpy file, if qstr <= QSTR_LAST_STATIC then store two
bytes: 0, static_qstr_id.  Otherwise encode the qstr as usual (either with
string data or a reference into the qstr window).

Reduces mpy file size by about 5%.
2019-03-05 16:32:05 +11:00
Damien George 992a6e1dea py/persistentcode: Pack qstrs directly in bytecode to reduce mpy size.
Instead of emitting two bytes in the bytecode for where the linked qstr
should be written to, it is now replaced by the actual qstr data, or a
reference into the qstr window.

Reduces mpy file size by about 10%.

Damien George 5996eeb48f py/persistentcode: Add a qstr window to save mpy files more efficiently.
This is an implementation of a sliding qstr window used to reduce the
number of qstrs stored in a .mpy file.  The window size is configured to 32
entries which takes a fixed 64 bytes (16-bits each) on the C stack when
loading/saving a .mpy file.  It allows to remember the most recent 32 qstrs
so they don't need to be stored again in the .mpy file.  The qstr window
uses a simple least-recently-used mechanism to discard the least recently
used qstr when the window overflows (similar to dictionary compression).
This scheme only needs a single pass to save/load the .mpy file.

Reduces mpy file size by about 25% with a window size of 32.

Damien George 5a2599d962 py: Replace POP_BLOCK and POP_EXCEPT opcodes with POP_EXCEPT_JUMP.
POP_BLOCK and POP_EXCEPT are now the same, and are always followed by a
JUMP.  So this optimisation reduces code size, and RAM usage of bytecode by
two bytes for each try-except handler.

Dave Hylands c932639063 tools/pydfu.py: Fix regression so tool runs under Python 2 again.
Under python3 (tested with 3.6.7) bytes with a list of integers as an
argument returns a different result than under python 2.7 (tested with
2.7.15rc1) which causes pydfu.py to fail when run under 2.7.  Changing
bytes to bytearray makes pydfu work properly under both Python 2.7 and
Python 3.6.

Dave Hylands 39eef27083 tools/mpy-tool.py: Fix build error when no qstrs present in frozen mpy.
If you happen to only have a really simple frozen file that doesn't contain
any new qstrs then the generated frozen_mpy.c file contains an empty
enumeration which causes a C compile time error.

Damien George 814d580a15 tools/mpy-tool.py: Fix calc of opcode size for opcodes with map caching.
Following an equivalent fix to py/bc.c.  The reason the incorrect values
for the opcode constants were not previously causing a bug is because they
were never being used: these opcodes always have qstr arguments so the part
of the code that was comparing them would never be reached.

Thanks to @malinah for finding the problem and providing the initial patch.

Damien George 4f25a8b6a4 tools/pydfu.py: Improve DFU reset, and auto-detect USB transfer size.
A DFU device must be in the idle state before it can be programmed, and
this requires either clearing the status or aborting, depending on its
current state.  Code is added to do this.  And the USB transfer size is now
automatically detected so devices with a size less than 2048 bytes work
correctly.

Martin Dybdal 7795b2e5c3 tools/pyboard.py: In TelnetToSerial.close replace try/except with if.
Some Python linters don't like unconditional except clauses because they
catch SystemExit and KeyboardInterrupt, which usually is not the intended
behaviour.

Andrew Leech a2703649ea tools/pydfu: Workaround stdio flush error on Windows with Python 3.6.
There appears to be an issue on Windows with CPython >= 3.6,
sys.stdout.flush() raises an exception:

    OSError: [WinError 87] The parameter is incorrect

It works fine to just catch and ignore the error on the flush line.  Tested
on Windows 10 x64 1803 (Build 17134.228), Python 3.6.4 amd64.

Ayke van Laethem 0d7a088039 tools/pyboard: Run exec: command as a string.
The Python documentation recommends to pass the command as a string when
using Popen(..., shell=True).  This is because "sh -c <string>" is used to
execute the command and additional arguments after the command string are
passed to the shell itself (not the executing command).

