5d509ecace Allow max stack checking to be used with -flto build by determining top 
of stack in a different way.

55f33240f3 all: Use the name MicroPython consistently in comments 
There were several different spellings of MicroPython present in comments,
when there should be only one.

f91493c97e Measure and report maximum stack usage. (#175) 
Add max stack usage tracking, visible via debug module ustack.
Add separate cpp flag for enabling modules: MICROPY_DEBUG_MODULES

88b449a8cd Fix broken mp_stack_check: force mp_stack_ctrl_init() and mp_stack_usage() not to be inlined even with -flto 2017-06-04 22:05:55 -04:00

12fa5b3a66 Switch exception throwing to mp_raise helpers. It saves a little code space each time to share the call. 2017-02-24 15:13:07 +01:00

1d5d4f49d9 py/stackctrl: Add mp_stack_set_top() to explicitly set stack top value. 
Useful for embedded targets with fixed stack layout.

7f1c98177b vm: Support strict stackless mode, with proper exception reporting. 
I.e. in this mode, C stack will never be used to call a Python function,
but if there's no free heap for a call, it will be reported as
RuntimeError (as expected), not MemoryError.

e8432b3c72 stackctrl: Encode "recursion depth exceeded" message as qstr. 
So corresponding exception can be thrown even under tight memory conditions.

b4b10fd350 py: Put all global state together in state structures. 
This patch consolidates all global variables in py/ core into one place,
in a global structure.  Root pointers are all located together to make
GC tracing easier and more efficient.

4abff7500f py: Change uint to mp_uint_t in runtime.h, stackctrl.h, binary.h. 
Part of code cleanup, working towards resolving issue #50.

23668698cb py: Add portable framework to query/check C stack usage. 
Such mechanism is important to get stable Python functioning, because Python
function calling is handled with C stack. The idea is to sprinkle
STACK_CHECK() calls in places where there can be C recursion.

TODO: Add more STACK_CHECK()'s.
