From 2cc9ed14fae1b288bbdbd9b102b2cbc9a29bf348 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 25 Aug 2021 20:24:18 +0930 Subject: [GOLD] Output_data_got create entry method addends This patch makes all the Output_data_got methods that create new entries accept an optional addend. PR 28192 * output.h (Output_data_got::add_global): Add optional addend parameter. Update comment. Delete overload without addend. (Output_data_got::add_global_plt): Likewise. (Output_data_got::add_global_tls): Likewise. (Output_data_got::add_global_with_rel): Likewise. (Output_data_got::add_global_pair_with_rel): Likewise. (Output_data_got::add_local_plt): Likewise. (Output_data_got::add_local_tls): Likewise. (Output_data_got::add_local_tls_pair): Likewise. (Output_data_got::reserve_local): Likewise. (Output_data_got::reserve_global): Likewise. (Output_data_got::Got_entry): Include addend in global sym constructor. Delete local sym constructor without addend. * output.cc (Output_data_got::add_global): Add addend param, pass to got handling methods. (Output_data_got::add_global_plt): Likewise. (Output_data_got::add_global_with_rel): Likewise. (Output_data_got::add_global_pair_with_rel): Likewise. (Output_data_got::add_local_plt): Likewise. (Output_data_got::add_local_tls_pair): Likewise. (Output_data_got::reserve_local): Likewise. (Output_data_got::reserve_global): Likewise. --- gold/output.cc | 77 ++++++++++++++++++++++++++++++++-------------------------- 1 file changed, 43 insertions(+), 34 deletions(-) (limited to 'gold/output.cc') diff --git a/gold/output.cc b/gold/output.cc index 75f54f0..c5f7eef 100644 --- a/gold/output.cc +++ b/gold/output.cc @@ -1461,15 +1461,15 @@ Output_data_got::Got_entry::write( template bool -Output_data_got::add_global( - Symbol* gsym, - unsigned int got_type) +Output_data_got::add_global(Symbol* gsym, + unsigned int got_type, + uint64_t addend) { - if (gsym->has_got_offset(got_type)) + if (gsym->has_got_offset(got_type, addend)) return false; - unsigned int got_offset = this->add_got_entry(Got_entry(gsym, false)); - gsym->set_got_offset(got_type, got_offset); + unsigned int got_offset = this->add_got_entry(Got_entry(gsym, false, addend)); + gsym->set_got_offset(got_type, got_offset, addend); return true; } @@ -1478,13 +1478,14 @@ Output_data_got::add_global( template bool Output_data_got::add_global_plt(Symbol* gsym, - unsigned int got_type) + unsigned int got_type, + uint64_t addend) { - if (gsym->has_got_offset(got_type)) + if (gsym->has_got_offset(got_type, addend)) return false; - unsigned int got_offset = this->add_got_entry(Got_entry(gsym, true)); - gsym->set_got_offset(got_type, got_offset); + unsigned int got_offset = this->add_got_entry(Got_entry(gsym, true, addend)); + gsym->set_got_offset(got_type, got_offset, addend); return true; } @@ -1497,14 +1498,15 @@ Output_data_got::add_global_with_rel( Symbol* gsym, unsigned int got_type, Output_data_reloc_generic* rel_dyn, - unsigned int r_type) + unsigned int r_type, + uint64_t addend) { - if (gsym->has_got_offset(got_type)) + if (gsym->has_got_offset(got_type, addend)) return; unsigned int got_offset = this->add_got_entry(Got_entry()); - gsym->set_got_offset(got_type, got_offset); - rel_dyn->add_global_generic(gsym, r_type, this, got_offset, 0); + gsym->set_got_offset(got_type, got_offset, addend); + rel_dyn->add_global_generic(gsym, r_type, this, got_offset, addend); } // Add a pair of entries for a global symbol to the GOT, and add @@ -1517,18 +1519,19 @@ Output_data_got::add_global_pair_with_rel( unsigned int got_type, Output_data_reloc_generic* rel_dyn, unsigned int r_type_1, - unsigned int r_type_2) + unsigned int r_type_2, + uint64_t addend) { - if (gsym->has_got_offset(got_type)) + if (gsym->has_got_offset(got_type, addend)) return; unsigned int got_offset = this->add_got_entry_pair(Got_entry(), Got_entry()); - gsym->set_got_offset(got_type, got_offset); - rel_dyn->add_global_generic(gsym, r_type_1, this, got_offset, 0); + gsym->set_got_offset(got_type, got_offset, addend); + rel_dyn->add_global_generic(gsym, r_type_1, this, got_offset, addend); if (r_type_2 != 0) rel_dyn->add_global_generic(gsym, r_type_2, this, - got_offset + got_size / 8, 0); + got_offset + got_size / 8, addend); } // Add an entry for a local symbol plus ADDEND to the GOT.
