3077fbff26 nlr: Add even more optional debugging logging. 
Has to be enabled by manual editing, but at least it's there, as debugging
NLR issues may be weird.

e89cc13e5c nlr: If DEBUG, guard against recursive nlr_push(). 
Pushing same NLR record twice would lead to "infinite loop" in nlr_jump
(but more realistically, it will crash as soon as NLR record on stack is
overwritten).

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.

8a2347723e py: Move global variable nlr_top to one place, in a .c file. 
This reduces dependency on assembler, and allows to consolidate global
variables in the future.

Addresses issue #1022.

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.

bf3366a48b Add missing “assert.h” file header inclusion from “nlr.h” 2014-06-19 18:47:38 +02:00

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/.

f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it. 
Specifically, nlr.h does.

851c856585 nlr.h: As we treat all warnings as errors, can't use #warning. 
And this is not good.

3a83b805fc nlr: Add implementation using setjmp/longjmp. 
Having an optimized asm implementation is good, but if we want portability,
that's it.

26cf55ae05 Add a check for NULL nlr_top in nlr_jump. 
If no nlr_buf has been pushed, and an nlr_jump is called, then control
is transferred to nlr_jump_fail (which should bail out with a fatal
error).

ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging. 
This does not affect code size or performance when debugging turned off.

To address issue #420.
