This patch allows any given thread to do a proper garbage collection and
scan all the pointers of all active threads.
py: Add MP_STATE_THREAD to hold state specific to a given thread.2016-06-28T10:09:31+00:00Damien Georgedamien.p.george@gmail.com2016-04-22T22:44:56+00:00urn:sha1:330165a2cc9a0d4d5d00f13f851412c25d5f4ed2py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.2015-11-29T14:25:35+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:01:44+00:00urn:sha1:999cedb90ff0827cdb9dfe0e4faa6ebc1739d271
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.
This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.
unix/gccollect: Fallback to setjmp-based register fetching automatically.2015-11-08T14:05:33+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-11-07T20:04:42+00:00urn:sha1:6e68a68d18c53789e5a1179b0c0d83246e562ab6
Now, if we build for an architecture which doesn't have dedicated support
for getting registers for GC scanning, fallback to setjmp-based method
automatically. It's still possible to force setjmp-based implementation
on archs with dedicated support (e.g. for testing, or for peculiar calling
conventions/optimizations).
unix: Add target to build "minimal" uPy interpreter.2015-01-16T18:03:01+00:00Damien Georgedamien.p.george@gmail.com2015-01-11T17:28:27+00:00urn:sha1:3926c72dd2c6c9bfc4840f914be5a55258d3a248unix, windows: Don't call mp_unix_mark_exec on windows.2015-01-14T11:43:51+00:00Damien Georgedamien.p.george@gmail.com2015-01-14T11:43:51+00:00urn:sha1:d95b519aa1160960d4473d1db34bacfcc46a94d6py, unix: Trace root pointers with native emitter under unix port.2015-01-14T00:11:09+00:00Damien Georgedamien.p.george@gmail.com2015-01-14T00:11:09+00:00urn:sha1:2127e9a844ae46cb2149e7c38eb9f4345075f6e4
Native code has GC-heap pointers in it so it must be scanned. But on
unix port memory for native functions is mmap'd, and so it must have
explicit code to scan it for root pointers.

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.
