Update year range in copyright notice of binutils files
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently. |

Update year range in copyright notice of binutils files
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match. |

Update year range in copyright notice of binutils files
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files. |

IFUNC: Update IFUNC resolver check with DT_TEXTREL
Add ifunc_resolvers to elf_link_hash_table and use it for both x86 and ppc64. Before glibc commit b5c45e837, DT_TEXTREL is incompatible with IFUNC resolvers.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete. (bfd_section_name, bfd_section_size, bfd_section_vma), (bfd_section_lma, bfd_section_alignment): Lose bfd parameter. (bfd_section_flags, bfd_section_userdata): New.

x86; Allow IFUNC pointer defined in PDE
If IFUNC symbol is defined in position-dependent executable, we should change it to the normal function and set its address to its PLT entry which should be resolved by R_*_IRELATIVE at run-time.

Don't generate PLT for IFUNC GOT/pointer reference
If a backend supports it, PLT entry isn't needed when all references to a STT_GNU_IFUNC symbols are done via GOT or static function pointers. For GOT entries, We generate dynamic R_*_GLOB_DAT relocations for preemptable symbols and R_*_IRELATIVE relocations for non-preemptable symbols to update them with real function address. For static pointer pointers, we generate dynamic pointer relocations and store them in: 1. .rel[a].ifunc section in PIC object. 2. .rel[a].got section in dynamic executable. 3. .rel[a].iplt section in static executable. We don't allocate GOT entry if it isn't used. bfd/ PR ld/20253 * elf-bfd.h (_bfd_elf_allocate_ifunc_dyn_relocs): Add an bfd_boolean argument. * elf-ifunc.c (_bfd_elf_create_ifunc_sections): Replace "shared object" with "PIC object" in comments.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add _bfd_elf_ifunc_get_synthetic_symtab
In i386 and x86-64 binaries with ifunc, relocations against .got.plt section may not be in the same order as entries in PLT section. This patch adds _bfd_elf_ifunc_get_synthetic_symtab. It takes a function pointer which returns an array of PLT entry symbol values. It calls the function pointer to get the PLT entry symbol value array indexed by relocation index, instead of calling plt_sym_val on each relocation index.

Check regular reference without non-GOT reference
non_got_ref may not be set when building shared library. We need to set
non_got_ref if there are any non-PIC relocations. But we only did this
when there were no PLT/GOT relocations. It failed when there is a PLT
relocation. This checkin moves the non_got_ref check out.
