Emit a warning when -z relro is unsupported
ld silently accepts -z relro and -z norelro for targets that lack the
necessary GNU_RELRO support. This patch makes those targets emit a
warning instead, and adds testsuite infrastructure to detect when
relro is unsupported.

* testsuite/lib/binutils-common.exp (check_relro_support): New proc.
(run_dump_test): Use check_relro_support to decide whether to pass
extra ld option "-z norelro".

-z relro and -z norelro when target support for GNU_RELRO is lacking.

AArch64: Set the correct ELF class for AArch64 stubs (PR/25210)
This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs.
After doing this the stub section starts behaving like a normal object file
loaded from disk. That is SEC_LINKER_CREATED causes us to have to write the
section manually.
This flag was added as a fix for PR 24753. I believe that
fix to still be correct as linker created sections don't have a size on disk
and it fixes the Arm bootstrap regression. But in this case specifying the
correct section class also makes the stub section not be considered by
compress.c.
So I'm partially revert this change so that we don't have to manage the section
manually as implied by SEC_LINKER_CREATED.

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.

Move elf32.em and elf-generic.em functions
Many ELF linker targets support multiple "emulations" and thus have
multiple copies of elf32.em being compiled and linked into ld. This

AArch64: Implement choice between Cortex-A53 erratum workarounds. (PR ld/24373)
The Cortex-A53 erratum currently has two ways it can resolve the erratum when
using the flag --fix-cortex-a53-843419:
1) If the address is within the range of an ADR instruction it rewrites the ADRP
into an ADR, and those doesn't need the use of a veneer.
2) If the address is not within range, it adds a branch to a veneer which will
execute the final bit of the erratum workaround and branch back to the call
site.
When we do this we always generate the veneers and we always align the size of
the text section to 4KB. This is because we only know which workaround we can
use after all linking has finished and all addresses are known. This means even
though the veneers are not used, we still generate the section and we still
change the size of the input section.
This is problematic for small memory devices as this would require the user to
take about a ~4KB hit in memory even though it's not even used.
Since there's no real way to restart the linking process from the final write
phase this patch solves the issue by allowing the user more control over which
erratum workaround gets used.
Concretely this changes the option --fix-cortex-a53-843419 to take optional
arguments --fix-cortex-a53-843419[=full|adr|adrp]
- full (default): Use both ADRP and ADR workaround. This is equivalent to not
specifying any options and is the default behavior before this
patch.
- adr: Only use the ADR workaround, this will not cause any increase in binary
size but linking will fail if the referenced address is out of range of
an ADR instruction.
- adrp: Use only the ADRP workaround, this will never rewrite your ADRP.
In the cases where the user knows how big their binaries are the `adr` option
would prevent the unneeded overhead.

This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds new definitions of PAC enabled PLTs and both BTI and PAC enabled PLTs. 2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT for the PAC enabled PLTs. 3) This patch adds a new ld command line option: --pac-plt. In the presence of this option, the linker uses the PAC enabled PLTs and marks with DT_AARCH64_PAC_PLT. 4) In case both BTI and PAC are enabled the linker should pick PLTs enabled with both and also use dynamic tags for both.

[BFD, LD, AArch64, 2/3] Add --force-bti to enable BTI and to select BTI enabled PLTs
This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds a new ld command line option: --force-bti. In the presence of this option, the linker enables BTI with the GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning in case of missing gnu notes for BTI in inputs. 2) It also defines a new set of BTI enabled PLTs. These are used either when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI or when the new --force-bti option is used. This required adding new fields in elf_aarch64_link_hash_table so that we could make the PLT related information more generic. 3) It also defines a dynamic tag DT_AARCH64_BTI_PLT. The linker uses this whenever it picks BTI enabled PLTs.

