* elf-hppa.h (elf_hppa_final_link): Fix formatting in comment.
Skip excluded sections in determing __gp value. (elf_hppa_final_link_relocate): Use the symbol's address in R_PARISC_FPTR64 relocations that don't need an opd entry. * elf64-hppa.c (allocate_dynrel_entries): Simplify code. (elf64_hppa_finalize_dynreloc): Likewise. (elf64_hppa_size_dynamic_sections): Move comments and fix typo. (elf64_hppa_finish_dynamic_symbol): Break up assert.
