Paul m. p. P 862cc45a9c py/mkrules.mk: Use $(CPP) not $(CC) -E for preprocessor rule. 2019-06-25 15:03:41 +10:00
Damien George 34c04d2319 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.

Yonatan Goldschmidt 7cf26ca4bd py/obj: Optimise small-int comparison to 0 in mp_obj_is_true.
Instead of converting to a small-int at runtime this can be done at compile
time, then we only have a simple comparison during runtime.  This reduces
code size on some ports (e.g -4 on qemu-arm, -52 on unix nanbox), and for
others at least doesn't increase code size.

Damien George 4173950658 mpy-cross: Do not automatically build mpy-cross, rather do it manually.
Building mpy-cross automatically leads to some issues with the build
process and slows it down.  Instead, require it to be built manually.

Damien George a4f1d82757 py/nativeglue: Remove dependency on mp_fun_table in dyn-compiler mode.
mpy-cross uses MICROPY_DYNAMIC_COMPILER and MICROPY_EMIT_NATIVE but does
not actually need to execute native functions, and does not need
mp_fun_table.  This commit makes it so mp_fun_table and all its entries are
not built when MICROPY_DYNAMIC_COMPILER is enabled, significantly reducing
the size of the mpy-cross executable and allowing it to be built on more
machines/OS's.

Sebastien Rinsoz 6cf4e9675b py/mkrules.mk: Remove unnecessary ; in makefile.
This ; make Windows compilation fail with GNU makefile 4.2.1.  It was added
in 0dc85c9f86 as part of a shell if-
statement, but this if-statement was subsequently removed in
23a693ec2d so the semicolon is not needed.

Sebastien Rinsoz a4f4239e95 py: Update makefiles to use $(TOUCH) instead of hard coded "touch".
The variable $(TOUCH) is initialized with the "touch" value in mkenv.mk
like for the other command line tools (rm, echo, cp, mkdir etc).  With
this, for example, Windows users can specify the path of touch.exe.

stijn fb54736bdb py/objarray: Add decode method to bytearray.
Reuse the implementation for bytes since it works the same way regardless
of the underlying type.  This method gets added for CPython compatibility
of bytearray, but to keep the code simple and small array.array now also
has a working decode method, which is non-standard but doesn't hurt.

disabled by default.

Jun Wu 089c9b71d1 py: remove "if (0)" and "if (false)" branches.
Prior to this commit, building the unix port with `DEBUG=1` and
`-finstrument-functions` the compilation would fail with an error like
"control reaches end of non-void function".  This change fixes this by
removing the problematic "if (0)" branches.  Not all branches affect
compilation, but they are all removed for consistency.

Ayke van Laethem 2e516074da py: Implement a module system for external, user C modules.

FROZEN_MPY_DIR) as a make parameter.

Andrew Leech cf22f4793c py: Allow registration of modules at their definition.
During make, makemoduledefs.py parses the current builds c files for
MP_REGISTER_MODULE(module_name, obj_module, enabled_define)

"mp_rom_map_elem_t mp_builtin_module_table[]" in py/objmodule.c

Damien George 1396a026be py: Add support to save native, viper and asm code to .mpy files.
This commit adds support for saving and loading .mpy files that contain
native code (native, viper and inline-asm).  A lot of the ground work was
already done for this in the form of removing pointers from generated
native code.  The changes here are mainly to link in qstr values to the
native code, and change the format of .mpy files to contain native code
blocks (possibly mixed with bytecode).

A top-level summary:

- @micropython.native, @micropython.viper and @micropython.asm_thumb/
  asm_xtensa are now allowed in .py files when compiling to .mpy, and they
  work transparently to the user.

- Entire .py files can be compiled to native via mpy-cross -X emit=native
  and for the most part the generated .mpy files should work the same as
  their bytecode version.

- The .mpy file format is changed to 1) specify in the header if the file
  contains native code and if so the architecture (eg x86, ARMV7M, Xtensa);
  2) for each function block the kind of code is specified (bytecode,
  native, viper, asm).

- When native code is loaded from a .mpy file the native code must be
  modified (in place) to link qstr values in, just like bytecode (see
  py/persistentcode.c:arch_link_qstr() function).

In addition, this now defines a public, native ABI for dynamically loadable
native code generated by other languages, like C.

Damien George 01a1f31f67 py/emitnative: Consolidate where HASCONSTS is set to load-const-obj fun.
Simplifies the code and fixes handling of the Ellipsis const in native code
generation (which also needs the constant table so must set this flag).
2019-03-08 15:53:04 +11:00
Damien George 02cc288edb py: Add independent config for debugging sentinel object values.
The new compile-time option is MICROPY_DEBUG_MP_OBJ_SENTINELS, disabled by
default.  This is to allow finer control of whether this debugging feature
is enabled or not (because, for example, this setting must be the same for
mpy-cross and the MicroPython main code when using native code generation).

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%.
