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.
