2e420aba3c dyncom: Handle the case where PC is the source register for STR/VSTM/VLDM 2015-07-29 10:57:47 -04:00

2182adff9e dyncom: Handle left-operand PC correctly for data-processing ops
This is considered deprecated in the ARM manual (using PC as an operand),
however, this is still able to be executed on the MPCore (which I'm quite
sure would be rare to begin with).

03213f893e dyncom: Remove unnecessary initialization code.
Targeting ARM version variants was only a thing on armemu.

The reset routine also does basically the same thing as NewState.

3257d797e1 dyncom: Remove unnecessary abort-related cruft
Both the MPCore and the ARM9 have the same data abort model (base restored), so differentiating isn't necessary.

c2689b8c2c dyncom: Pass SVC immediates directly.
Previously it would just re-read the already decoded instruction and extract the immediate value.

dc7ac751f2 dyncom: Stub MCRR and MRRC
There's no other coprocessor outside the VFP (which has its own VMOV variants) in which the MPCore can send/retrieve data from.
Stubbed so citra won't crash and burn on the odd chance someone actually tries to use these.
