From 8e354058532d48dce19fdf0b2e0653609a69f19e Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Wed, 18 Oct 2017 15:46:57 -0700 Subject: tile: Mark __tls_get_addr in gc_mark_hook TLS_GD_CALL relocations implicitly reference __tls_get_addr. Since elf_gc_mark_hook is called before check_relocs now, we need to call _bfd_generic_link_add_one_symbol to mark __tls_get_addr for garbage collection. * elf32-tilepro.c (tilepro_elf_gc_mark_hook): Call _bfd_generic_link_add_one_symbol to mark __tls_get_addr. * elfxx-tilegx.c (tilegx_elf_gc_mark_hook): Likewise. --- bfd/elf32-tilepro.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'bfd/elf32-tilepro.c') diff --git a/bfd/elf32-tilepro.c b/bfd/elf32-tilepro.c index 7ab60bbacaa..0bdb6c46e8e 100644 --- a/bfd/elf32-tilepro.c +++ b/bfd/elf32-tilepro.c @@ -1864,6 +1864,8 @@ tilepro_elf_gc_mark_hook (asection *sec, dealing with TLS optimization, ought to be !bfd_link_executable (info). */ if (bfd_link_pic (info)) { + struct bfd_link_hash_entry *bh; + switch (ELF32_R_TYPE (rel->r_info)) { case R_TILEPRO_TLS_GD_CALL: @@ -1872,8 +1874,14 @@ tilepro_elf_gc_mark_hook (asection *sec, on this reloc, so the real symbol and section will be gc marked when processing the other reloc.
