From d21f123b0ead1806416cf0dafae12bec4cca8920 Mon Sep 17 00:00:00 2001 From: Cary Coutant 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/aarch64.cc | 6 ------ gold/i386.cc | 14 ++------------ gold/x86_64.cc | 14 ++------------ 4 files changed, 20 insertions(+), 30 deletions(-) diff --git a/gold/aarch64.cc b/gold/aarch64.cc index 20f2f4f..5ad061b 100644 --- a/gold/aarch64.cc +++ b/gold/aarch64.cc @@ -7422,12 +7422,6 @@ Target_aarch64::Relocate::relocate_tls( } if (tlsopt == tls::TLSOPT_TO_IE) { - if (tls_segment == NULL) - { - gold_assert(parameters->errors()->error_count() > 0 - || issue_undefined_symbol_error(gsym)); - return aarch64_reloc_funcs::STATUS_BAD_RELOC; - } return tls_desc_gd_to_ie(relinfo, target, rela, r_type, view, psymval, got_entry_address, address); diff --git a/gold/i386.cc b/gold/i386.cc index 82886d4..a7168a8 100644 --- a/gold/i386.cc +++ b/gold/i386.cc @@ -668,7 +668,6 @@ class Target_i386 : public Sized_target<32, false> // Do a TLS General-Dynamic to Initial-Exec transition. inline void tls_gd_to_ie(const Relocate_info<32, false>*, size_t relnum, - Output_segment* tls_segment, const elfcpp::Rel<32, false>&, unsigned int r_type, elfcpp::Elf_types<32>::Elf_Addr value, unsigned char* view, @@ -687,7 +686,6 @@ class Target_i386 : public Sized_target<32, false> // transition. inline void tls_desc_gd_to_ie(const Relocate_info<32, false>*, size_t relnum, - Output_segment* tls_segment, const elfcpp::Rel<32, false>&, unsigned int r_type, elfcpp::Elf_types<32>::Elf_Addr value, unsigned char* view, @@ -3054,7 +3052,7 @@ Target_i386::Relocate::relocate_tls(const Relocate_info<32, false>* relinfo, } if (optimized_type == tls::TLSOPT_TO_IE) { - this->tls_gd_to_ie(relinfo, relnum, tls_segment, rel, r_type, + this->tls_gd_to_ie(relinfo, relnum, rel, r_type, got_offset, view, view_size); break; } @@ -3116,13 +3114,7 @@ Target_i386::Relocate::relocate_tls(const Relocate_info<32, false>* relinfo, } if (optimized_type == tls::TLSOPT_TO_IE) { - if (tls_segment == NULL) - { - gold_assert(parameters->errors()->error_count() > 0 - || issue_undefined_symbol_error(gsym)); - return; - } - this->tls_desc_gd_to_ie(relinfo, relnum, tls_segment, rel, r_type, + this->tls_desc_gd_to_ie(relinfo, relnum, rel, r_type, got_offset, view, view_size); break; } @@ -3354,7 +3346,6 @@ Target_i386::Relocate::tls_gd_to_le(const Relocate_info<32, false>* relinfo, inline void Target_i386::Relocate::tls_gd_to_ie(const Relocate_info<32, false>* relinfo, size_t relnum, - Output_segment*, const elfcpp::Rel<32, false>& rel, unsigned int, elfcpp::Elf_types<32>::Elf_Addr value, @@ -3449,7 +3440,6 @@ inline void Target_i386::Relocate::tls_desc_gd_to_ie( const Relocate_info<32, false>* relinfo, size_t relnum, - Output_segment*, const elfcpp::Rel<32, false>& rel, unsigned int r_type, elfcpp::Elf_types<32>::Elf_Addr value, diff --git a/gold/x86_64.cc b/gold/x86_64.cc index 3cfc064..4ad5afc 100644 --- a/gold/x86_64.cc +++ b/gold/x86_64.cc @@ -816,7 +816,6 @@ class Target_x86_64 : public Sized_target // Do a TLS General-Dynamic to Initial-Exec transition. inline void tls_gd_to_ie(const Relocate_info*, size_t relnum, - Output_segment* tls_segment, const elfcpp::Rela&, unsigned int r_type, typename elfcpp::Elf_types::Elf_Addr value, unsigned char* view, @@ -835,7 +834,6 @@ class Target_x86_64 : public Sized_target // Do a TLSDESC-style General-Dynamic to Initial-Exec transition. inline void tls_desc_gd_to_ie(const Relocate_info*, size_t relnum, - Output_segment* tls_segment, const elfcpp::Rela&, unsigned int r_type, typename elfcpp::Elf_types::Elf_Addr value, unsigned char* view, @@ -3733,7 +3731,7 @@ Target_x86_64::Relocate::relocate_tls( if (optimized_type == tls::TLSOPT_TO_IE) { value = target->got_plt_section()->address() + got_offset; - this->tls_gd_to_ie(relinfo, relnum, tls_segment, rela, r_type, + this->tls_gd_to_ie(relinfo, relnum, rela, r_type, value, view, address, view_size); break; } @@ -3800,14 +3798,8 @@ Target_x86_64::Relocate::relocate_tls( } if (optimized_type == tls::TLSOPT_TO_IE) { - if (tls_segment == NULL) - { - gold_assert(parameters->errors()->error_count() > 0 - || issue_undefined_symbol_error(gsym)); - return; - } value = target->got_plt_section()->address() + got_offset; - this->tls_desc_gd_to_ie(relinfo, relnum, tls_segment, + this->tls_desc_gd_to_ie(relinfo, relnum, rela, r_type, value, view, address, view_size); break; @@ -3973,7 +3965,6 @@ inline void Target_x86_64::Relocate::tls_gd_to_ie( const Relocate_info* relinfo, size_t relnum, - Output_segment*, const elfcpp::Rela& rela, unsigned int, typename elfcpp::Elf_types::Elf_Addr value, @@ -4085,7 +4076,6 @@ inline void Target_x86_64::Relocate::tls_desc_gd_to_ie( const Relocate_info* relinfo, size_t relnum, - Output_segment*, const elfcpp::Rela& rela, unsigned int r_type, typename elfcpp::Elf_types::Elf_Addr value, -- 1.7.1
