Support for Xtensa emitter and assembler, and upgraded F4 and F7 STM HAL

This release adds support for the Xtensa architecture as a target for the
native emitter, as well as Xtensa inline assembler.  The int.from_bytes
and int.to_bytes methods now require a second argument (the byte order)
per CPython (only "little" is supported at this time).  The "readall"
method has been removed from all stream classes that used it; "read" with
no arguments should be used instead.  There is now support for importing
packages from compiled .mpy files.  Test coverage is increased to 96%.

The generic I2C driver has improvements: configurable clock stretching
timeout, "stop" argument added to readfrom/writeto methods, "nack"
argument added to readinto, and write[to] now returns num of ACKs
received.  The framebuf module now handles 16-bit depth (generic colour
format) and has hline, vline, rect, line methods.  A new utimeq module is
added for efficient queue ordering defined by modulo time (to be
compatible with time.ticks_xxx functions).  The pyboard.py script has been
modified so that the target board is not reset between scripts or commands
that are given on a single command line.

For the stmhal port the STM Cube HAL has been upgraded: Cube F4 HAL to
v1.13.1 (CMSIS 2.5.1, HAL v1.5.2) and Cube F7 HAL to v1.1.2.  There is a
more robust pyb.I2C implementation (DMA is now disabled by default, can be
enabled via an option), and there is an implementation of machine.I2C with
robust error handling and hardware acceleration on F4 MCUs.  It is now
recommended to use machine.I2C instead of pyb.I2C.  The UART class is now
more robust with better handling of errors/timeouts.  There is also more
accurate VBAT and VREFINT measurements for the ADC.  New boards that are
supported include: NUCLEO_F767ZI, STM32F769DISC and NUCLEO_L476RG.

For the esp8266 port select/poll is now supported for sockets using the
uselect module.  There is support for native and viper emitters, as well
as an inline assembler (with limited iRAM for storage of native functions,
or the option to store code to flash).  There is improved software I2C
with a slight API change: scl/sda pins can be specified as positional only
when "-1" is passed as the first argument to indicate the use of software
I2C.  It is recommended to use keyword arguments for scl/sda.  There is
very early support for over-the-air (OTA) updates using the yaota8266
project.

Damien George b528e9a428 py/builtinimport: Fix bug when importing names from frozen packages.
The commit d9047d3c8a introduced a bug
whereby "from a.b import c" stopped working for frozen packages.  This is
because the path was not properly truncated and became "a//b".  Such a
path resolves correctly for a "real" filesystem, but not for a search in
the list of frozen modules.
2017-01-08 20:17:23 +11:00
Scott Shawcroft e52fbf2e6a Add time.struct_time support. 2017-01-05 14:00:48 -08:00
Damien George 343b4189b0 py/mkrules.mk: Add MPY_CROSS_FLAGS option to pass flags to mpy-cross.
So that ports can pass their own custom options to mpy-cross.

Damien George ea6a958393 py/objint: Simplify mp_int_format_size and remove unreachable code.
One never needs to format integers with a base larger than 16 (but code
can be easily extended beyond this value if needed in the future).
2016-12-28 12:46:20 +11:00

Damien George c2dd494bd9 py/parsenum: Simplify and generalise decoding of digit values.
This function should be able to parse integers with any value for the
base, because it is called by int('xxx', base).

Paul Sokolovsky 25f44c19f1 cc3200: Re-add support for UART REPL (MICROPY_STDIO_UART setting).
UART REPL support was lost in os.dupterm() refactorings, etc. As
os.dupterm() is there, implement UART REPL support at the high level -
if MICROPY_STDIO_UART is set, make default boot.py contain os.dupterm()
call for a UART. This means that changing MICROPY_STDIO_UART value will
also require erasing flash on a module to force boot.py re-creation.

