From c78337f4e6459e18e1d2af95d8e313b9dcb3f097 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(-) Index: gdb-9.2/bfd/elflink.c =================================================================== --- gdb-9.2.orig/bfd/elflink.c +++ gdb-9.2/bfd/elflink.c @@ -6274,7 +6274,6 @@ elf_gc_sweep_symbol (struct elf_link_has 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; }
