2014-03-05Support R_PPC64_ADDR64_LOCALAlan Modra1-0/+38
This adds support for "func@localentry", an expression that returns the ELFv2 local entry point address of function "func". I've excluded dynamic relocation support because that obviously would require glibc changes. include/elf/ * ppc64.h (R_PPC64_REL24_NOTOC, R_PPC64_ADDR64_LOCAL): Define. bfd/ * elf64-ppc.c (ppc64_elf_howto_raw): Add R_PPC64_ADDR64_LOCAL entry. (ppc64_elf_reloc_type_lookup): Support R_PPC64_ADDR64_LOCAL. (ppc64_elf_check_relocs): Likewise. (ppc64_elf_relocate_section): Likewise. * Add BFD_RELOC_PPC64_ADDR64_LOCAL. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. gas/ * config/tc-ppc.c (ppc_elf_suffix): Support @localentry.

(Target_powerpc::Relocate::relocate): Likewise.
2014-02-19Control powerpc64-ld provision of register save/restoreAlan Modra1-1/+1
This patch allows the user to override powerpc64-ld's default for providing linker generated register save and restore functions as used by gcc -Os code. Normally these are not provided by ld -r, so Linux kernel modules have needed to include their own copies. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Add save_restore_funcs. * elf64-ppc.c (ppc64_elf_func_desc_adjust): Use it to control provision of out-of-line register save/restore routines. ld/ * emultempl/ppc64elf.em (params): Init new field. (ppc_create_output_section_statements): Set params.save_restore_funcs default. (PARSE_AND_LIST_*): Add support for --save-restore-funcs and --no-save-restore-funcs.
2014-02-17Consolidate ppc64 ld/bfd communicationAlan Modra1-125/+100
Moves assorted variables used to communicate between ld and bfd into a struct, hooks it into the bfd link_hash_table early, and removes all other places where such variables were passed piecemeal. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Define. (ppc64_elf_init_stub_bfd, ppc64_elf_edit_opd, ppc64_elf_tls_setup, ppc64_elf_setup_section_lists, ppc64_elf_size_stubs, ppc64_elf_build_stubs): Update prototype. * elf64-ppp.c (struct ppc_link_hash_table): Add params, delete other fields now in params. Adjust code throughout file. (ppc64_elf_init_stub_bfd): Delete "abfd" parameter, add "params". Save params pointer in htab. (ppc64_elf_edit_opd, ppc64_elf_tls_setup, ppc64_elf_setup_section_lists, ppc64_elf_size_stubs, ppc64_elf_build_stubs): Remove parameters now in "params". ld/ * emultemps/ppc64elf.em (params): New static struct replacing various other static vars. Adjust code throughout file.

2014-01-24Fixes powerpc64le ld segfaults when --emit-relocs is used.Alan Modra1-4/+5
ELFv2 needs fewer relocs to annotate plt call stubs. I correctly allocated a smaller buffer and wrote the proper relocs, but stupidly bumped the reloc count as for ELFv1. * elf64-ppc.c (ppc_build_one_stub): Correct reloc count passed to get_relocs for ELFv2.

2013-12-03More PowerPC64 ELFv2 --just-symbols fixesAlan Modra1-15/+15
I don't know what I was thinking here to omit the save of r2. Possibly I was looking at -msave-toc-indirect code at the time, where r2 is saved in the function prologue. * elf64-ppc.c (ppc_build_one_stub <ppc_stub_plt_branch_r2off>): Don't omit saving of r2 for ELFv2. Don't addi 2,2,0. (ppc_size_one_stub <ppc_stub_plt_branch_r2off>): Adjust to suit.
2013-12-03PowerPC64 linking of --just-symbols objects (klibc)Alan Modra1-4/+2
With -mcmodel=medium we can't assume that a -R object doesn't use toc-relative addressing if there's no toc. Lots of things are accessed via r2, not just the toc/got section. Also, testing for .opd is plain wrong for ELFv2. * elf64-ppc.c (ppc64_elf_link_just_syms): Remove .got check. Handle ELFv2.
2013-11-11PowerPC64 ELFv2, allocate dynreloc space for ifuncAlan Modra1-2/+1

2013-11-11Correct elf64-ppc.c handling of protected symbolsAlan Modra1-14/+10
Some places in elf64-ppc.c carelessly used SYMBOL_CALLS_LOCAL when the proper test is SYMBOL_REFERENCES_LOCAL for cases where we take the address of a protected symbol. This works OK for function descriptors but not for ELFv2. Setting symbols to their global entry stub a little earlier is to ensure _bfd_elf_hash_symbol allows such symbols in .gnu.hash. * elf64-ppc.c (ppc64_elf_edit_toc): Use SYMBOL_REFERENCES_LOCAL here, not SYMBOL_CALLS_LOCAL. (ppc64_elf_relocate_section): Likewise. (size_global_entry_stubs): Set undefined symbols on their global entry stubs here.. (build_global_entry_stubs): ..rather than here. (ppc64_elf_build_stubs): Don't reset glink->size before calling build_global_entry_stubs.

2013-11-05Hide ppc64 .TOC. from --export-dynamicAlan Modra1-3/+12
I can't see any good reason why anyone would want a dynamic .TOC., so hide it in a way that is respected by _bfd_elf_export_symbol.

2013-11-04PowerPC64 ELFv2 symbols defined in pltAlan Modra1-48/+251
In a non-pic executable, ELFv2 like other targets, needs to emit a plt entry even for non-call references to functions defined in shared libraries, and define the function on the plt code. * elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Copy pointer_equality_needed flag.

2013-11-02Simplify ppc64 code setting toc_off.Alan Modra1-35/+18
Every function has a nominal toc pointer value, even if it isn't used, so set toc_off for every code section to the value used in that object file. The thinking here was that if a code section didn't use the toc it could use the previous object file's toc pointer value. It can, but doing so is only a gain if functions in that section are called mostly from previous objects sharing the same toc. We lose if the functions in question are called mostly from the current object or following objects, and it's a good bet they will probably mostly be called from the current object. * elf64-ppc.c (ppc64_elf_next_input_section): Always set toc_off to value for object file.
2013-10-30Replace DT_PPC_TLSOPT with DT_PPC_OPT.Alan Modra1-5/+15
This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality and more. This isn't backwards compatible, but the TLSOPT tag hasn't been used since the tls optimisation support was never submitted to glibc. /include/elf/ * ppc.h (DT_PPC_TLSOPT): Delete. (DT_PPC_OPT, PPC_OPT_TLS): Define. * ppc64.h (DT_PPC64_TLSOPT): Delete.

2013-10-30ELFv2 stub, plt and glink changesAlan Modra1-119/+207
An ELFv2 PLT entry is simply the address of the target function rather than three (or two) words to specify entry, toc and static chain. PLT call stubs are correspondingly simpler and need no thread safety barrier. The glink resolver stub and branch table also is simplified, a change that could be applied to ELFv1 too, but isn't as yet. * elf64-ppc.c (PLT_ENTRY_SIZE, PLT_INITIAL_ENTRY_SIZE): Add htab parameter and adjust for ELFv2.

2013-10-30Report overflow on PowerPC64 @h and @ha relocations.Alan Modra1-32/+151
This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.
