2000-09-05 Alan Modra <alan@linuxcare.com.au>
* elf64-hppa.c (elf64_hppa_check_relocs): Handle R_PARISC_PCREL12F.
(elf64_hppa_size_dynamic_sections): Remove the FIXME at bfd_zalloc
comment.
From David Huggins-Daines <dhd@linuxcare.com>
* elf64-hppa.c (elf64_hppa_check_relocs): Fix a warning.
(elf64_hppa_mark_exported_functions): Set dyn_h->st_shndx.
(elf64_hppa_link_output_symbol_hook): Test dyn_h->st_shndx has
been updated in finish_dynamic_symbol before modifying function
symbol.
* elf-hppa.h (elf_hppa_howto_table): Restructure into groups of
eight entries. Replace NULL with bfd_elf_generic_reloc. Add
R_PARISC_GNU_VTENTRY, R_PARISC_GNU_VTINHERIT and R_PARISC_PCREL12F.
