(struct gdb_osabi_handler): Remove member `arch'. Add member `arch_info'. (gdbarch_register_osabi): Add new argument `machine'. Use ot to construct a `struct bfd_arch_info' and store it in the `struct gdb_osabi_handler' that is created. (gdbarch_init_osabi): Check for compatibility based on machine type and architecture. * osabi.h (gdbarch_register_osabi): Adjust prototype and update comment. * alpha-linux-tdep.c (_initialize_alpha_linux_tdep): Add 0 as second argument in call to gdbarch_register_osabi. * alpha-osf1-tdep.c (_initialize_alpha_osf1_tdep): Likewise. * alphafbsd-tdep.c (_initialize_alphafbsd_tdep): Likewise. * alphanbsd-tdep.c (_initialize_alphanbsd_tdep): Likewise. * arm-linux-tdep.c (_initialize_arm_linux_tdep): Likewise. * arm-tdep.c (_initialize_arm_tdep): Likewise. * armnbsd-tdep.c (_initialize_armnbsd_tdep): Likewise. * hppa-hpux-tdep.c (_initialize_hppa_hpux_tdep): Likewise. * i386-interix-tdep.c (_initialize_i386_interix_tdep): Likewise. * i386-linux-tdep.c (_initialize_i386_linux_tdep): Likewise. * i386-sol2-tdep.c (_initialize_i386_sol2_tdep): Likewise. * i386-tdep.c (_initialize_i386_tdep): Likewise. * i386bsd-tdep.c (_initialize_i386bsd_tdep): Likewise. * i386gnu-tdep.c (_initialize_i386gnu_tdep): Likewise. * i386ly-tdep.c (_initialize_i386lynx_tdep): Renamed from _initialize_i386bsd_tdep and updated likewise. * i386nbsd-tdep.c (_initialize_i386nbsd_tdep): Likewise. * i386obsd-tdep.c (_initialize_i386obsd_tdep): Likewise. * mips-irix-tdep.c (_initialize_mips_irix_tdep): Likewise. * mips-linux-tdep.c (_initialize_mips_linux_tdep): Likewise. * mipsnbsd-tdep.c (_initialize_mipsnbsd__tdep): Likewise. * ns32knbsd-tdep.c (_initialize_ns32kmnsd_tdep): Likewise. * ppc-linux-tdep.c (_initialize_ppc_linux_tdep): Likewise. * ppcnbsd-tdep.c (_initialize_ppcnbsd_tdep): Likewise. * shnbsd-tdep.c (_initialize_shnbsd_tdep): Likewise. * sparcnbsd-tdep.c (_initialize_sparcnbsd_tdep): Likewise.
