Damien George c8f78bc280 py: VM never throws an exception, instead returns a status and value.
Addresses issue #290, and hopefully sets up things to allow generators
throwing exceptions, etc.

Damien George fb083ea986 py: mp_execute_byte_code has 2 arg arrays, for more efficient default params. 2014-02-01 18:29:40 +00:00
Damien George 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.

Damien George 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.

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).
