oliverschmidt	1c77f6f1d5	- The cc65 assembler variable 'ptr1' (a general zero page pointer) is actually part of the cc65 zero page area so it's a bad idea (tm) to use it in swapping that very area. - The cc65 assembler variable 'sp' (the pointer to the C stack) is actually part of the cc65 zero page area so there's no need to manage it explicitly. Furthermore it is known to reside at the very start of the area so it can be initialized there for new threads.	2007-08-10 10:45:35 +00:00
oliverschmidt	8d3496194f	Added Multithreading support to the cc65 targets based on the Contiki 1.x C64 implementation with the following changes: - Added support for the function parameter. - Removed support for preemption because: - No other current implementation does so. - Preemption support would make the code at least target-dependent or it wouldn't work at all (as on plain Apple2 machines without timer interrupt).	2007-04-21 22:15:45 +00:00

Added Multithreading support to the cc65 targets based on the Contiki 1.x C64 implementation with the following changes:

- Added support for the function parameter.
- Removed support for preemption because:
  - No other current implementation does so.
  - Preemption support would make the code at least target-dependent or it wouldn't work at all (as on plain Apple2 machines without timer interrupt).
