From 5efeedf61e4fe720fd3e9a08e6c91c10abb66d42 Mon Sep 17 00:00:00 2001 From: Cary Coutant Date: Fri, 26 Sep 2014 13:34:27 -0700 Subject: [PATCH] Fix handling of relocations against TLS section symbols. Gold doesn't handle relocations against the section symbol for a TLS section correctly. Instead of using the offset of the section relative to the TLS segment, it uses the address of the actual section. This patch checks for section symbols for TLS sections, and treats them the same as TLS symbols. gold/ PR gold/16773 * object.cc (Sized_relobj_file): Compute value of section symbols for TLS sections the same as TLS symbols. --- gold/ChangeLog | 6 ++++++ gold/object.cc | 4 +++- 2 files changed, 9 insertions(+), 1 deletion(-) diff --git a/gold/ChangeLog b/gold/ChangeLog index 4b39c3f..f71db09 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,3 +1,9 @@ +2014-09-26 Cary Coutant + + PR gold/16773 + * object.cc (Sized_relobj_file): Compute value of section symbols + for TLS sections the same as TLS symbols. + 2014-09-25 Cary Coutant PR gold/17432 diff --git a/gold/object.cc b/gold/object.cc index 03239d8..6ab84ce 100644 --- a/gold/object.cc +++ b/gold/object.cc @@ -2359,7 +2359,9 @@ Sized_relobj_file::compute_final_local_value_internal( lv_out->set_merged_symbol_value(msv); } } - else if (lv_in->is_tls_symbol()) + else if (lv_in->is_tls_symbol() + || (lv_in->is_section_symbol() + && (os->flags() & elfcpp::SHF_TLS))) lv_out->set_output_value(os->tls_offset() + secoffset + lv_in->input_value()); -- 2.7.4