ld error/warning messages
This patch standardizes messages in ld, to better conform to the GNU coding standard. Besides issues of capitalization and full-stops, I've - Split up help messages for target options, so that adding a new option does not mean loss of translation for all the others. - Embedded tabs have been removed, since a user might have tab stops set at other than 8 char intervals. - Added missing program name (%P). ld isn't the compiler. - Put %F and %X first (and removed %X if %F was present). These can go anywhere, but look silly in the m%Fiddle of a message, and choosing "%P%F:" in some messages but "%F%P:" in others leads to the likelihood of duplication in ld.pot. Besides, the colon belongs with %P. * emulparams/call_nop.sh, * emulparams/cet.sh, * emulparams/elf32mcore.sh, * emultempl/aarch64elf.em * emultempl/aix.em, * emultempl/alphaelf.em, * emultempl/armcoff.em, * emultempl/armelf.em, * emultempl/avrelf.em, * emultempl/beos.em, * emultempl/bfin.em, * emultempl/cr16elf.em, * emultempl/elf32.em, * emultempl/elf-generic.em, * emultempl/hppaelf.em, * emultempl/linux.em, * emultempl/lnk960.em, * emultempl/m68hc1xelf.em, * emultempl/m68kcoff.em, * emultempl/m68kelf.em, * emultempl/metagelf.em, * emultempl/mipself.em, * emultempl/mmix-elfnmmo.em, * emultempl/mmo.em, * emultempl/msp430.em, * emultempl/nds32elf.em, * emultempl/nios2elf.em, * emultempl/pe.em, * emultempl/pep.em, * emultempl/ppc32elf.em, * emultempl/ppc64elf.em, * emultempl/scoreelf.em, * emultempl/sh64elf.em, * emultempl/spuelf.em, * emultempl/sunos.em, * emultempl/tic6xdsbt.em, * emultempl/ticoff.em, * emultempl/v850elf.em, * emultempl/vms.em, * emultempl/vxworks.em, * emultempl/xtensaelf.em, * ldcref.c, * ldctor.c, * ldexp.c, * ldfile.c, * ldgram.y, * ldlang.c, * ldmain.c, * ldmisc.c, * ldwrite.c, * lexsup.c, * mri.c, * pe-dll.c, * plugin.c: Standardize error/warning messages. * testsuite/ld-arc/jli-overflow.err, * testsuite/ld-arm/cmse-implib-errors.out, * testsuite/ld-arm/cmse-new-earlier-later-implib.out, * testsuite/ld-arm/cmse-new-implib-not-sg-in-implib.out, * testsuite/ld-arm/cmse-new-wrong-implib.out, * testsuite/ld-arm/cmse-veneers-no-gnu_sgstubs.out, * testsuite/ld-arm/cmse-veneers-wrong-entryfct.out, * testsuite/ld-arm/vxworks1-static.d, * testsuite/ld-cris/tls-err-20x.d, * testsuite/ld-cris/tls-err-29.d, * testsuite/ld-cris/tls-err-31.d, * testsuite/ld-cris/tls-err-33.d, * testsuite/ld-cris/tls-err-35.d, * testsuite/ld-cris/tls-err-37.d, * testsuite/ld-cris/tls-err-39.d, * testsuite/ld-cris/tls-err-41.d, * testsuite/ld-cris/tls-err-43.d, * testsuite/ld-cris/tls-err-45.d, * testsuite/ld-cris/tls-err-47.d, * testsuite/ld-cris/tls-err-49.d, * testsuite/ld-cris/tls-err-51.d, * testsuite/ld-cris/tls-err-67.d, * testsuite/ld-elf/dwarf2.err, * testsuite/ld-elf/dwarf3.err, * testsuite/ld-elf/orphan-5.l, * testsuite/ld-elf/orphan-6.l, * testsuite/ld-i386/vxworks1-static.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips.d, * testsuite/ld-mips-elf/bal-jalx-pic-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic.d, * testsuite/ld-mips-elf/jal-global-overflow-1.d, * testsuite/ld-mips-elf/jal-local-overflow-1.d, * testsuite/ld-mips-elf/mode-change-error-1.d, * testsuite/ld-mips-elf/unaligned-branch-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-r6-2.d, * testsuite/ld-mips-elf/unaligned-branch.d, * testsuite/ld-mips-elf/unaligned-jalx-1.d, * testsuite/ld-mips-elf/unaligned-jalx-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jalx-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jump-micromips.d, * testsuite/ld-mips-elf/unaligned-jump-mips16.d, * testsuite/ld-mips-elf/unaligned-jump.d, * testsuite/ld-mips-elf/unaligned-ldpc-1.d, * testsuite/ld-mips-elf/unaligned-lwpc-1.d, * testsuite/ld-mips-elf/undefined.d, * testsuite/ld-mips-elf/vxworks1-static.d, * testsuite/ld-mmix/bpo-20.d, * testsuite/ld-mmix/bpo-20m.d, * testsuite/ld-mmix/bpo-7.d, * testsuite/ld-mmix/bpo-7m.d, * testsuite/ld-mmix/bpo-8.d, * testsuite/ld-mmix/bpo-8m.d, * testsuite/ld-mmix/greg-17.d, * testsuite/ld-mmix/greg-18.d, * testsuite/ld-mmix/greg-8.d, * testsuite/ld-mmix/greg-9.d, * testsuite/ld-plugin/plugin-14.d, * testsuite/ld-plugin/plugin-15.d, * testsuite/ld-plugin/plugin-16.d, * testsuite/ld-plugin/plugin-20.d, * testsuite/ld-plugin/plugin-21.d, * testsuite/ld-plugin/plugin-22.d, * testsuite/ld-plugin/plugin-23.d, * testsuite/ld-plugin/plugin-6.d, * testsuite/ld-plugin/plugin-7.d, * testsuite/ld-plugin/plugin-8.d, * testsuite/ld-powerpc/aix-weak-3-32.d, * testsuite/ld-powerpc/aix-weak-3-64.d, * testsuite/ld-powerpc/vxworks1-static.d, * testsuite/ld-sh/vxworks1-static.d, * testsuite/ld-sparc/vxworks1-static.d, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-x86-64/pie1.d: Update for changed errors and warnings. * testsuite/ld-elf/warn1.d, * testsuite/ld-elf/warn2.d: Correct regex. |

ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and
garbage collection. Since the symbol resolution is known, check_relocs
can be simplified. Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.
Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.
ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.
Tested natively without regressions on i686, x86-64 and x32. Tested
cross binutils on x86-64 without regressions for aarch64-linux,
alpha-linux, arm-linux, bfin-elf, cr16-elf, cris-elf, crx-elf, frv-linux,

[AArch64] Also puts value in place for R_AARCH64_RELATIVE
When handling absolute relocations for global symbols bind within the shared object, AArch64 will generate one dynamic RELATIVE relocation, but won't apply the value for this absolution relocations at static linking stage. This is different from AArch64 gold linker and x86-64. This is not a bug as AArch64 is RELA, there is only guarantee that relocation addend is placed in the relocation entry. But some system softwares originally writen for x86-64 might assume AArch64 bfd linker gets the same behavior as x86-64, then they could take advantage of this buy skipping those RELATIVE dynamic relocations if the load address is the same as the static linking address. This patch makes AArch64 BFD linker applies absolution relocations at static linking stage for scenario described above. Meanwhile old AArch64 android loader has a bug (PR19163) which relies on current linker behavior as a workaround, so the same option --no-apply-dynamic-relocs added. |

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.

[AArch64] Workaround for Cortex A53 erratum 843419
Some early revisions of the Cortex-A53 have an erratum (843419). The details of the erratum are quite complex and involve dynamic conditions. For the purposes of the workaround we have simplified the static conditions to an ADRP in the last two instructions of a 4KByte page, followed within four instructions by a load/store dependent on the ADRP. This patch adds support to conservatively scan for and workaround Cortex A53 erratum 843419. There are two different workaround strategies used. The first is to rewrite ADRP instructions which form part of an erratum sequence with an ADR instruction. In situations where the ADR provides insufficient offset the dependent load or store instruction from the sequence is moved to a stub section and branches are inserted from the original sequence to the relocated instruction and back again. Stub section sizes are rounded up to a multiple of 4096 in order to ensure that the act of inserting work around stubs does not create more errata sequences. Workaround stubs are always inserted into the stub section associated with the input section containing the erratum sequence. This ensures that the fully relocated form of the veneered load store instruction is available at the point in time when the stub section is written. |
