2023-06-23[GOLD] PowerPC64 huge branch dynamic relocsAlan Modra1-61/+38
PowerPC64 gold and ld.bfd implement an indirect branch trampoline, used when the destination of a branch exceeds a bounce through another "b" instruction. When generating PIEs or shared libraries, the addresses need dynamic relocations. This was implemented in gold using a dedicated relocation section, but this means the relative relocations for these addresses are not sorted properly with other dynamic relative relocations: gold doesn't support merging relocation sections, then sorting. Instead we need to use a single .rela.dyn section. This is done by increasing the size of rela_dyn_ during do_relax to account for needed dynamic relocations, delaying adding the actual relocations until the end of relaxation once the layout has stabilised. * powerpc.cc (Target_powerpc): Add rela_dyn_size_; (update_current_size): New function. (Target_powerpc::do_relax): Capture the size of rela_dyn_ at the start of relaxation. Artifically increase its size during relaxation to account for needed indirect branches, and add those relocations at the end. (Output_data_brlt_powerpc::rel_, reset_brlt_sizes), (finalize_brlt_sizes, add_reloc, set_current_size): Delete. (Target_powerpc::make_brlt_section): Don't make reloc section.
2023-06-23[GOLD] Support setting DT_RELACOUNT lateAlan Modra11-16/+38
PowerPC gold adds relative dynamic relocs in do_relax. These aren't accounted for in the value set in add_target_dynamic_tags, which is called before do_relax. Provide a way of setting DT_RELCOUNT and DT_RELACOUNT at the point where .dynamic is written. * layout.cc (Layout::add_target_dynamic_tags): Add custom_relcount parameter. Emit DT_RELCOUNT/RELACOUNT as a custom target handled dynamic tag if set. * layout.h(Layout::add_target_dynamic_tags): Update prototype. * aarch64.cc (Target_aarch64::do_finalize_sections): Adjust add_target_dynamic_tags call. * arm.cc (Target_arm::do_finalize_sections): Likewise. * i386.cc (Target_i386::do_finalize_sections): Likewise. * mips.cc (Target_mips::do_finalize_sections): Likewise. * s390.cc (Target_s390::do_finalize_sections): Likewise. * sparc.cc (Target_sparc::do_finalize_sections): Likewise. * tilegx.cc (Target_tilegx::do_finalize_sections): Likewise. * x86_64.cc (Target_x86_64::do_finalize_sections): Likewise. * powerpc.cc (Target_powerpc::do_finalize_sections): Likewise.

2023-06-23[GOLD] powerpc DT_RELACOUNTAlan Modra1-2/+7
DT_RELACOUNT was calculated incorrectly, and relative relocs not sorted as they should be to the start of .rela.dyn, due to adding one particular class of dynamic reloc using the wrong "add" method. * powerpc.cc (Target_powerpc::Scan::global): Add relative dyn relocs for ADDR64 and similar using add_global_relative.
2023-06-21PR30536, ppc64el gold linker produces unusable clang-16 binaryAlan Modra1-1/+9
In commit 0961e631575b, the fix for PR30217, make_lplt_section and make_brlt_section were changed to use rela_dyn_ rather than their own separate dynamic reloc sections. This fails miserably whenever brlt_ is needed for long branches, due to needing to iterate sizing and thus reset brlt_ sizes.

2023-03-16PR30217, dynamic relocations using local dynamic symbolsAlan Modra1-24/+39
glibc's ld.so ignores local dynamic symbols. It's been that way forever. We therefore can't use them on dynamic relocations. Fixing that problem uncovered another problem in sorting of dynamic relocs, caused no doubt by copying make_iplt_section (where we don't want reloc sorting by the generic gold function, we want iplt relocs last) to make_lplt_section (where we do want sorting). PR 30217 * powerpc.cc (branch_needs_plt_entry): New function. (Target_powerpc::plt_off): Use it here..

Some components of GNU Binutils will pass "-Wstack-usage=262144" when "GCC >= 5.0" is detected. However, Clang does not support "-Wstack-usage", despite that related configuration part in bfd/warning.m4 handles the latest Clang (15.0.0 as of this writing) as "GCC >= 5.0". The option "-Wstack-usage" was ignored when the first version of Clang is released but even this "ignoring" behavior is removed before Clang 4.0.0.

2021-12-06[GOLD] PowerPC64 inline plt sequencesAlan Modra1-64/+162
The fixes gold failures to handle inline PLT sequences properly. PowerPC gold was always turning these back into direct calls due to gsym->use_plt_offset() returning false. This is fixed for dynamic linking by correcting get_reference_flags, and for static linking by overriding use_plt_offset() in relocate(). The rest of the patch revolves around needing to create PLT entries for inline PLT calls when statically linking (for gcc -mlongcall). The lplt section handled that for local symbols, now it does globals too. * powerpc.cc (Target_powerpc::plt_off): Return proper section for static link. (Target_powerpc::symval_for_branch): Make public. (Target_powerpc::make_lplt_section): Add Symbol_table* param. Adjust all calls. (Target_powerpc::make_local_plt_entry): Likewise. (Target_powerpc::make_local_plt_entry): New variant for global syms. (Powerpc_relobj::do_relocate_sections): Don't write lplt contents. (Output_data_plt_powerpc::do_write): Write lplt contents here. (Output_data_plt_powerpc::Output_data_plt_powerpc): Save symbol table pointer. Adjust all uses. (Output_data_plt_powerpc::add_entry): Add stash parameter. Don't do dynamic reloc handling when no reloc section. Save symbol for local plt entries. (Output_data_plt_powerpc::add_local_entry): Save symbol. (Output_data_plt_powerpc::Local_plt_ent): New class. (Output_data_plt_powerpc::sym_ents_): New vector. (Target_powerpc::Scan::get_reference_flags): Return FUNCTION_CALL|RELATIVE_REF for inline plt relocs. (Target_powerpc::Scan::global): Make entries in lplt for inline plt call relocation symbols. (Target_powerpc::Relocate::relocate): Rename has_plt_offset to use_plt_offset. Set use_plt_offset for inline plt relocs.
