af1ae30399 objexcept: Add mp_obj_exception_get_value() convenience function. 
This gets "value" of exceptions in the sense as it's defined for
StopIteration.value (i.e. args[0] or None).

TODO: This really should be inline function.

962b1cd1b1 objgenerator: Implement return with value and .close() method. 
Return with value gets converted to StopIteration(value). Implementation
keeps optimizing against creating of possibly unneeded exception objects,
so there're considerable refactoring to implement these features.

f909034400 py: Implement support for "except Exception as var" clause. 
For this, needed to implement DELETE_NAME bytecode (because var bound
in except clause is automatically deleted at its end).

"When an exception has been assigned using as target, it is cleared at
the end of the except clause."

57207b8818 objint_mpz: Quick&dirty implementation of bitwise operations. 
Made solely to unbreak int-long.py test which in turn uncovered thinko
with implementation of inplace ops. On mpz level, bitwise ops implemented
only for same-sign numbers, and are not efficient (unconditional calling of
mpn_cmp() is apparently superfluous).

a8d31b28bc emitbc: Correct buffer sizes for varlen int encoding. 
Assuming we have truncating (floor) division, way to do ceiling division
by N is to use formula (x + (N-1)) / N. Specifically, 63 bits, if stored
7 bits per byte, require exactly 9 bytes. 64 bits overflow that and require
10 bytes.

51dabac096 Add pin mapping code. 
This commit also introduces board directories and moves board
specific config into the appropriate board directory.

boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
and hand-tweaked.

make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
and boards/BOARD-NAME/pins.csv as input and generates the file
build/pins_BOARD_NAME.c

The generated pin file for PYBOARD4 looks like this:
https://gist.github.com/dhylands/9063231

The generated pins file includes all of the supported alternate
functions, and includes upsupported alternate functions as comments.

See the commnet block at the top of stm/pin_map.c for details on
how to use the pin mapper.

I also went ahead and modified stm/gpio.c to use the pin mapper.

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.

the bad argument), and printing objects that don't supply a .print method.

feature can take path from environment). If it's not explicitly initialized,

382e8eeea2 vm: Add basic implementation of END_FINALLY opcode. 
Allows to have nested try blocks with except filters.

TODO: Don't add END_FINALLY's exception re-raise points to traceback.

09a0c64bce py: Improve __bool__ and __len__ dispatch; add slots for them. 2014-01-30 10:05:33 +00:00

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.

d0691ccaec py: Simplify fastn in VM; reduce size of unique code struct. 
We still have FAST_[0,1,2] byte codes, but they now just access the
fastn array (before they had special local variables).  It's now
simpler, a bit faster, and uses a bit less stack space (on STM at least,
which is most important).

The only reason now to keep FAST_[0,1,2] byte codes is for compressed
byte code size.
