Add ARM_ to the front of INT_REGISTER_SIZE, FP_REGISTER_SIZE and ARM_VFP_REGISTER_SIZE to make it obvious they are for the Arm target. Move the defines to arch/arm.h No functionality changes. gdb/ChangeLog: * arch/arm-get-next-pcs.c (thumb_get_next_pcs_raw): Use ARM_ defines. * arch/arm-linux.c (arm_linux_sigreturn_next_pc_offset): Likewise. * arch/arm.h (INT_REGISTER_SIZE) Rename from... (ARM_INT_REGISTER_SIZE): ...to this. (ARM_FP_REGISTER_SIZE) (ARM_VFP_REGISTER_SIZE): Add define. * arm-linux-tdep.c (ARM_LINUX_JB_ELEMENT_SIZE) (ARM_LINUX_SIZEOF_GREGSET, arm_linux_supply_gregset) (arm_linux_collect_gregset, supply_nwfpe_register) (collect_nwfpe_register, arm_linux_collect_nwfpe): Use ARM_ defines. * arm-linux-tdep.h (ARM_LINUX_SIZEOF_NWFPE, NWFPE_FPSR_OFFSET) (NWFPE_FPCR_OFFSET, NWFPE_TAGS_OFFSET): Likewise * arm-nbsd-tdep.c (ARM_NBSD_JB_ELEMENT_SIZE): Likewise. * arm-tdep.c (arm_push_dummy_call, arm_extract_return_value) (arm_return_in_memory, arm_store_return_value) (arm_get_longjmp_target, arm_register_g_packet_guesses) (arm_record_ld_st_multiple): Likewise. * arm-tdep.h (FP_REGISTER_SIZE, VFP_REGISTER_SIZE): Remove. * arm-wince-tdep.c (ARM_WINCE_JB_ELEMENT_SIZE): Use ARM_ defines.