Paul Sokolovsky cf96be60dc py/misc.h: Typo fix in comment. 2016-12-27 01:05:30 +03:00
Damien George c305ae3243 py/lexer: Permanently disable the mp_lexer_show_token function.
The lexer is very mature and this debug function is no longer used.  If
it's really needed one can uncomment it and recompile.
2016-12-22 10:49:54 +11:00
Damien George f4aebafe7a py/lexer: Remove unnecessary check for EOF in lexer's next_char func.
This check always fails (ie chr0 is never EOF) because the callers of this
function never call it past the end of the input stream.  And even if they
did it would be harmless because 1) reader.readbyte must continue to
return an EOF char if the stream is exhausted; 2) next_char would just
count the subsequent EOF's as characters worth 1 column.

Damien George e4af712125 py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.
And also simplify it to remove the check for small int.  This can be done
because this function is only ever called if the argument is not a small
int.

Damien George 7318949c46 py/modbuiltins: Remove unreachable code. 2016-12-20 14:00:59 +11:00
Scott Shawcroft 427d33c706 atmel-samd: Add help() and remove mem_info functions from smallest builds to make room. 2016-12-19 16:38:35 -08:00
Sebastian Plamauer 1598e44231 atmel-samd: Add preliminary support for UART 2016-12-19 13:03:50 -08:00
Damien George de9cd00b39 py/compile: Add an extra pass for Xtensa inline assembler.
It needs an extra pass to compute the size of the constant table for the
l32r instructions.

Damien George 7f1da0a03b py: Add MICROPY_KBD_EXCEPTION config option to provide mp_kbd_exception.
Defining and initialising mp_kbd_exception is boiler-plate code and so the
core runtime can provide it, instead of each port needing to do it
themselves.

The exception object is placed in the VM state rather than on the heap.

Paul Sokolovsky 403c93053e py/mpconfig.h: Enable MICROPY_PY_SYS_EXIT by default.
sys.exit() is an important function to terminate a program. In particular,
the testsuite relies on it to skip tests (i.e. any other functionality may
be disabled, but sys.exit() is required to at least report that properly).

Damien George e8f2db7da3 py/runtime: Zero out fs_user_mount array in mp_init.
There's no need to force ports to copy-and-paste this initialisation
code.  If FSUSERMOUNT is enabled then this zeroing out must be done.

Damien George e83f140463 py/mpz: Remove unreachable code in mpn_or_neg functions. 2016-12-14 10:39:41 +11:00
Damien George d9047d3c8a py/builtinimport: Support importing packages from compiled .mpy files.
This patch ensures that __init__.mpy files are imported if their
containing directory is imported as a package.

Damien George a3c61004c2 py/binary: Do zero extension when storing a value larger than word size. 2016-12-12 15:00:06 +11:00
Paul Sokolovsky 9d787de2a1 py/objint: from_bytes, to_bytes: Require byteorder arg, require "little".
CPython requires byteorder arg, make uPy compatible. As we support only
"little", error out on anything else.

Damien George 93ee6603b1 py/asm: Fix x86 and ARM assemblers due to recent code refactoring. 2016-12-09 22:54:45 +11:00
Damien George 155fdc74d5 py/asm: Remove need for dummy_data when doing initial assembler passes.
For all but the last pass the assembler only needs to count how much space
is needed for the machine code, it doesn't actually need to emit anything.
The dummy_data just uses unnecessary RAM and without it the code is not
any more complex (and code size does not increase for Thumb and Xtensa
archs).

Damien George e920bab976 py/emitinline: Move common code for end of final pass to compiler.
This patch moves some common code from the individual inline assemblers to
the compiler, the code that calls the emit-glue to assign the machine code
to the functions scope.
2016-12-09 21:23:17 +11:00
Damien George dd53b12193 py/emitinline: Move inline-asm align and data methods to compiler.
These are generic methods that don't depend on the architecture and so
can be handled directly by the compiler.
2016-12-09 20:54:54 +11:00
Damien George a7fd786a1f py/emitinline: Embed entire asm struct instead of a pointer to it.
This reduces fragmentation, and memory use by 1 word.  But more
importantly it means the emit_inline_asm_t struct now "derives" from
mp_asm_base.
