(xcoff_loader_info): Add auto_export_flags. bfd/ * bfd-in.h (bfd_xcoff_size_dynamic_sections): Replace the bfd_boolean export_defineds parameter with an unsigned int auto_export_flags parameter. * bfd-in2.h: Regenerate. * xcofflink.c (xcoff_archive_contains_shared_object_p): New function, split out from xcoff_build_ldsyms. (xcoff_covered_by_expall_p): New function. (xcoff_auto_export_p): New function, split out from xcoff_build_ldsyms but with extra code to handle -bexpfull and -bexpall. (xcoff_mark_auto_exports): New function. (xcoff_build_ldsyms): Use xcoff_auto_export_p to decide whether a function should be automatically exported. (bfd_xcoff_size_dynamic_sections): Replace the export_defineds parameter with an auto_export_flags parameter. Update ldinfo accordingly. Use xcoff_mark_auto_exports to mark all automatically- exported symbols. ld/ * emultempl/aix.em (auto_export_flags): New variable. (explicit_auto_export_flags): Likewise. (OPTION_EXPALL, OPTION_EXPFULL): New enum values. (OPTION_NOEXPALL, OPTION_NOEXPFULL): Likewise. (gld${EMULATION_NAME}_add_options): Add -bexpall, -bexpfull, -bnoexpall and -bnoexpfull. (gld${EMULATION_NAME}_handle_option): Handle them. (gld${EMULATION_NAME}_before_allocation): Update the call to bfd_size_dynamic_sections. ld/testsuite/ * ld-powerpc/aix-export-1-all.dd, ld-powerpc/aix-export-1-full.dd, ld-powerpc/aix-export-1a.s, ld-powerpc/aix-export-1b.s: New tests. * ld-powerpc/aix52.exp: Run them. --- include/coff/ChangeLog | 5 +++++ include/coff/xcoff.h | 7 +++++-- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/include/coff/ChangeLog b/include/coff/ChangeLog index 09cd87322..ba5fa3fe0 100644 --- a/include/coff/ChangeLog +++ b/include/coff/ChangeLog @@ -1,3 +1,8 @@ +2009-03-14 Richard Sandiford + + * xcoff.h (XCOFF_EXPALL, XCOFF_EXPFULL): New flags. + (xcoff_loader_info): Add auto_export_flags. + 2009-03-14 Richard Sandiford * internal.h (C_AIX_WEAKEXT): New macro. diff --git a/include/coff/xcoff.h b/include/coff/xcoff.h index 4f9f7edee..4439dc99b 100644 --- a/include/coff/xcoff.h +++ b/include/coff/xcoff.h @@ -394,6 +394,9 @@ struct xcoff_link_hash_table asection *special_sections[XCOFF_NUMBER_OF_SPECIAL_SECTIONS]; }; +/* These flags indicate which of -bexpall and -bexpfull are in effect. */ +#define XCOFF_EXPALL 1 +#define XCOFF_EXPFULL 2 /* This structure is used to pass information through xcoff_link_hash_traverse. */ @@ -409,8 +412,8 @@ struct xcoff_loader_info /* Link information structure. */ struct bfd_link_info *info; - /* Whether all defined symbols should be exported. */ - bfd_boolean export_defineds; + /* A mask of XCOFF_EXPALL and XCOFF_EXPFULL flags. */ + unsigned int auto_export_flags; /* Number of ldsym structures. */ size_t ldsym_count; -- 2.43.5
