py: Implement break/continue from an exception with finally.
...
Still todo: break/continue from within the finally block itself.
2014-02-01 20:08:18 +00:00
90750029df
Implement default function arguments (for Python functions).
...
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.

08d075592f
py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int.
...
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.

py: Implement 'not' in compiler, and improve rt_is_true.

py: Improve freeing of emitters in mp_compile.
...
There can be multiple emitters allocated during compile (eg byte code
and native).
2014-01-24 22:42:28 +00:00
f46d87a30d
Add support for freeing code emitter objects at the end of compilation.

py: Use C99 way of variable macro arguments.
...
Addresses Issue #207 .
2014-01-23 00:34:21 +00:00
00208ce194
py: Change macro var args in parser to be C99 compliant.
2014-01-23 00:00:53 +00:00
600ae734cf
py: Implement break and continue byte codes, and add tests.
...
Also fixes a bug in the for-in-range optimiser.
I hope to remove break and continue byte codes in the future and just
use jump (if possible).
2014-01-21 23:48:04 +00:00
55baff4c9b
Revamp qstrs: they now include length and hash.
...
Can now have null bytes in strings. Can define ROM qstrs per port using
qstrdefsport.h
2014-01-21 21:40:13 +00:00
cbd2f7482c
py: Add module/function/class name to exceptions.
...
Exceptions know source file, line and block name.
Also tidy up some debug printing functions and provide a global
flag to enable/disable them.
2014-01-19 11:48:48 +00:00
08335004cf
Add source file name and line number to error messages.
...
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.
2014-01-18 23:24:36 +00:00

compile_for_stmt_optimised_range(): Properly handle negative & unknown steps.
...
If step is not constant, in first approximation, we can't apply optimization,
(well, we could, but need a special case for this).
2014-01-11 01:00:21 +02:00
71c5181a8d
Convert Python types to proper Python type hierarchy.
...
Now much more inline with how CPython does types.
2014-01-04 20:21:15 +00:00

Split qstr into pools, and put initial pool in ROM.
...
Qstr's are now split into a linked-list of qstr pools. This has 2
benefits: the first pool can be in ROM (huge benefit, since we no longer
use RAM for the core qstrs), and subsequent pools use m_new for the next
pool instead of m_renew (thus avoiding a huge single table for all the
qstrs).
Still would be better to use a hash table, but this scheme takes us part
of the way (eventually convert the pools to hash tables).
Also fixed bug with import.
Also improved the way the module code is referenced (not magic number 1
anymore).
2014-01-04 15:57:35 +00:00
e67ed5d285
Improve configurability for native x64/thumb emitter.
...
With MICROPY_EMIT_X64 and MICROPY_EMIT_THUMB disabled, the respective
emitters and assemblers will not be included in the code. This can
significantly reduce binary size for unix version.
2014-01-04 13:55:24 +00:00

Change mp_compile so that it returns a function object for the module.

py: remove depedence on strcat and stpcpy.
...
This fixes Issue #29 , and means the core is no longer dependent on
string functions, except strlen.

Change memory allocation API to require size for free and realloc.
2013-12-29 19:33:23 +00:00
d99b05282d
Change object representation from 1 big union to individual structs.
...
A big change. Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object). This scheme follows CPython. Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.
Also change name prefix, from py_ to mp_ (mp for Micro Python).
