Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Paul Sokolovsky 96ed213320 objfloat: Quick&dirty implementation of float floor division.
TODO: Likely doesn't match Python semantics for negative numbers.

Paul Sokolovsky 864038dab7 objfloat: Make sure that floats always have dot (for C "double" type case).
This matches CPython behavior and hopefully can be treated as general
Python semantics.

Paul Sokolovsky a8e60c1fde objfloat: Missing default: caused incorrect results for unimplemented ops. 2014-03-31 02:23:56 +03:00
Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

Remove unnecessary includes. Add includes that improve portability.

Damien George 9d68e9ccdd py: Implement integer overflow checking for * and << ops.
If operation will overflow, a multi-precision integer is created.

Damien George 8bfec2b538 Rename formatfloat file; remove MICROPY_ENABLE_FLOAT from mpconfigport.h.
MICROPY_ENABLE_FLOAT is automatically set in mpconfig.h if MICROPY_FLOAT_IMPL
is set to a non-zero value.

Dave Hylands ca5a241e48 Add proper floating point printing support. 2014-03-10 00:10:01 -07:00
Damien George 0c36da0b59 Implement ROMable modules. Add math module.
mp_module_obj_t can now be put in ROM.

Configuration of float type is now similar to longint: can now choose
none, float or double as the implementation.

math module has basic math functions.  For STM port, these are not yet
implemented (they are just stub functions).

Damien George 2077397118 py: Put number parsing code together in parsenum.c. 2014-02-22 18:12:43 +00:00
Damien George c5966128c7 Implement proper exception type hierarchy.
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of.  When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).

Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.

Handling of parse error changed to match new exceptions.

mp_const_type renamed to mp_type_type for consistency.

Damien George a71c83a1d1 Change mp_obj_type_t.name from const char * to qstr.
Ultimately all static strings should be qstr.  This entry in the type
structure is only used for printing error messages (to tell the type of
the bad argument), and printing objects that don't supply a .print method.

Damien George 099a9cb575 Remove mp_obj_new_exception_msg_1_arg and _2_arg. 2014-02-12 23:02:19 +00:00
Paul Sokolovsky d5df6cd44a Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.
Some tools do not support local/static symbols (one example is GNU ld map file).
Exposing all functions will allow to do detailed size comparisons, etc.

Also, added bunch of statics where they were missing, and replaced few identity
functions with global mp_identity().

Damien George 9aa2a527b5 py: Tidy up BINARY_OPs; negation done by special NOT bytecode.
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new
special NOT bytecode.
2014-02-01 23:04:09 +00:00
Paul Sokolovsky c1d9bbc345 Implement __bool__ and __len__ via unary_op virtual method for all types.
__bool__() and __len__() are just the same as __neg__() or __invert__(),
and require efficient dispatching implementation (not requiring search/lookup).
type->unary_op() is just the right choice for this short of adding
standalone virtual method(s) to already big mp_obj_type_t structure.

Damien George 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

Damien George 20006dbba9 Make VM stack grow upwards, and so no reversed args arrays.
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.

Damien George 71c5181a8d Convert Python types to proper Python type hierarchy.
Now much more inline with how CPython does types.

Damien 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).
