Peter Maydell f48d1fe391 target-arm: Correctly handle 'sub pc, pc, 1' for ARMv6 ... In the ARM v6 architecture, 'sub pc, pc, 1' is not an interworking branch, so the computed new value is written to r15 as a normal value. The architecture says that in this case, bits [1:0] of the value written must be ignored if we are in ARM mode (or bit [0] ignored if in Thumb mode); this is a change from the ARMv4/v5 specification that behaviour is UNPREDICTABLE. Use the correct mask on the PC value when doing a non-interworking store to PC. A popular library used on RaspberryPi uses this instruction as part of a trick to determine whether it is running on ARMv6 or ARMv7, and we were mishandling the sequence.
