2022-06-27drop XC16x bitsJan Beulich3-24/+0
Commit 04f096fb9e25 ("Move the xc16x target to the obsolete list") moved the architecture from the "obsolete but still available" to the "obsolete / support removed" list in config.bfd, making the architecture impossible to enable (except maybe via "enable everything" options"). Note that I didn't touch */po/*.po{,t} on the assumption that these would be updated by some (half)automatic means.
2022-06-27PowerPC64 .branch_lt addressAlan Modra1-1/+1
.branch_lt is really an extension of .plt, as is .iplt. We'd like all of the PLT sections to be fixed relative to .TOC. after stub sizing, because changes in offset to PLT entries might mean a change in stub sizes. When -z relro, the relro layout does this by laying out sections from the end of the relro segment. So for example, a change in .eh_frame (which happens after stub sizing) will keep the same GOT to PLT offset when -z relro. Not so when -z norelro, because then the usual forward layout of section is done and .got is more aligned than .branch_lt. * emulparams/elf64ppc.sh: Set .branch_lt address fixed relative to .got. * testsuite/ld-powerpc/elfv2exe.d: Adjust to suit.

2022-01-18PowerPC64 DT_RELRAlan Modra1-0/+1
PowerPC64 takes a more traditional approach to DT_RELR than x86. Count relative relocs in check_relocs, allocate space for them and output in the usual places but not doing so when enable_dt_relr. DT_RELR is sized in the existing ppc stub relaxation machinery, run via the linker's ldemul_after_allocation hook. DT_RELR is output in the same function that writes ppc stubs, run via ldemul_finish. This support should be considered experimental. bfd/ * elf64-ppc.c (struct ppc_local_dyn_relocs): Renamed from ppc_dyn_relocs. Add rel_count field. Update uses. (struct ppc_dyn_relocs): New.

2022-01-12ld: Initial DT_RELR supportH.J. Lu4-0/+21
Add a -z pack-relative-relocs option to enable DT_RELR and create a relr.dyn section for DT_RELR. DT_RELR is implemented with the linker relaxation infrastructure, but it doesn't require the --relax option enabled. -z pack-relative-relocs implies -z combreloc. -z nocombreloc implies -z nopack-relative-relocs. -z pack-relative-relocs is chosen over the similar option in lld, --pack-dyn-relocs=relr, to implement a glibc binary lockout mechanism with a special glibc version symbol, to avoid random crashes of DT_RELR binaries with the existing glibc binaries. bfd/ * elf-bfd.h (elf_link_hash_table): Add srelrdyn. * elflink.c (_bfd_elf_link_create_dynamic_sections): Create a .relr.dyn section for DT_RELR. include/ * bfdlink.h (bfd_link_info): Add enable_dt_relr. ld/ * News: Mention -z pack-relative-relocs and -z nopack-relative-relocs. * ld.texi: Document -z pack-relative-relocs and -z nopack-relative-relocs. * ldelf.c (ldelf_after_parse): Disable DT_RELR if not building PIE nor shared library.

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.

2020-11-27ELF: Support .noinit and .persistent sectionsJozef Lawrynowicz1-13/+5
The ".persistent" section is for data that should be initialized during load, but not during application reset. The ".noinit" section is for data that should not be initialized during load or application reset. Targets utilizing the elf.sc linker script template can define HAVE_{NOINIT,PERSISTENT}=yes to include the .noinit or .persistent output sections in the generated linker script. Targets with existing support for .noinit did not handle unique .noinit.* and .gnu.linkonce.n.* sections the .noinit output section, this patch also fixes that. bfd/ChangeLog: * elf.c (special_sections_g): Add .gnu.linkonce.n and .gnu.linkonce.p.

