Paul Sokolovsky c0a8374103 gc: Don't segfault if gc_realloc() fails. 2014-02-11 15:34:32 +02:00
Paul Sokolovsky af19cbd201 gc: Make debug output configurable, revamp test function.
Test function needs to be called by something else. Test heap size reduced so
its dump fits on a screenful of a typical terminal.

Damien George d3ebe4829d Factor and simplify Makefile's and mpconfig, part 2. 2014-01-07 15:20:33 +00:00
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).
