bfd/
* bfd-in.h (bfd_elf32_arm_set_target_relocs): Add "bfd *"
argument and extra last argument.
* bfd-in2.h: Regenerate.
* elf32-arm.c (elf32_arm_obj_tdata): Add no_enum_size_warning
member.
(bfd_elf32_arm_set_target_relocs): Add "bfd *" argument and
extra last argument. Set no_enum_size_warning appropriately.
(elf32_arm_merge_eabi_attributes): Improve enum sizes
diagnostic, suppressing it when no_enum_size_warning dictates.
ld/
* ld.texinfo: Document --no-enum-size-warning.
* emultempl/armelf.em (no_enum_size_warning): New.
(arm_elf_create_output_section_statements): Correct typo
in comment. Pass no_enum_size_warning to
bfd_elf32_arm_set_target_relocs.
(PARSE_AND_LIST_PROLOGUE): Define OPTION_NO_ENUM_SIZE_WARNING.
(PARSE_AND_LIST_OPTIONS): Document --no-enum-size-warning.
(PARSE_AND_LIST_ARGS_CASES): Add OPTION_NO_ENUM_SIZE_WARNING
