In commit6085d6f6, Z0 packet is disabled in aarch64 GDBserver if the inferior is 32-bit or there may be multiple inferiors, because Z0 packet isn't supported for arm then. Recently, Z0 packet is supported in arm target, so we don't have such limitation in aarch64 GDBserver, that is to say, aarch64 GDBserver can use Z0 packet in multi-arch/multi-inferior debugging when the inferior's arch is arm. Part of this patch is to revert6085d6f6, and the rest of the patch is to move some breakpoint related arm_* functions into linux-aarch32-low.c in order to share them between arm and aarch64. This patch is regression tested on aarch64-linux for debugging both aarch64 programs and arm programs respectively. gdb/gdbserver: 2015-12-07 Yao Qi <yao.qi@linaro.org> * configure.srv: Append arm.o to srv_tgtobj for aarch64*-*-linux* target. * linux-aarch32-low.c (arm_abi_breakpoint): New macro. Moved from linux-arm-low.c. (arm_eabi_breakpoint, arm_breakpoint): Likewise. (arm_breakpoint_len, thumb_breakpoint): Likewise. (thumb_breakpoint_len, thumb2_breakpoint): Likewise. (thumb2_breakpoint_len): Likewise. (arm_is_thumb_mode, arm_breakpoint_at): Likewise. (arm_breakpoint_kinds): Likewise. (arm_breakpoint_kind_from_pc): Likewise.

(arm_breakpoint_kind_from_current_state): Declare. (arm_breakpoint_at): Declare. * linux-aarch64-low.c (aarch64_sw_breakpoint_from_kind): Call arm_sw_breakpoint_from_kind if process is 32-bit. (aarch64_breakpoint_kind_from_pc): New function. (aarch64_breakpoint_kind_from_current_state): New function. (the_low_target): Initialize fields breakpoint_kind_from_pc and breakpoint_kind_from_current_state. * linux-arm-low.c (arm_breakpoint_kinds): Move to linux-aarch32-low.c. (arm_abi_breakpoint, arm_eabi_breakpoint): Likewise. (arm_breakpoint, arm_breakpoint_len): Likewise. (thumb_breakpoint, thumb_breakpoint_len): Likewise. (thumb2_breakpoint, thumb2_breakpoint_len): Likewise. (arm_is_thumb_mode): Likewise. (arm_breakpoint_at): Likewise. (arm_breakpoint_kind_from_pc): Likewise. (arm_sw_breakpoint_from_kind): Likewise. (arm_breakpoint_kind_from_current_state): Likewise. Revert: 2015-08-04 Yao Qi <yao.qi@linaro.org> * linux-aarch64-low.c (aarch64_supports_z_point_type): Return 0 for Z_PACKET_SW_BP if it may be used in multi-arch debugging. * server.c (extended_protocol): Remove "static". * server.h (extended_protocol): Declare it.