Rich Barlow 6e5a40cf3c tools/mpy-tool: Set sane initial dynamic qstr pool size with frozen mods
The first dynamic qstr pool is double the size of the 'alloc' field of
the last const qstr pool. The built in const qstr pool
(mp_qstr_const_pool) has a hardcoded alloc size of 10, meaning that the
first dynamic pool is allocated space for 20 entries. The alloc size
must be less than or equal to the actual number of qstrs in the pool
(the 'len' field) to ensure that the first dynamically created qstr
triggers the creation of a new pool.

When modules are frozen a second const pool is created (generally
mp_qstr_frozen_const_pool) and linked to the built in pool. However,
this second const pool had its 'alloc' field set to the number of qstrs
in the pool. When freezing a large quantity of modules this can result
in thousands of qstrs being in the pool. This means that the first
dynamically created qstr results in a massive allocation. This commit
sets the alloc size of the frozen qstr pool to 10 or less (if the number
of qstrs in the pool is less than 10). The result of this is that the
allocation behaviour when a dynamic qstr is created is identical with an
without frozen code.

Note that there is the potential for a slight memory inefficiency if the
frozen modules have less than 10 qstrs, as the first few dynamic
allocations will have quite a large overhead, but the geometric growth
soon deals with this.

Damien George 8fb95d6520 tools/pydfu.py: Increase download packet size to full 2048 bytes.
The ST DFU bootloader supports a transfer size up to 2048 bytes, so send
that much data on each download (to device) packet.  This almost halves
total download time.

Paul Sokolovsky 43141ddb55 tools/tinytest-codegen: Take --target= option for test set selection.
Gets passed to run-tests --list-tests to get actual list of tests to use.
If --target= is not given, legacy set hardcoded in tinytest-codegen itself
is used.

Also, get rid of tinytest test groups - they aren't really used for
anything, and only complicate processing. Besides, one of the next
step is to limit number of tests per a generated file to control
the binary size, which also will require "flat" list of tests.

Paul Sokolovsky 48e931e1d3 tools/tinytest-codegen.py: Generate code for upytesthelper.
The way tinytest was used in qemu-arm test target is that it didn't test
much. MicroPython tests are based on matching the test output against
reference output, but qemu-arm's implementation didn't do that, it
effectively tested just that there was no exception during test
execution. "upytesthelper" wrapper was introduce to fix it, and so
test generator is now switched to generate test code for it.

Also, fix PEP8 and other codestyle issues.

Damien George dd11af209d py: Add LOAD_SUPER_METHOD bytecode to allow heap-free super meth calls.
This patch allows the following code to run without allocating on the heap:

    super().foo(...)

Before this patch such a call would allocate a super object on the heap and
then load the foo method and call it right away.  The super object is only
needed to perform the lookup of the method and not needed after that.  This
patch makes an optimisation to allocate the super object on the C stack and
discard it right after use.

Changes in code size due to this patch are:

   bare-arm: +128
    minimal: +232
   unix x64: +416
unix nanbox: +364
     stmhal: +184

2017-04-05 00:46:12 +03:00
Paul Sokolovsky 647e72ca63 tools/pyboard: Add "exec" and "execpty" pseudo-devices support.
This allows to execute a command and communicate with its stdin/stdout
via pipes ("exec") or with command-created pseudo-terminal ("execpty"),
to emulate serial access. Immediate usecase is controlling a QEMU process
which emulates board's serial via normal console, but it could be used
e.g. with helper binaries to access real board over other hadware
protocols, etc.

An example of device specification for these cases is:

	--device exec:../zephyr/qemu.sh
	--device execpty:../zephyr/qemu2.sh

Where qemu.sh contains long-long qemu startup line, or calls another
command. There's a special support in this patch for running the command
in a new terminal session, to support shell wrappers like that (without
new terminal session, only wrapper script would be terminated, but its
child processes would continue to run).

Rami Ali b7fa63c7ce tools: Add gen-cpydiff.py to generate docs differences.
This patch introduces the a small framework to track differences between
uPy and CPython.  The framework consists of:

- A set of "tests" which test for an individual feature that differs between
  uPy and CPy.  Each test is like a normal uPy test in the test suite, but
  has a special comment at the start with some meta-data: a category (eg
  syntax, core language), a human-readable description of the difference, a
  cause, and a workaround.  Following the meta-data there is a short code
  snippet which demonstrates the difference.  See tests/cpydiff directory
  for the initial set of tests.

