Reduces by about a factor of 10 on average the amount of RAM needed to
store the line-number to bytecode map in the bytecode prelude.
Using CPython3.4's stdlib for statistics: previously, an average of
13 bytes were used per (bytecode offset, line-number offset) pair, and
now with this improvement, that's down to 1.3 bytes on average.
Large RAM usage before was due to some very large steps in line numbers,
both from the start of the first line in a function way down in the
file, and also functions that have big comments and/or big strings in
them (both cases were significant).
Although the savings are large on average for the CPython stdlib, it
won't have such a big effect for small scripts used in embedded
programming.
Addresses issue #648.

See discussion in issue #50.
|
|
|
|
Also, dump code block in bytes.
|

This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT
See issue #35 for discussion.
|
|
Now of the form MICROPY_PY_*. See issue #35.
|
|
|
|
bytecode is the more widely used. See issue #590.

Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
|
|
Specifically, nlr.h does.
|
|
It's the same as LOAD_CONST_STR.
|
|
|

3 emitter functions are needed only for emitcpy, and so we can #if them
out when compiling with emitcpy support.
Also remove unused SETUP_LOOP bytecode.
|
|
mp_obj_t->subscr now does load/store/delete.
|
|
Should address issue #475.
|
|
|
|
This is necessary to catch all cases where locals are referenced before
assignment. We still keep the _0, _1, _2 versions of LOAD_FAST to help
reduced the byte code size in RAM.
Addresses issue #457.

Needed to reinstate 2 delete opcodes, to specifically check that a local
is not deleted twice.
|
|
At this point, all opcodes are now implemented!
Some del opcodes have been combined with store opcodes, with the value
to store being MP_OBJ_NULL.
|
|
Adding this bytecode allows to remove 4 others related to
function/method calls with * and ** support. Will also help with
bytecodes that make functions/closures with default positional and
keyword args.

show_bc now decodes the prelude correctly. Moved WRITE_FILE stuff from
runtime.c to emitglue.c.
Addresses issue #385.

Remove unnecessary includes. Add includes that improve portability.
|
|
|
|
TODO: De-duplicate DECODE_UINT, etc. definitions.
|
|
|
|
|
|
|
|
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new
special NOT bytecode.
|
|
Still todo: break/continue from within the finally block itself.
|
|
TODO: Decide if we really need separate bytecode for creating functions
with default arguments - we would need same for closures, then there're
keywords arguments too. Having all combinations is a small exponential
explosion, likely we need just 2 cases - simplest (no defaults, no kw),
and full - defaults & kw.

LOAD_METHOD bug was: emitbc did not correctly calculate the amount of
stack usage for a LOAD_METHOD operation.
small int bug was: int was being used to pass small ints, when it should
have been machine_int_t.
|
|
Can now have null bytes in strings. Can define ROM qstrs per port using
qstrdefsport.h
|
|
Exceptions know source file, line and block name.
Also tidy up some debug printing functions and provide a global
flag to enable/disable them.
|
|
|
|
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

Change state layout in VM so the stack starts at state[0] and grows
upwards. Locals are at the top end of the state and number downwards.
This cleans up a lot of the interface connecting the VM to C: now all
functions that take an array of Micro Python objects are in order (ie no
longer in reverse).
Also clean up C API with keyword arguments (call_n and call_n_kw
replaced with single call method that takes keyword arguments). And now
make_new takes keyword arguments.
emitnative.c has not yet been changed to comply with the new order of
stack layout.
