--- Comment #4 from Alan Modra <amodra at gmail dot com> --- Apparently the set of people who care about ia64 and the set of people who know enough to fix this bug are disjoint. So ia64 has never had a working --as-needed. --as-needed was implemented originally in 2004 and working for most targets around 2006. As noted by the original reporter, the problem is that elfNN_ia64_link_hash_entry carries on-the-side data, elfNN_ia64_dyn_sym_info. This on-the-side data can be free'd or modified when adding symbols. So enough state would need to be kept about the original elfNN_ia64_dyn_sym_info for it to be restored. The hook to do these tricks is elf_backend_data.notice_as_needed which will need implementing in the ia64 backend if 2.29 --as-needed is to be fixed. Alternatively, rewrite the generic --as-needed support to check whether a library is needed without modifying symbol state.. The good news is that this problem should disappear with 2.30, since check_relocs (which is where the on-the-side data is created) runs after symbols have been resolved. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
