2020-06-06Rename PowerPC64 pcrel GOT TLS relocationsAlan Modra2-45/+49

2019-11-19[GOLD] OSABI not set when STT_GNU_IFUNC or STB_GNU_UNIQUE symbols outputAlan Modra4-4/+52
This patch arranges to have OSABI set to ELFOSABI_GNU (if not set to some other non-zero value) when gold outputs an ifunc local or global symbol, or a unique global symbol to either .dynsym or .symtab. STT_GNU_IFUNC and STB_GNU_UNIQUE have values in the LOOS to HIOS range and therefore require interpretation according to OSABI. I'm not sure why parameters->target() is const Target& while parameters->sized_target() is Sized_target*, but it's inconvenient to use the latter in Symbol_table::finalize. So this patch adds another const_cast complained about in layout.cc and gold.cc.

2019-07-13[GOLD] PowerPC notoc eh_frameAlan Modra6-117/+190
When generating notoc call and branch stubs without the benefit of pc-relative insns, the stubs need to use LR to access the run time PC. All LR changes must be described in .eh_frame if we're to support unwinding through asynchronous exceptions. That's what this patch does. The patch has gone through way too many iterations. At first I attempted to add multiple FDEs, one for each stub. That ran into difficulties with do_plt_fde_location which is only capable of setting the address of a single FDE per Output_data section, and with removing any FDEs added on a previous do_relax pass. Removing FDEs (git commit be897fb774) went overboard in matching the FDE contents. That means either stashing the contents created for add_eh_frame_for_plt to use when calling remove_eh_frame_for_plt, or recreating contents on the fly (*) just to remove FDEs. In fact, FDE content matching is quite unnecesary. FDEs added by a previous do_relax pass are those with u_.from_linker.post_map set. So they can easily be recognised just by looking at that flag. This patch keeps that part of the multiple FDE changes. In the end I went for just one FDE per stub group to describe the call stubs. That's reasonably efficient for the common case of only needing to describe the __tls_get_addr_opt call stub. We don't expect to be making many calls using notoc stubs without pc-relative insns. *) Which has it's own set of problems. The contents must be recreated using the old stub layout, but .eh_frame size can affect stub requirements so you need to temporarily keep the old .eh_frame size when creating new stubs, then reset .eh_frame size before adding new FDEs. * ehframe.cc (Fde::operator==): Delete.

2019-07-13[GOLD] PowerPC64 ELFv2 notoc supportAlan Modra2-261/+746
Calls from notoc functions via the PLT need different stubs. Even calls to local functions requiring a valid toc pointer must go via a stub. This patch provides the support in gold. elfcpp/ * powerpc.h (R_PPC64_PLTSEQ_NOTOC, R_PPC64_PLTCALL_NOTOC): Define. gold/ * powerpc.cc (Target_powerpc::maybe_skip_tls_get_addr_call): Handle notoc calls. (is_branch_reloc): Template on size. Return true for REL24_NOTOC. Update all callers. (max_branch_delta): Likewise. (Target_powerpc::Branch_info::make_stub): Add a stub for notoc calls to functions needing a valid toc pointer. (Target_powerpc::do_relax): Layout stubs again if any need resize. (add_12_11_12, addi_12_11, addis_12_11, ldx_12_11_12, ori_12_12_0), (oris_12_12_0, sldi_12_12_32): Define. (Stub_table::Plt_stub_ent): Add notoc_ and iter_ fields. (Stub_table::Branch_stub_key, Branch_stub_key_hash): Rename from Branch_stub_ent and Branch_stub_ent hash. Remove save_res_ from key. (Stub_table::Branch_stub_ent): New struct. (class Stub_table): Add need_resize and resizing vars. (Stub_table::need_resize, branch_size): New accessors. (Stub_table::set_resizing): New function. (Stub_table::add_plt_call_entry): Handle notoc calls and resizing on seeing such or a tocsave stubs after a normal stub using the same sym. (Stub_table::add_long_branch_entry): Similarly. (Stub_table::find_long_branch_entry): Return a Branch_stub_ent*. (Stub_table::define_stub_syms): Adjust (Stub_table::build_tls_opt_head, build_tls_opt_tail): New functions. (build_notoc_offset): New function. (Stub_table::plt_call_size): Move out of line. Handle notoc calls. (Stub_table::branch_stub_size): Similarly. (Stub_table::do_write): Separate loop for ELFv2 stubs, handling notoc calls. Simplify ELFv1 loop. Output notoc branch stubs. Use build_tls_opt_head and build_tls_opt_tail. (Target_powerpc::Scan::get_reference_flags): Handle REL24_NOTOC. (Target_powerpc::Scan::reloc_needs_plt_for_ifunc): Likewise, and PLTSEQ_NOTOC and PLTCALL_NOTOC. (Target_powerpc::Scan::local, global, relocate): Likewise.
2019-06-28[GOLD] PowerPC tweak relnum testsAlan Modra2-2/+7
There is a call of relocate() to perform a single relocation. In that case the "relnum" parameter is -1U and of course it isn't appropriate to consider any of the PowerPC code sequence optimisations triggered by a following relocation. * powerpc.cc (Target_powerpc::Relocate::relocate): Don't look at next/previous reloc when relnum is -1.
2019-06-28[GOLD] PowerPC linkage table errorAlan Modra2-5/+25
This fixes a segfault when attempring to output a "linkage table error". "object" is only non-NULL in the local symbol case. * powerpc.cc (Stub_table::plt_error): New function. (Stub_table::do_write): Use it. (Output_data_glink::do_write): Don't segfault emitting linkage table error.
2019-06-28[GOLD] R_PPC64_REL16_HIGH relocsAlan Modra2-0/+38
These relocs have been around for quite a while. It's past time gold supported them. elfcpp/ * powerpc.h (R_PPC64_REL16_HIGH, R_PPC64_REL16_HIGHA), (R_PPC64_REL16_HIGHER, R_PPC64_REL16_HIGHERA), (R_PPC64_REL16_HIGHEST, R_PPC64_REL16_HIGHESTA): Define. gold/ * powerpc.cc (Target_powerpc::Scan::get_reference_flags): Handle REL16_HIGH* relocs. (Target_powerpc::Scan::local): Likewise. (Target_powerpc::Scan::global): Likewise. (Target_powerpc::Relocate::relocate): Likewise.

2019-05-11Fix problem with ICF where diffs in EH frame info is ignored.Joshua Oreman9-34/+438
PR gold/21066 * gc.h (gc_process_relocs): Track relocations in .eh_frame sections when ICF is enabled, even though the .eh_frame sections themselves are not foldable. * icf.cc (get_section_contents): Change arguments to permit operation on just part of a section. Include extra identity regions in the referring section's contents recursively. (match_sections): Lock object here instead of in get_section_contents so that get_section_contents can operate recursively. (Icf::add_ehframe_links): New method. (Icf::find_identical_sections): Pass .eh_frame sections to add_ehframe_links(). Increase default iteration count from 2 to 3 because handling exception info typically requires one extra iteration. * icf.h (Icf::extra_identity_list_): New data member with accessor. (is_section_foldable_candidate): Include .gcc_except_table sections. * options.h: Update documentation for new default ICF iteration count. * testsuite/Makefile.am (icf_test_pr21066): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/icf_test_pr21066.cc: New source file. * testsuite/icf_test_pr21066.sh: New test script.
