From 69431babfb54b26000fdcc016323cf811d48e862 Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Tue, 20 Jun 2017 16:18:58 -0700 Subject: 2017-06-20 Eric Christopher * aarch64.cc (scan_reloc_for_stub): Use plt_address_for_global to calculate the symbol value. (scan_reloc_section_for_stubs): Allow stubs to be created for section symbols. (maybe_apply_stub): Handle creating stubs for weak symbols to match the code in scan_reloc_for_stub. --- gold/aarch64.cc | 21 +++++++++------------ 1 file changed, 9 insertions(+), 12 deletions(-) (limited to 'gold/aarch64.cc') diff --git a/gold/aarch64.cc b/gold/aarch64.cc index 33f7abe6b74..11bb48e3b00 100644 --- a/gold/aarch64.cc +++ b/gold/aarch64.cc @@ -3768,8 +3768,7 @@ Target_aarch64::scan_reloc_for_stub( if (gsym->use_plt_offset(arp->reference_flags())) { // This uses a PLT, change the symbol value. - symval.set_output_value(this->plt_section()->address() - + gsym->plt_offset()); + symval.set_output_value(this->plt_address_for_global(gsym)); psymval = &symval; } else if (gsym->is_undefined()) @@ -4002,11 +4001,6 @@ Target_aarch64::scan_reloc_section_for_stubs( psymval = &symval2; } - // If symbol is a section symbol, we don't know the actual type of - // destination.
