Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Alexander Steffen ebb9396274 esp8266,minimal,pic16bit: Use size_t for mp_builtin_open argument.
py/builtin.h declares mp_builtin_open with the first argument of type
size_t.  Make all implementations conform to this declaration.

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
    esp8266: +340
     cc3200: +128

Damien George e75fd3a8e9 minimal/main: Make Cortex-M vector table constant. 2017-04-18 10:17:24 +10:00
Damien George 4c307bfba1 all: Move BYTES_PER_WORD definition from ports to py/mpconfig.h
It can still be overwritten by a port in mpconfigport.h but for almost
all cases one can use the provided default.

Damien George b6c7e4b143 all: Use full path name when including mp-readline/timeutils/netutils.
This follows the pattern of how all other headers are now included, and
makes it explicit where the header file comes from.  This patch also
removes -I options from Makefile's that specify the mp-readline/timeutils/
netutils directories, which are no longer needed.

Damien George 92cd000842 minimal/Makefile: Change C standard from gnu99 to c99. 2017-03-23 15:41:38 +11:00
Krzysztof Blazewicz 75589272ef all/Makefile: Remove -ansi from GCC flags, its ignored anyway.
The -ansi flag is used for C dialect selection and it is equivalent to -std=c90.
Because it goes right before -std=gnu99 it is ignored as for conflicting flags
GCC always uses the last one.

Paul Sokolovsky a4dbb4230a minimal/Makefile: Split rule for firmware.bin generation. 2016-10-22 22:01:44 +03:00
Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.

Delio Brignoli e2ac8bb3f1 py: Add MICROPY_USE_INTERNAL_PRINTF option, defaults to enabled.
This new config option allows to control whether MicroPython uses its own
internal printf or not (if not, an external one should be linked in).
Accompanying this new option is the inclusion of lib/utils/printf.c in the
core list of source files, so that ports no longer need to include it
themselves.

Damien George 675d1c9c60 ports: Remove typedef of machine_ptr_t, it's no longer needed.
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation.  So we can now remove this unused typedef,
to simplify the mpconfigport.h file.

Damien George 593ffdd976 minimal: For frozen bytecode generation, add dependency of qstr file. 2016-04-16 13:20:02 +01:00
Damien George f9448ddc2c minimal: Add example of frozen persistent bytecode (.mpy file).
frozentest.py is frozen into the binary as frozen bytecode.  The .mpy
file is included so that there is no dependency on the cross compiler.

Damien George 6eb17c31a9 ports: Disable async/await on bare-arm, minimal, pic16bit, cc3200.
It costs 1188 bytes of code on Thumb 2 archs.

Damien George 54729247e1 minimal: Add enough code to run minimal build on STM32F4xx hardware.
Minimal support code for a Cortex-M CPU is added, along with set-up
code for an STM32F4xx MCU, including a UART for a REPL.  Tested on
a pyboard.  Code size is 77592 bytes.

Paul Sokolovsky 73ff0687f2 lib/utils/printf: Move from stmhal/ .
This file contains various MicroPython-specific helper functions, so isn't
good fit for lib/libc/.

Paul Sokolovsky 0ec51441de stmhal: pyexec.c is common module, move to lib/utils/ . 2015-10-31 19:35:10 +03:00
Damien George 731f359292 all: Add py/mphal.h and use it in all ports.
py/mphal.h contains declarations for generic mp_hal_XXX functions, such
as stdio and delay/ticks, which ports should provide definitions for.  A
port will also provide mphalport.h with further HAL declarations.

Paul Sokolovsky 4a9eac20b9 minimal: Use mp_hal_ticks_ms(). 2015-10-29 20:07:16 +03:00
Paul Sokolovsky 0dbd928cee Makefiles: Remove duplicate object files when linking.
Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.

Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

Paul Sokolovsky e0f5df579b all: Make netutils.h available to all ports by default.
Generally, ports should inherit INC from py.mk, append to it, not
overwrite it. TODO: Likely should do the same for other vars too.

Damien George 90b1cc5103 minimal: Tune parser chunk allocation policy for very small heap. 2015-10-02 00:33:26 +01:00
Damien George 58e0f4ac50 py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.
With this patch parse nodes are allocated sequentially in chunks.  This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.

Saves roughly 20% of RAM during parse stage.

Paul Sokolovsky 22ff397fb1 py: Add MICROPY_PY_BUILTINS_FILTER, disable for minimal ports.
Saves 320 bytes on x86.

Damien George 7a26e4f484 minimal: Use 1 byte for qstr hash, to make port more minimal. 2015-08-02 20:54:58 +01:00
Damien George c4b592d379 bare-arm, minimal, qemu-arm: Make do_str() take parse-input-kind as arg.
The do_str() function is provided essentially as documentation to show
how to compile and execute a string.  This patch makes do_str take an
extra arg to specify how the string should be interpreted: either as a
single line (ie from a REPL) or as multiple lines (ie from a file).
2015-06-22 22:38:47 +01:00
Damien George 06593fb0f2 py: Use a wrapper to explicitly check self argument of builtin methods.
Previous to this patch a call such as list.append(1, 2) would lead to a
seg fault.  This is because list.append is a builtin method and the first
argument to such methods is always assumed to have the correct type.

Now, when a builtin method is extracted like this it is wrapped in a
checker object which checks the the type of the first argument before
calling the builtin function.

This feature is contrelled by MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG and
is enabled by default.

See issue #1216.

Damien George c98c128fe8 pyexec: Make raw REPL work with event-driven version of pyexec.
esp8266 port now has working raw and friendly REPL, as well as working
soft reset (CTRL-D at REPL, or raise SystemExit).

tools/pyboard.py now works with esp8266 port.

Damien George 5aa311d330 py: Add attrtuple object, for space-efficient tuples with attr access.
If you need the functionality of a namedtuple but will only make 1 or a
few instances, then use an attrtuple instead.

Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

Paul Sokolovsky 3a84c8b58d string0.c: Move from stmhal/ to lib/. 2015-04-05 21:57:55 +03:00
Damien George 42e0c59308 py: Add MICROPY_COMP_{DOUBLE,TRIPLE}_TUPLE_ASSIGN config options.
These allow to fine-tune the compiler to select whether it optimises
tuple assignments of the form a, b = c, d and a, b, c = d, e, f.
Sensible defaults are provided.

Damien George 601c814603 minimal: Allow to compile without defining MICROPY_HAL_H. 2015-02-13 15:26:53 +00:00
Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.

This patch adds that feature in all places.  This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

Paul Sokolovsky 640e0b221e py: Implement very simple frozen modules support.
Only modules (not packages) supported now. Source modules can be converted
to frozen module structures using tools/make-frozen.py script.
