From 456a3819a54275384d5a3367bf8497587ee85f85 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 24 Oct 2005 11:24:31 +0000 Subject: [PATCH] * elflink.c (elf_link_input_bfd): Don't use linker_mark and SEC_EXCLUDE to test for sections dropped from output. Instead, use bfd_section_removed_from_list on normal sections. Don't attempt to handle symbols with unknown reserved section indices. * linker.c (_bfd_generic_link_output_symbols): Don't use linker_mark to test for symbols belonging to dropped sections. Do allow absolute symbols. --- bfd/ChangeLog | 10 ++++++++++ bfd/elflink.c | 24 +++++++++--------------- bfd/linker.c | 9 +++------ 3 files changed, 22 insertions(+), 21 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 231e6daf8a..fcb1fbc049 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,5 +1,15 @@ 2005-10-24 Alan Modra + * elflink.c (elf_link_input_bfd): Don't use linker_mark and + SEC_EXCLUDE to test for sections dropped from output.
