Damien George 3926c72dd2 unix: Add target to build "minimal" uPy interpreter. 2015-01-16 18:03:01 +00:00
Damien George d95b519aa1 unix, windows: Don't call mp_unix_mark_exec on windows. 2015-01-14 11:43:51 +00:00
Damien George 2127e9a844 py, unix: Trace root pointers with native emitter under unix port. 
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.

Damien George cd34207409 py: Can compile with -Wmissing-declarations and -Wmissing-prototypes. 2015-01-12 22:30:49 +00:00
Damien George 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.

Damien George 6d7e47087f unix: Prefix includes with py/; remove need for -I../py. 2015-01-01 20:40:19 +00:00
Damien George 969a6b37bf py: Make functions static where appropriate. 2014-12-10 22:08:14 +00:00
Damien George 109c1de015 py: Make gc.enable/disable just control auto-GC; alloc is still allowed. 
gc.enable/disable are now the same as CPython: they just control whether
automatic garbage collection is enabled or not.  If disabled, you can
still allocate heap memory, and initiate a manual collection.

Damien George 40f3c02682 Rename machine_(u)int_t to mp_(u)int_t. 
See discussion in issue #50.

Paul Sokolovsky caa7334141 stackctrl: Add "mp_" prefix. 2014-07-01 02:14:08 +03:00
stijn 5478ed18ea unix: Fix mpconfig.h not being included before misc.h 
This fixes count_lead_ones in misc.h not compiling due to unknown types

stijn de5ce6d461 gc: Use simple cast instead of union to silence compiler 2014-06-22 11:32:32 +02:00
stijn 8abcf666cb windows: Enable GC and implement bss start and end symbols 
The pointers to the bss section are acquired in init.c()
by inspecting the PE header. Works for msvc and mingw.

Paul Sokolovsky a96cc824bd py: Support arm and thumb ARM ISAs, in addition to thumb2. 
These changes were tested with QEMU, and by few people of real hardware.

Paul Sokolovsky 76c8a4c91b unix: Add setjmp-based GC register helper implementation. 
As I suspected for a long time, for x86, register helper doesn't really make
any difference - there's simply not enough register to keep anything in
them for any prolonged time. Anything gets pushed on stack anyway. So, on
x86, uPy passed all tests even with empty reg helper. So, this setjmp
implementation goes as "untested".

Paul Sokolovsky 1d567592b1 unix/gccollect.c: Make Clang workaround apply only to it. Unbreaks gcc builds. 2014-05-28 15:37:22 +03:00
Antonin ENFRUN ceac71f1f5 unix: Add asm statements needed to read registers with clang. Code generated by gcc 4.9.0 is unchanged (same statements, different order). 
Both are inefficient, saving unmodified registers on the stack.

Damien George 04b9147e15 Add license header to (almost) all files. 
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

xbe a36a55d2cf unix: Update comment in gccollect.c 2014-04-11 06:42:17 -07:00
Damien George 4b34c76fd6 Changes to get unix/ port compiling on Cygwin. 2014-04-03 23:51:16 +01:00
xbe c93a22197b unix: Clean up includes. 
Remove unnecessary includes. Add includes that improve portability.
