From 4fc5075cebc9c76053b5ff683ab75c9e8b46ca1a Mon Sep 17 00:00:00 2001 From: David Holsgrove Date: Wed, 27 Feb 2013 13:56:11 +1000 Subject: [PATCH 05/52] upstream change to garbage collection sweep causes mb regression Upstream change for PR13177 now clears the def_regular during gc_sweep of a section. (All other archs in binutils/bfd/elf32-*.c received an update to a warning about unresolvable relocations - this warning is not present in binutils/bfd/elf32-microblaze.c, but this warning check would not prevent the error being seen) The visible issue with this change is when running a c++ application in Petalinux which links libstdc++.so for exception handling it segfaults on execution. This does not occur if static linking libstdc++.a, so its during the relocations for a shared lib with garbage collection this occurs Signed-off-by: David Holsgrove --- bfd/elflink.c | 1 - 1 file changed, 1 deletion(-) diff --git a/bfd/elflink.c b/bfd/elflink.c index 998b72f228..2daf8fdf6a 100644 --- a/bfd/elflink.c +++ b/bfd/elflink.c @@ -6372,7 +6372,6 @@ elf_gc_sweep_symbol (struct elf_link_hash_entry *h, void *data) inf = (struct elf_gc_sweep_symbol_info *) data; (*inf->hide_symbol) (inf->info, h, TRUE); - h->def_regular = 0; h->ref_regular = 0; h->ref_regular_nonweak = 0; } -- 2.17.1
