From d21f123b0ead1806416cf0dafae12bec4cca8920 Mon Sep 17 00:00:00 2001 From: Cary Coutant <ccoutant@gmail.com> Date: Mon, 11 Jan 2016 23:57:44 -0800 Subject: [PATCH] Fix internal error when applying TLSDESC relocations with no TLS segment. gold/ PR gold/19353 * aarch64.cc (Target_aarch64::relocate_tls): Don't insist that we have a TLS segment for GD-to-IE optimization. * i386.cc (Target_i386::tls_gd_to_ie): Remove tls_segment parameter. Adjust all calls. (Target_i386::tls_desc_gd_to_ie): Likewise. (Target_i386::relocate_tls): Don't insist that we have a TLS segment for TLSDESC GD-to-IE optimizations. * x86_64.cc (Target_x86_64::tls_gd_to_ie): Remove tls_segment parameter. Adjust all calls. (Target_x86_64::tls_desc_gd_to_ie): Likewise. (Target_x86_64::relocate_tls): Don't insist that we have a TLS segment for TLSDESC GD-to-IE optimizations. --- gold/ChangeLog | 16 ++++++++++++++++ gold/aarch64.cc | 6 ------ gold/i386.cc | 14 ++------------ gold/x86_64.cc | 14 ++------------ 4 files changed, 20 insertions(+), 30 deletions(-) Index: binutils-2.25.0/gold/aarch64.cc =================================================================== --- binutils-2.25.0.orig/gold/aarch64.cc +++ binutils-2.25.0/gold/aarch64.cc @@ -3689,12 +3689,6 @@ Target_aarch64<size, big_endian>::Reloca } if (tlsopt == tls::TLSOPT_TO_IE) { - if (tls_segment == NULL) - { - gold_assert(parameters->errors()->error_count() > 0 - || issue_undefined_symbol_error(gsym));
