bfd/
* elf32-vax.c (elf_vax_check_relocs): Handle the visibility
attribute.
(elf_vax_relocate_section): Likewise.
gas/
* config/tc-vax.c (md_estimate_size_before_relax): Accept
indirect symbol references in the PIC mode and emit a
PC-relative relocation instead of a GOT/PLT one. Likewise
for symbols known to be hidden at this point.
