* Makefile.in (arm_linux_tdep_h): New variable.
(arm-linux-nat.o, arm-linux-tdep.o): Update. * arm-linux-nat.c: Include "arm-linux-tdep.h". (typeNone, typeSingle, typeDouble, typeExtended) (FPWORDS, ARM_CPSR_REGNUM, FPREG, FPA11) (fetch_nwfpe_single, fetch_nwfpe_double, fetch_nwfpe_none) (fetch_nwfpe_extended, fetch_nwfpe_register, store_nwfpe_single) (store_nwfpe_double, store_nwfpe_extended, store_nwfpe_register): Delete. (fetch_fpregister, fetch_fpregs, store_fpregister, store_fpregs): Use gdb_byte buffers, NWFPE_FPSR_OFFSET, supply_nwfpe_register, and collect_nwfpe_register. (fill_gregset, supply_gregset, fill_fpregset, supply_fpregset): Use new regset functions. * arm-linux-tdep.c: Include "regset.h" and "arm-linux-tdep.h". (arm_apcs_32): New declaration. (ARM_LINUX_SIZEOF_GREGSET, arm_linux_supply_gregset) (arm_linux_collect_gregset, typeNone, typeSingle, typeDouble) (typeExtended, supply_nwfpe_register, collect_nwfpe_register) (arm_linux_supply_nwfpe, arm_linux_collect_nwfpe) (arm_linux_regset_from_core_section): New. (arm_linux_init_abi): Register arm_linux_regset_from_core_section. * arm-linux-tdep.h: New file. * arm-tdep.h (struct regset): Declare. (struct gdbarch_tdep): Add gregset, fpregset members. * config/arm/linux.mh (NATDEPFILES): Remove corelow.o and core-regset.o. * config/arm/linux.mt (TDEPFILES): Add corelow.o.
