bunnei c51b23b052 Merge pull request #559 from lioncash/clean 
arm: Some cleanup. Also fixed the initial ARM mode that is emulated.
 2015-02-11 12:02:35 -05:00
Lioncash c94c41f95a arm: Get rid of some magic constants. Specify proper ARM mode. 
Initially, we were starting the emulator in USER26MODE, which is incorrect, this should be USER32MODE.

Lioncash 93cd199633 arm: Change some more constants into enums 2015-02-11 10:14:20 -05:00
archshift ef24e72b26 Asserts: break/crash program, fit to style guide; log.h->assert.h 
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

Lioncash 088fab743f arm: Remove TRUE/FALSE defines 
- Removed the Debug parameter from ARMul_State since it isn't used.
- Changed ARMul_CoProInit to a void function. It always returned true.

Lioncash a86d5e2752 vfp: Normalize accumulator for multiply accumulate instructions 2015-02-10 08:16:26 -05:00
Kevin Hartman 5fcbfc06eb Scheduler refactor Pt. 1 
* Simplifies scheduling logic, specifically regarding thread status. It should be much clearer which statuses are valid
for a thread at any given point in the system.
* Removes dead code from thread.cpp.
* Moves the implementation of resetting a ThreadContext to the corresponding core's implementation.

Other changes:
* Fixed comments in arm interfaces.
* Updated comments in thread.cpp
* Removed confusing, useless, functions like MakeReady() and ChangeStatus() from thread.cpp.
* Removed stack_size from Thread. In the CTR kernel, the thread's stack would be allocated before thread creation.

bunnei 4d36a6a255 Merge pull request #536 from lioncash/dead 
vfp: Throw out unused code
 2015-02-04 14:57:00 -05:00
Lioncash 82e8f25fe7 vfp: Fix VCVT 
These variants exclusively read from the single precision regs and write to double-precision registers
Fixes issues where converted values would be way off from what they should be due to the results being stored in the wrong registers.
