(struct gdbarch_tdep): Add fp_model.
* arm-tdep.c (arm_gdbarch_init): Set fp_model in tdep. Defer setting
up floating-point conversions until we know the floating-point model
in use by the inferior. Don't complain about being unable to
determine the ABI of the inferior when we don't have one.
(arm_extract_return_value): Support different floating-point models.
(arm_store_return_value): Likewise.
* armnbsd-tdep.c (arm_netbsd_aout_init_abi): Set fp_model in tdep to
ARM_FLOAT_SOFT.
(arm_netbsd_elf_init_abi): Set fp_model to ARM_FLOAT_SOFT_VFP.
* gdbarch.c gdbarch.h: Regenerate.
* breakpoint.c (create_longjmp_breakpoint): Always compile this
function.
(breakpoint_reset): Test GET_LONGJMP_TARGET_P().
* infrun.c (GET_LONGJMP_TARGET): Delete default definition.
(handle_inferior_event): Test GET_LONGJMP_TARGET_P().
* arm-tdep.h (struct gdbarch_tdep): Add jb_pc and jb_elt_size fields.
* arm-tdep.c (arm_get_longjmp_target): New function.
(arm_gdbarch_init): Initialize jb_pc to -1. If ABI handler changes
this to a positive value register arm_get_longjmp_target as the
longjmp handler.
* arm-linux-tdep.c (arm_get_longjmp_target): Delete.
(arm_linux_init_abi): Set up longjmp description in tdep.
* armnbsd-nat.c (get_longjmp_target): Delete.
* armnbsd-tdep.c (arm_netbsd_init_abi_common): Set up longjmp
description in tdep.
* config/arm/tm-nbsd.h (JB_ELEMENT_SIZE, JB_PC): Delete.
(get_longjmp_target): Delete declaration.
(GET_LONGJMP_TARGET): Delete.
* config/arm/tm-linux.h (arm_get_longjmp_target): Delete declaration.
(GET_LONGJMP_TARGET): Delete.
(struct gdbarch_tdep): New structure.
(LOWEST_PC): Provide a default.
(arm_gdbarch_register_os_abi): Declare new function.
* arm-tdep.c (arm_abi_names): New array.
(process_note_abi_tag_sections): New function.
(get_elfosabi): New function.
(arm_gdbarch_register_os_abi): New function.
(arm_gdbarch_init): Try to determine the ABI of the inferior. If
support for that ABI has been built in, then call the appropriate
configuration routine. Use gdbarch_num_regs() to get the number
of registers.
(arm_dump_tdep): New function.
(arm_init_abi_eabi_v1, arm_init_abi_eabi_v2, arm_init_abi_apcs): New
place-holder functions.
(_initialize_arm_tdep): Register them.
* config/arm/tm-arm.h (LOWEST_PC): Delete.
* armnbsd-tdep.c: New file.
* Makefile.in (armnbsd-tdep.o): Add dependencies.
* config/arm/nbsd.mt (TDEPFILES): Add it.
* config/arm/tm-nbsd.h (LOWEST_PC): Delete.
* armnbsd-nat.c: Include regcache.h.
* Makefile.in (armnbsd-nat.o): Update dependency list.
* arm-tdep.c (arm_get_next_pc): Use printf_filtered for error message.
