From Richard Earnshaw <rearnsha@arm.com>: * arm-tdep.c (arm_software_single_step): New function. Implements software single-stepping for ARM targets. (arm_get_next_pc, thumb_get_next_pc, bitcount, shifted_reg_val): Only needed for software single-stepping. * config/arm/tm-arm.h: Activate SOFTWARE_SINGLE_STEP_P.
