PR30794, PowerPC gold: internal error in add_output_section_to_load
Caused by commit 5a97377e5513, specifically this code added to
Target_powerpc::do_relax
+ if (parameters->options().output_is_position_independent())
+ this->rela_dyn_size_
+ = this->rela_dyn_section(layout)->current_data_size();
The problem here is that if .rela.dyn isn't already created then the
call to rela_dyn_section creates it, and as this comment in
Target_powerpc::do_finalize_sections says:
// Annoyingly, we need to make these sections now whether or
// not we need them. If we delay until do_relax then we
// need to mess with the relaxation machinery checkpointing.
We can't be creating sections in do_relax.
PR 30794
* powerpc.cc (Target_powerpc::do_relax): Only set rela_dyn_size_
for size == 64, and assert that rela_dyn_ already exists.
Tidy code setting plt_thread_safe, which also only needs to be
set when size == 64 for ELFv1.
