2009-04-01 Richard Sandiford <r.sandiford@uk.ibm.com>
* xcofflink.c (xcoff_link_hash_table): Moved from include/coff/xcoff.h.
2009-04-01 Richard Sandiford <r.sandiford@uk.ibm.com>
* xcofflink.c (xcoff_link_create_extra_sections): Don't create
a .loader section for relocatable links.
(xcoff_need_ldrel_p): New function.
(xcoff_mark): Use it.
(bfd_xcoff_link_count_reloc): Only count loader relocs if there's
a loader section.
(xcoff_build_ldsym): New function, split out from...
(xcoff_build_ldsyms): ...here. Rename to...
(xcoff_post_gc_symbol): ...this. Only export symbols, and only
call xcoff_build_ldsym, if there's a loader section.
(xcoff_build_loader_section): New function, extracted verbatim from...
(bfd_xcoff_size_dynamic_sections): ...here. Only call it if
there's a loader section. Only add an __rtinit loader symbol
if there's a loader section. Update after above name change.
(xcoff_symbol_section, xcoff_create_ldrel): New functions.
(bfd_link_input_bfd): Use xcoff_need_ldrel_p, xcoff_symbol_section
and xcoff_create_ldrel.
(xcoff_write_global_symbol): Use xcoff_create_ldrel.
(xcoff_reloc_link_order): Likewise, but only call it if there's
a loader section. Use xcoff_symbol_section.
(_bfd_xcoff_bfd_final_link): Only use fdinfo.ldrel and fdinfo.ldsym
if there's a loader section.
2009-04-01 Richard Sandiford <rdsandiford@googlemail.com>
* xcofflink.c (bfd_link_input_bfd): Fix buffer overrun.
