From d099120c64430117a80fc95c0bff2da9ff5d8657 Mon Sep 17 00:00:00 2001 From: Doug Kwan Date: Fri, 19 Mar 2010 19:11:21 +0000 Subject: 2010-03-19 Doug Kwan * arm.cc (Stub_table::Stub_table): Initialize new data members Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_. (Stub_table::add_reloc_stub): Assign stub offset and update Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_. (Stub_table::reloc_stubs_size_, Stub_table::reloc_stubs_addralign_): New data members. (Stub_table::update_data_size_and_addralign): Use Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_ instead of going over all reloc stubs. (Stub_table::finalize_stubs): Do not assign reloc stub offsets. * stringpool.cc (Stringpool_template::Stringpool_template): Initialize Stringpool_template::offset_ to size of Stringpool_char. (Stringpool_template::new_key_offset): Remove code to initialize Stringpool_template::offset_. * stringpool.h (Stringpool_template::set_no_zero_null): Set Stringpool_template::offset_ to zero. --- gold/ChangeLog | 19 +++++++++++++++++++ gold/arm.cc | 47 +++++++++++++++++++---------------------------- gold/stringpool.cc | 5 +---- gold/stringpool.h | 4 +++- 4 files changed, 42 insertions(+), 33 deletions(-) diff --git a/gold/ChangeLog b/gold/ChangeLog index 8a92513..aa933e5 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,3 +1,22 @@ +2010-03-19 Doug Kwan + + * arm.cc (Stub_table::Stub_table): Initialize new data members + Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_. + (Stub_table::add_reloc_stub): Assign stub offset and update + Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_. + (Stub_table::reloc_stubs_size_, Stub_table::reloc_stubs_addralign_): + New data members. + (Stub_table::update_data_size_and_addralign): Use + Stub_table::reloc_stubs_size_ and Stub_table::reloc_stubs_addralign_ + instead of going over all reloc stubs. + (Stub_table::finalize_stubs): Do not assign reloc stub offsets. + * stringpool.cc (Stringpool_template::Stringpool_template): Initialize + Stringpool_template::offset_ to size of Stringpool_char. + (Stringpool_template::new_key_offset): Remove code to initialize + Stringpool_template::offset_. + * stringpool.h (Stringpool_template::set_no_zero_null): Set + Stringpool_template::offset_ to zero. + 2010-03-15 Doug Kwan * stringpool.cc (Stringpool_template::Stringpool_template): Initialize diff --git a/gold/arm.cc b/gold/arm.cc index e331fd3..016b2cc 100644 --- a/gold/arm.cc +++ b/gold/arm.cc @@ -868,8 +868,9 @@ class Stub_table : public Output_data { public: Stub_table(Arm_input_section* owner) - : Output_data(), owner_(owner), reloc_stubs_(), cortex_a8_stubs_(), - arm_v4bx_stubs_(0xf), prev_data_size_(0), prev_addralign_(1) + : Output_data(), owner_(owner), reloc_stubs_(), reloc_stubs_size_(0), + reloc_stubs_addralign_(1), cortex_a8_stubs_(), arm_v4bx_stubs_(0xf), + prev_data_size_(0), prev_addralign_(1) { } ~Stub_table() @@ -902,6 +903,15 @@ class Stub_table : public Output_data const Stub_template* stub_template = stub->stub_template(); gold_assert(stub_template->type() == key.stub_type()); this->reloc_stubs_[key] = stub; + + // Assign stub offset early.
