gdb/
* 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.
