e063aa3bd8 * armemu.h (INSN_SIZE): New macro. 
(SET_ABORT): Save CPSR in SPSR and set LR.
* armemu.c (ARMul_Emulate, isize): Set to INSN_SIZE.
(WriteR15, WriteSR15): Do not discard bit 1 in Thumb mode.
* arminit.c (ARMul_Abort): Use new SETABORT and INSN_SIZE.

13b6dd6f68 * armemu.c (LoadSMult): Use WriteR15() to discard the least 
significant bits of PC.

892c6b9d8f * armemu.h (WRITEDESTB): New macro. 
* armemu.c (ARMul_Emulate26, bl): Use WriteR15Branch() to
modify PC.  Moved the existing logic...
(WriteR15Branch): ... here.  New function.
(WriteR15, WriteSR15): Drop the two least significant bits.
(LoadSMult): Use WriteR15Branch() to modify PC.
(LoadMult): Use WRITEDESTB() instead of WRITEDEST().

4ef2594f4e * armemu.h (PSR_FBITS, PSR_SBITS, PSR_XBITS, PSR_CBITS): New. 
(SETPSR_F, SETPSR_S, SETPSR_X, SETPSR_C): New macros.
(SETPSR, SET_INTMODE, SETCC): Removed.
* armsupp.c (ARMul_FixCPSR, ARMul_FixSPSR): Do not test bit
mask.  Use SETPSR_* to modify PSR.
(ARMul_SetCPSR): Load all bits from value.
* armemu.c (ARMul_Emulate, msr): Do not test bit mask.

e62263b8ec * armemu.c (ARMul_Emulate): Compute writeback value before 
loading, since the offset register may be the destination
register.
