bfd/ChangeLog:
* elf32-xtensa.c (elf_xtensa_check_relocs): Remove code to read literal tables and check for relocs outside of literal pools. (elf_xtensa_make_sym_local): Don't clear ELF_LINK_NON_GOT_REF flag. (elf_xtensa_fix_refcounts): Don't check ELF_LINK_NON_GOT_REF or set DF_TEXTREL. (elf_xtensa_size_dynamic_sections): Don't add DT_TEXTREL entry. (elf_xtensa_relocate_section): Read literal tables and check for dynamic relocations in read-only sections and not in literal pools. gas/ChangeLog: * config/tc-xtensa.c (xtensa_post_relax_hook): Create literal tables even when use_literal_section flag is not set.
