From ac06287b30ea1b1a49adc0a65e2536a082f33bde Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Wed, 22 Oct 2003 06:58:17 +0000 Subject: [PATCH] bfd/ * elflink.c (_bfd_elf_export_symbol): Adjust for globals and locals field changes. (_bfd_elf_link_assign_sym_version): Likewise. * elflink.h (size_dynamic_sections): Likewise. include/ * bfdlink.h (struct bfd_elf_version_expr): Remove match field. Add wildcard and mask fields. (BFD_ELF_VERSION_C_TYPE): Define. (BFD_ELF_VERSION_CXX_TYPE): Likewise. (BFD_ELF_VERSION_JAVA_TYPE): Likewise. (struct bfd_elf_version_expr_head): New. (struct bfd_elf_version_tree): Add match field. Change type of globals and locals fields to struct bfd_elf_version_expr_head. ld/ * ldlang.c: Include hashtab.h. (lang_vers_match_lang_c, lang_vers_match_lang_cplusplus, lang_vers_match_lang_java): Remove. (lang_vers_match): New function. (lang_new_vers_pattern): Initialize wildcard and mask fields, don't initialize match. (lang_new_vers_node): Use xcalloc. Adjust for globals and locals field type changes. Set match field. (version_expr_head_hash, version_expr_head_eq): New functions. (lang_finalize_version_expr_head): New function. (lang_register_vers_node): Call lang_finalize_version_expr_head. Search in hash table if not wildcard when looking for duplicates. * emultempl/ppc64elf.em (new_vers_pattern): Don't bother with duplicate checking. Initialize all fields of dot_entry from entry with the exception of pattern and next. --- include/ChangeLog | 12 ++++++++++++ include/bfdlink.h | 37 +++++++++++++++++++++++++++++-------- 2 files changed, 41 insertions(+), 8 deletions(-) diff --git a/include/ChangeLog b/include/ChangeLog index 34f66f056..d1e9a1df7 100644 --- a/include/ChangeLog +++ b/include/ChangeLog @@ -1,3 +1,15 @@ +2003-10-22 Jakub Jelinek + + * bfdlink.h (struct bfd_elf_version_expr): Remove match field. + Add wildcard and mask fields. + (BFD_ELF_VERSION_C_TYPE): Define. + (BFD_ELF_VERSION_CXX_TYPE): Likewise. + (BFD_ELF_VERSION_JAVA_TYPE): Likewise. + (struct bfd_elf_version_expr_head): New. + (struct bfd_elf_version_tree): Add match field. + Change type of globals and locals fields + to struct bfd_elf_version_expr_head. + 2003-10-14 Bob Wilson * elf/xtensa.h: Formatting.
