* arm-tdep.c (arm_frame_is_thumb): New. (arm_pc_is_thumb): Clarify comment. (thumb_analyze_prologue): Remove PC special case. (thumb_scan_prologue): Take a block_addr argument. Use it for find_pc_partial_function. Remove unused variables. (arm_scan_prologue): Use arm_frame_is_thumb. Use the block address for find_pc_partial_function. Remove PC special case. (arm_prologue_prev_register): Add special handling for PC and CPSR. (arm_dwarf2_prev_register, arm_dwarf2_frame_init_reg): New. (arm_get_next_pc): Use arm_frame_is_thumb. (arm_write_pc): Use CPSR_T instead of 0x20. (arm_gdbarch_init): Call dwarf2_frame_set_init_reg. * arm-tdep.h (enum gdb_regnum): Add ARM_CPSR_REGNUM. (CPSR_T): Define. * dwarf2-frame.c (dwarf2_frame_prev_register): Handle DWARF2_FRAME_REG_FN. * dwarf2-frame.h (enum dwarf2_frame_reg_rule): Add DWARF2_FRAME_REG_FN. (struct dwarf2_frame_state_reg): Add FN to loc union. * gdb.arch/thumb-prologue.exp: Do not expect a saved PC.
