      objfun: Add local header. · f26a3071
      Paul Sokolovsky authored
      This follows pattern already used for objtuple, etc.: objfun.h's content
      is not public - each and every piece of code should not have access to it.
      It's not private either - with out architecture and implementation language
      (C) it doesn't make sense to keep implementation of each object strictly
      private and maintain cumbersome accessors. It's "local" - intended to be
      used by a small set of "friend" (in C++ terms) objects.

      py: Big improvements to inline assembler. · 87210876
      Damien George authored
      Improved the Thumb assembler back end.  Added many more Thumb
      instructions to the inline assembler.  Improved parsing of assembler
      instructions and arguments.  Assembler functions can now be passed the
      address of any object that supports the buffer protocol (to get the
      address of the buffer).  Added an example of how to sum numbers from
      an array in assembler.

      py: Change compile order for default positional and keyword args. · 69b89d21
      Damien George authored
      This simplifies the compiler a little, since now it can do 1 pass over
      a function declaration, to determine default arguments.  I would have
      done this originally, but CPython 3.3 somehow had the default keyword
      args compiled before the default position args (even though they appear
      in the other order in the text of the script), and I thought it was
      important to have the same order of execution when evaluating default
      arguments.  CPython 3.4 has changed the order to the more obvious one,
      so we can also change.

      py: Put n_state for bytecode in the bytecode prelude. · bee17b00
      Damien George authored
      Rationale: setting up the stack (state for locals and exceptions) is
      really part of the "code", it's the prelude of the function.  For
      example, native code adjusts the stack pointer on entry to the function.
      Native code doesn't need to know n_state for any other reason.  So
      putting the state size in the bytecode prelude is sensible.
      
      It reduced ROM usage on STM by about 30 bytes :)  And makes it easier to
      pass information about the bytecode between functions.

      Implement ROMable modules. Add math module. · 0c36da0b
      Damien George authored
      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).

      Add pin mapping code. · 51dabac0
      Dave Hylands authored
      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.

      py: VM never throws an exception, instead returns a status and value. · c8f78bc2
      Damien George authored
      Addresses issue #290, and hopefully sets up things to allow generators
      throwing exceptions, etc.

      Implement proper exception type hierarchy. · c5966128
      Damien George authored
      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.

      Change mp_obj_type_t.name from const char * to qstr. · a71c83a1
      Damien George authored
      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.