- A program (this patch) which runs all the tests (on uPy and CPy) and
  generates nicely-formated .rst documenting the differences.

- Integration into the docs build so that everything is automatic, and the
  differences appear in a way that is easy for users to read/reference (see
  latter commits).

The idea with using this new framework is:

- When a new difference is found it's easy to write a short test for it,
  along with a description, and add it to the existing ones.  It's also easy
  for contributors to submit tests for differences they find.

- When something is no longer different the tool will give an error and
  difference can be removed (or promoted to a proper feature test).

Damien George f1db8a3097 qemu-arm: Don't compile tests in "REPL" mode.
Previous to this patch the qemu-arm tests were compiled with is_relp=true
meaning that the __repl_print__ function was called for all lines of code
in the outer scope.  This is not the right behaviour for scripts that are
executed as though they were a file (eg tests).

With this fix the micropython/heapalloc_str.py test now works so it is
removed from the test blacklist.

Damien George 98458a46ec tools/mpy-tool.py: Add support for OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.
With caching of map lookups in the bytecode, frozen bytecode can still
work but must be stored in RAM, not ROM.  This patch allows mpy-tool.py to
generate code that works with this optimisation, but it's not recommended
to use it on embedded targets (because of lack of RAM).
2017-01-05 15:52:52 +11:00
Damien George 29b5879613 tools/pyboard.py: Refactor so target is not reset between scripts/cmd.
Previous to this patch pyboard.py would open a new serial connection to
the target for each script that was run, and for any command that was run.
Apart from being inefficient, this meant that the board was soft-reset
between scripts/commands, which precludes scripts from accessing variables
set in a previous one.

This patch changes the behaviour of pyboard.py so that the connection to
the target is created only once, and it's not reset between scripts or any
command that is sent with the -c option.

Damien George ca973bd308 qemu-arm: Enable software floating point support, and float tests.
This helps to test floating point code on Cortex-M hardware.

As part of this patch the link-time-optimisation was disabled because it

could not find the __aeabi_f2d, __aeabi_d2f etc functions even though they
were provided by lib/libm/math.c.

Damien George b4790afdaf tools/mpy-tool.py: Store qstr config values in global config object.
Makes it easier to access them without passing around another dict of the
config values.
2016-09-02 15:09:21 +10:00
Damien George 72ae3c72c7 tools/mpy-tool.py: Support freezing float literals with obj-repr C.
The tool now generates code for freezing floats in obj-repr A, B or C,
with the specific representation detected at compile time using macros.

Damien George 25a42fb6ef tools/mpy-tool.py: Don't strip directories from the frozen source name.
Directories are now supported by the frozen import system (to implement
frozen packages) so we should keep them.
2016-05-23 13:29:03 +01:00
Damien George 9b4c013823 tools/mpy-tool.py: Include .py extension in frozen filename.
So that it can be correctly stat'd when looking for frozen files.

Paul Sokolovsky daa4793578 tools/make-frozen: Update for latest changes in frozen modules support.
Frozen modules are now stored with extensions and with '/' as path
separator. In other words, frozen modules paths stored as they are
in normal filesystem.

Damien George 99b4719357 tools/mpy-tool.py: Add checks for critical configuration vars.
When an mpy file is frozen it must know the values of certain
configuration variables.  This patch provides an explicit check in the
generated C file that the configuration variables are what they are
supposed to be.
2016-05-16 23:13:30 +01:00
Paul Sokolovsky 7b1bf0c308 tools/make-frozen.py: Quick fix to support package-modules.
It allows to "import foo.bar", but not "from foo import bar".

Damien George 0a2e9650f5 py: Add ability to have frozen persistent bytecode from .mpy files.
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY.  This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).
2016-04-13 16:07:47 +01:00
Damien George 0699c6bf9e tools: Add mpy-tool.py, to work with .mpy files.