2020-10-16RISC-V: Support GNU indirect functions.Nelson Chu1-0/+1
Generally, glibc dynamic linker should have two ways to deal with ifunc - one is to handle the IRELATIVE relocations for the non-preemtive ifunc symbols, the other is to handle the R_RISCV_32/64 and R_RISCV_JUMP_SLOT relocations with the STT_IFUNC preemtive symbols. No matter which method is used, both of them should get the resolved ifunc symbols at runtime. Therefore, linker needs to generate the correct dynamic relocations for ifunc to make sure the the dynamic linker works well. For now, there are thirteen relocations are supported for ifunc in GNU ld, * R_RISCV_CALL and R_RISCV_CALL_PLT: The RISC-V compiler won't generate R_RISCV_JAL directly to jump to an ifunc. Besides, we disable the relaxations for the relocation referenced to ifunc, so just handling the R_RISCV_CALL and R_RISCV_CALL_PLT should be enough. Linker should generate a .plt entry and a .got.plt entry for it, and also needs to insert a dynamic IRELATIVE in the .got.plt enrty, or insert a R_RISCV_JUMP_SLOT when generating shared library. * R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO12_I/S: LA/LLA pattern with local fPIC ifunc symbol, or any non-PIC ifunc symbol. The PC-relative relocation. The current linker will deal with them in the same way as R_RISCV_CALL_PLT. * R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO12_I/S: LA pattern with global PIC ifunc symbol. Linker should insert a dynamic IRELATIVE in the .got entry, or insert a R_RISCV_32/64 when generating shared library. * R_RISCV_32 and R_RISCV_64: Store the ifunc symbol into the data section. Linker should insert a dynamic IRELATIVE in the data section, or insert a R_RISCV_32/64 when generating shared library. * R_RISCV_HI20 and R_RISCV_LO12_I/S: The LUI + ADDI/LW/SW patterns. The absolute access relocation. The medlow model without the -fPIC compiler option should generate them. The ld ifunc testsuites "Build pr23169a" and "Build pr23169d" need the relocations, they are in the ld/testsuite/ld-ifunc/, and need compiler support. However, we also made some optimizations with reference to x86, * If GOT and PLT relocations refer to the same ifunc symbol when generating pie, then they can actually share a .got entry without creating two entries to store the same value and relocation. * If GOT, PLT and DATA relocations refer to the same ifunc symbol when generating position dependency executable, then linker will fill the address of .plt entry into the corresponding .got entry and data section, without insert any dynamic relocations for the GOT and DATA relocations. For the ifunc testcases, there are three types of them, 1. ifunc-reloc-*: Only check the single type of relocation refers to ifunc symbol. * ifunc-reloc-call: R_RISCV_CALL and R_RISCV_CALL_PLT. * ifunc-reloc-data: R_RISCV_32 and R_RISCV_64. * ifunc-reloc-got: R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO_I/S. * ifunc-reloc-pcrel: R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO_I/S. 2. ifunc-[nonplt|plt]-*: If we don't have PLT relocs, then don't need to create the PLT and it's .plt entries. * ifunc-nonplt: Combine R_RISCV_GOT_HI20 and R_RISCV_32/64. * ifunc-plt: Combine all ifunc relocations. 3. ifunc-seperate-*: If we link the ifunc caller and resolver into the same module (link the objects), then the results are the same as the ifunc-reloc-* and ifunc-[noplt|plt]-* testcases. Consider the cases that the ifunc callers and resolver are in the different modules, that is, we compile the ifunc resolver to the shared library first, and then link it with the ifunc callers. The output of ifunc callers should be the same as the normal STT_FUNC cases, and the shared ifunc resolver should define the symbols as STT_IFUNC. The R_RISCV_PCREL_HI20 reloc is special. It should be linked and resolved locally, so if the ifunc resolver is defined in other modules (other shared libraries), then the R_RISCV_PCREL_HI20 is unresolvable, and linker should issue an unresolvable reloc error. bfd/ * elfnn-riscv.c: Include "objalloc.h" since we need objalloc_alloc.

2020-10-09x86: Support GNU_PROPERTY_X86_ISA_1_V[234] markerH.J. Lu4-0/+21
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA levels: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250 Update GNU_PROPERTY_X86_ISA_1_XXX macros: https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13 in x86 ELF binaries to indicate that micro-architecture ISA levels required to execute the binary: #define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2) #define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2) #define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0) #define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1) #define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2) The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX. In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2 directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4 instructions. Add -z x86-64-v[234] linker command line option to mark x86-64-v[234] ISA level as needed. Also add #define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11) for mask registers. bfd/ PR gas/26703 * elf-linker-x86.h (elf_linker_x86_params): Add isa_level. * elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Merge GNU_PROPERTY_X86_ISA_1_V[234].

