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.
