AArch64: Fix regression in Cortex A53 erratum when PIE. (PR ld/23904) The fix for PR ld/22263 causes TLS relocations using ADRP to be relaxed into MOVZ, however this causes issues for the erratum code. The erratum code scans the input sections looking for ADRP instructions and notes their location in the stream. It then later tries to find them again in order to generate the linker stubs. Due to the relaxation it instead finds a MOVZ and hard aborts. Since this relaxation is a valid one, and in which case the erratum no longer applies, it shouldn't abort but instead just continue. This changes the TLS relaxation code such that when it finds an ADRP and it relaxes it, it removes the erratum entry from the work list by changing the stub type into none so the stub is ignored. The entry is not actually removed as removal is a more expensive operation and we have already allocated the memory anyway. The clearing is done for IE->LE and GD->LE relaxations, and a testcase is added for the IE case. The GD case I believe to be impossible to get together with the erratum sequence due to the required BL which would break the sequence. However to cover all basis I have added the guard there as well. build on native hardware and regtested on aarch64-none-elf, aarch64-none-elf (32 bit host), aarch64-none-linux-gnu, aarch64-none-linux-gnu (32 bit host) Cross-compiled and regtested on aarch64-none-linux-gnu, aarch64_be-none-linux-gnu Testcase in PR23940 tested and works as expected now and benchmarks ran on A53 showing no regressions and no issues. bfd/ChangeLog: PR ld/23904 * elfnn-aarch64.c (_bfd_aarch64_adrp_p): Use existing constants.

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. bfd/ChangeLog: PR ld/24373 * bfd-in.h (enum erratum_84319_opts): New (bfd_elf64_aarch64_set_options, bfd_elf32_aarch64_set_options): Change int to enum erratum_84319_opts. * bfd-in2.h: Regenerate. * elfnn-aarch64.c (struct elf_aarch64_link_hash_table): Change fix_erratum_843419 to use new enum, remove fix_erratum_843419_adr.

[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.

[AArch64] Allow COPY relocation elimination As discussed at the PR, this patch tries to avoid COPY relocation generation and propagate the original relocation into runtime if it was relocating on writable section. The ELIMINATE_COPY_RELOCS has been set to true and it's underlying infrastructure has been improved so that the COPY reloc elimination at least working on absoluate relocations (ABS64) on AArch64. BFD linker copy relocation elimination framwork requires the backend to always allocate dynrelocs for all those relocation types that are possible to introduce copy relocations. This is for adjust_dynamic_symbol hook to be able to get all symbol reference information. Should one symbol is referenced by more than one relocations, if there is any of them needs copy relocation then linker should generate it. bfd/ PR ld/21532 * elfnn-aarch64.c (ELIMINATE_COPY_RELOCS): Set to 1.

[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.

[BFD, AArch64, x86] Improve warning for --force-bti The AArch64 linker option to turn on BTI (--force-bti) warns in case there are input objects which have a missing GNU NOTE section for BTI. This patch is trying to improve the warnings that come out. In order to do so, I propose adding a new argument to elf_merge_gnu_properties and the backend function merge_gnu_properties. This new argument makes sure that we now pass both the objects along with the properties to which they belong to. The x86 backend function has also been updated to match this change. *** bfd/ChangeLog *** 2019-03-21 Sudakshina Das <sudi.das@arm.com> * elf-bfd.h (struct elf_backend_data): Add argument to merge_gnu_properties. * elf-properties.c (elf_merge_gnu_properties): Add argument to itself and while calling bed->merge_gnu_properties.

AArch64: Fix LD crash on weak and undefined TLS symbols. (PR/24602). This patch fixes a few linker crashes due to TLS code reaching an assert when it shouldn't. The first scenario is with weak TLS symbols that remain weak during linking. In this case the mid-end would not have seen a TLS symbol and so wouldn't have allocated the TLS section. We currently assert here and the linker crashes with a not very useful message. This patch changes this to return the value 0 for the TLS symbol in question emulating what lld and gold and other BFD targets do. However because weak TLS is implementation defined and we don't define any behavior for it I also emit a warning to the user to inform them of such. Secondly when a strong TLS reference is undefined. The linker crashes even after it correctly reported that there is an undefined reference. This changes it so that it gracefully exits and reports a useful error. bfd/ChangeLog: PR ld/24601 * elfnn-aarch64.c (aarch64_relocate): Handle weak TLS and undefined TLS.
