* alpha-nat.c (fetch_aout_core_registers): Rename from
fetch_core_registers. (fetch_elf_core_registers): New function. (supply_gregset): Use ALPHA_REGSET_BASE. (supply_fpregset): Likewise. (fill_fpregset): Likewise. (alpha_aout_core_fns): Rename from alpha_core_fns. (alpha_elf_core_fns): New. * config/alpha/alpha-linux.mh (NATDEPFILES): solib.o not osfsolib.o. Disable MMALLOC. * config/alpha/nm-linux.h (SVR4_SHARED_LIBS): Define if ELF. (TARGET_ELF64): Likewise. (ALPHA_REGSET_BASE): New. * config/alpha/nm-osf.h (ALPHA_REGSET_BASE): New. * config/alpha/tm-alphalinux.h: Include tm-sysv4.h. * solib.c (elf_locate_base): Add TARGET_ELF64 support. (info_sharedlibary_command): Likewise. * configure.host: Match alpha*. * configure.tgt: Likewise.
