* arm-tdep.h (arm_insert_single_step_breakpoint): Add prototype. * arm-tdep.c (arm_override_mode): New global. (arm_pc_is_thumb): Respect arm_override_mode. Remove single-step execution mode heuristics. (thumb_get_next_pc_raw): Remove INSERT_BKTP argument; always insert second single-step breakpoint if needed, using arm_insert_single_step_breakpoint. (arm_get_next_pc_raw): Remove INSERT_BKTP argument. Only handle ARM execution mode, do not call thumb_get_next_pc_raw. (arm_get_next_pc): Encode execution mode in return value. Call either arm_get_next_pc_raw or thumb_get_next_pc_raw. (arm_insert_single_step_breakpoint): New function. (arm_software_single_step): Call it. * arm-linux-tdep.c (arm_linux_sigreturn_return_addr): Add IS_THUMB argument to return execution mode of sigreturn target. (arm_linux_syscall_next_pc): Use it. (arm_linux_copy_svc): Update call. (arm_linux_software_single_step): Call arm_insert_single_step_breakpoint. gdb/testsuite/ * gdb.arch/thumb-singlestep.S: New file. * gdb.arch/thumb-singlestep.exp: Likewise.
