INT_REGISTER_SIZE. (arm_linux_push_arguments): Use TARGET_DOUBLE_BIT instead of FP_REGISTER_VIRTUAL_SIZE. * arm-tdep.c (arm_make_sigtramp_cache): Use register_size instead of DEPRECATED_REGISTER_RAW_SIZE. (arm_register_type): Add gdbarch argument. (arm_register_raw_size, arm_register_virtual_size): Delete. (arm_register_byte, arm_extract_return_value) (arm_store_return_value, arm_get_longjmp_target): Update references to INT_REGISTER_RAW_SIZE and FP_REGISTER_RAW_SIZE. (arm_gdbarch_init): Likewise. Don't set deprecated_register_raw_size, deprecated_register_virtual_size, deprecated_max_register_raw_size, deprecated_max_register_virtual_size, or deprecated_max_register_virtual_type. Do set register_type. * arm-tdep.h (ARM_MAX_REGISTER_RAW_SIZE) (ARM_MAX_REGISTER_VIRTUAL_SIZE, INT_REGISTER_VIRTUAL_SIZE) (FP_REGISTER_VIRTUAL_SIZE): Delete. (INT_REGISTER_RAW_SIZE): Rename to INT_REGISTER_SIZE. (FP_REGISTER_RAW_SIZE): Rename to FP_REGISTER_SIZE. * arm-linux-tdep.c (ARM_NBSD_JB_ELEMENT_SIZE): Define to INT_REGISTER_SIZE. * remote-rdp.c (remote_rdp_fetch_register): Use MAX_REGISTER_SIZE. (remote_rdp_store_register): Likewise.