2020-07-19ld: optionally emit _etext last, before .dataHans-Peter Nilsson1-0/+4
So, here's my suggestion for making _init .. __etext cover .text + .rodata (including things like the read-only exception tables) for elf64mmix. A quick web search gives that __etext (and friends) isn't well defined, so each target can interpret the "end of text segment" to their own liking. It seems likely this change is also a better fit than the default for other ports, at least those with .rodata after .text in the same segment. The presence of a separate rodata-segment is optional (and not true for elf64mmix). This is reflected in the name as SEPARATE_TEXT / SEPARATE_CODE isn't considered, to keep it simple; each target has to make sure their settings of variables make sense. ld: * scripttempl/elf.sc (ETEXT_LAST_IN_RODATA_SEGMENT): New variable. * emulparams/elf64mmix.sh (ETEXT_LAST_IN_RODATA_SEGMENT): Define. * testsuite/ld-mmix/sec-1.d: Adjust.

2019-11-07Remove CR16C supportAlan Modra1-5/+0
I think it is past time to remove CR16C support. CR16C was added in 2004, and only for ld. gas and binutils support is lacking, and there have been no commits to bfd/elf32-cr16c.c other than warning fixes or global maintainers making changes to all targets. I see no maintainer listed for CR16C, and no commits from anyone at NSC supporting the target. Furthermore, at the time the CR16 support was added in 2007, config.sub was changed upstream to no longer recognise cr16c as a valid cpu. That means the CR16C ld support is only available as a secondary target by configuring with, for example, --enable-targets=all or --enable-targets=cr16c-unknown-elf. No testing of the CR16C target is possible. include/ * elf/cr16c.h: Delete. bfd/ * cpu-cr16c.c: Delete. * elf32-cr16c.c: Delete. * Makefile.am, * archures.c, * config.bfd, * configure.ac, * reloc.c, * targets.c: Remove cr16c support. * Makefile.in, * bfd-in2.h, * configure, * libbfd.h, * po/SRC-POTFILES.in: Regenerate. ld/ * emulparams/elf32cr16c.sh: Delete. * scripttempl/elf32cr16c.sc: Delete. * Makefile.am, * configure.tgt: Remove cr16c support. * NEWS: Mention removal of cr16c. * Makefile.in, * po/BLD-POTFILES.in: Regenerate.
2019-11-05GENERATE_SHLIB_SCRIPT vs. EMBEDDED.Alan Modra14-18/+9
A target that sets EMBEDDED non-empty is one that doesn't want to put the ELF file header or program header in a memory image. Likely the target isn't interested in supporting dynamically loaded executables, shared libraries, or PIEs, because loaders for such binaries generally require program headers to be present. This isn't 100% true though. The target might be one where the loader accesses the file system in order to retrieve headers. Also, note that not all "shared libraries" require gcc -shared or the shared library support in the linker. I believe one implementation of shared libraries on uclinux is like this. So, this patch removes GENERATE_SHLIB_SCRIPT and GENERATE_PIE_SCRIPT in most emulparams files where EMBEDDED is set, restoring the shared lib and pie support in emulparams files that unset EMBEDDED after including a file where the support is removed. Exceptions to the general rule that EMBEDDED disables shared libs are: arm*-*-symbianelf*, where the OS wants shared library support without ELF program headers in the image, and sh*-*-uclinux*, where I've left things as they were, ie. both EMBEDDED and GENERATE_SHLIB_SCRIPT because I'm unsure as to the shared library scheme. * emulparams/aarch64elf.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Don't set. * emulparams/aarch64elf32.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Don't set. * emulparams/arcelf.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/armelf.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Don't set. * emulparams/armelf_fbsd.sh (GENERATE_SHLIB_SCRIPT): Set. * emulparams/armelf_nbsd.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Set. * emulparams/armelf_vxworks.sh (GENERATE_SHLIB_SCRIPT): Set. * emulparams/armsymbian.sh (GENERATE_SHLIB_SCRIPT): Set. * emulparams/elf32bfin.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/elf32microblaze.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/score3_elf.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/shelf.sh (GENERATE_SHLIB_SCRIPT): Don't set. * emulparams/shelf_nbsd.sh (GENERATE_SHLIB_SCRIPT), (GENERATE_PIE_SCRIPT): Set. * emulparams/shelf_uclinux.sh (GENERATE_SHLIB_SCRIPT): Set.

2019-10-16PR13616, linker should pad executable sections with nops, not zerosAlan Modra2-2/+0
This implements padding of orphan executable sections for PowerPC. Of course, the simple implementation of bfd_arch_ppc_nop_fill and removing the NOP definition didn't work, with powerpc64 hitting a testsuite failure linking to S-records. That's because the srec target is BFD_ENDIAN_UNKNOWN so the test of bfd_big_endian (abfd) in default_data_link_order therefore returned false, resulting in a little-endian nop pattern. The rest of the patch fixes that problem by adding a new field to bfd_link_info that can be used to determine actual endianness on targets like srec. PR 13616 include/ * bfdlink.h (struct bfd_link_info <big_endian>): New field. bfd/ * cpu-powerpc.c (bfd_arch_ppc_nop_fill): New function, use it for all ppc arch info. * linker.c (default_data_link_order): Pass info->big_endian to arch_info->fill function. ld/ * emulparams/elf64lppc.sh (NOP): Don't define. * emulparams/elf64ppc.sh (NOP): Don't define. * ldwrite.c (build_link_order): Use link_info.big_endian.

2019-08-09Add support for a MIPS specific .MIPS.xhash section.Mihailo Stojanovic3-0/+3
This patch is a reimplementation of [1] which was submitted in 2015 by Neil Schellenberger. Copyright issue was sorted out [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (DT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering on the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word (ngnusyms) which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS-specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue as reported in [3], which is caused by the leading word added to the .MIPS.xhash section. Leading word is removed in this patch, and the number of entries in the translation table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is addressed by the corresponding glibc patch). Suggestions on coding style in [4] were taken into account. Existing GNU hash testcase was covered, and another one was added in the MIPS part of the testsuite. The other major change is reserving MIPS ABI version 5 for .MIPS.xhash, marking the need of support for .MIPS.xhash in the dynamic linker (again, addressed in the corresponding glibc patch). This is something which I am not sure of, especially after reading [5]. I am confused on whether this ABI version is reserved for IFUNC, or it can be used for this purpose.

2019-08-07ld: use a specific linker script in BPF targetsJose E. Marchesi1-1/+2
This patch makes the elf64bpf emulation to use it's own linker script, based on elf.sc. At the moment, the only change is that the BPF executable doesn't define an entry symbol (BPF programs feature several entry points scattered in several sections.) This is a step towards the goal of generating proper ELF executables that would be loaded by the kernel's libbpf. We are not there yet: BPF "programs" should still be linked with -r. This change removes a warning while linking executables, decreases the number of unsupported tests in the target from 47 to 29, and increases the number of expected passes from 104 to 145. Regtested in x86_64 for all targets. No regressions. ld/ChangeLog: 2019-08-07 Jose E. Marchesi <jose.marchesi@oracle.com> * scripttempl/elf64bpf.sc: Adapted from elf.sc. * emulparams/elf64bpf.sh (SCRIPT_NAME): Use elf64bpf. (EMBEDDED): Define. * testsuite/ld-bpf/call-1.d: Do not expect a warning regarding an undefined entry symbol. * testsuite/ld-bpf/jump-1.d: Likewise. * testsuite/ld-undefined/undefined.exp: Do not pass '-e entry' to ld in BPF targets, and do not expect line number information. * testsuite/ld-srec/srec.exp (run_srec_test): xfail s-record tests in BPF targets.
