* RISC-V: PR28789, Reject R_RISCV_PCREL relocations with ABS symbol in PIC/PIE.Palmer Dabbelt2023-03-308-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The non-preemptible SHN_ABS symbol with a pc-relative relocation should be disallowed when generating shared object (pic and pie). Generally, the following cases, which refer to pr25749, will cause a symbol be non-preemptible, * -pie, or -shared with -symbolic * STV_HIDDEN, STV_INTERNAL, STV_PROTECTED * Have dynamic symbol table, but without the symbol * VER_NDX_LOCAL However, PCREL_HI20/LO12 relocs are always bind locally when generating shared object, so not only the non-preemptible absolute symbol need to be disallowed, all absolute symbol references need but except that they are defined in linker script. If we also disallow the absolute symbol in linker script, then the glibc-linux toolchain build failed, so regard them as pc-relative symbols, just like what x86 did. Maybe we should add this check for all pc-relative relocations, rather than just handle in R_RISCV_PCREL relocs. Ideally, since the value of SHN_ABS symbol is a constant, only S - A relocations should be allowed in the shared object, so only BFD_RELOC_8/16/32/64 are allowed, which means R_RISCV_32/R_RISCV_64. bfd/ PR 28789 * elfnn-riscv.c (riscv_elf_check_relocs): The absolute symbol cannot be referneced with pc-relative relocation when generating shared object. ld/ PR 28789 * ld/testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated. * ld/testsuite/ld-riscv-elf/pcrel-reloc*: New testcases.
* RISC-V: Clarify link behaviors of R_RISCV_32/64 relocations with ABS symbol.Nelson Chu2023-03-3013-2/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two improvements, which are all referenced to aarch64, * R_RISCV_32 with non ABS symbol cannot be used under RV64 when making shard objects. * Don't need dynamic relocation for R_RISCV_32/64 under RV32/RV64 when making shared objects, if the referenced symbol is local ABS symbol. However, considering this link, https://github.com/riscv-non-isa/riscv-elf-psabi-doc/issues/341 Seems like we should makes all R_RISCV_32/64 relocs with ABS symbol that don't need any dynamic relocations when making the shared objects. But anyway, I just sync the current behavior as aarch64 ld, in case there are any unexpected behaviors happen. Passed the gcc/binutils regressions in riscv-gnu-toolchain. bfd/ * elfnn-riscv.c (riscv_elf_check_relocs): Only allow R_RISCV_32 with ABS symbol under RV64. (riscv_elf_relocate_section): R_RISCV_32/64 with local ABS symbol under RV32/RV64 doesn't need any dynamic relocation when making shared objects. I just make the implementations similar to other targets, so that will be more easy to mainatain. ld/ * testsuite/ld-riscv-elf/data-reloc*: New testcases. * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Added new data-reloc* testcases, and need to make ifunc-seperate* testcases work for rv32. * testsuite/ld-riscv-elf/ifunc-seperate-caller-nonplt.s: Likewise. * testsuite/ld-riscv-elf/ifunc-seperate-caller-plt.s: Likewise.
* ld testsuite CFLAGS_FOR_TARGETAlan Modra2023-03-292-11/+7
| | | | | | | | | | | | | | | | | | | run_host_cmd adds $gcc_B_opt and $ld_L_opt to the command line if it detects the program being run is a compiler. Since the program being run in lto.exp linking pr28138 is "sh", we need to add these by hand. This isn't exactly as run_host_cmd does, as it lacks reordering of any user -B option in $CC_FOR_TARGET, but it's better than ignoring gcc_B_opt. This fixes a mips64 testsuite fail. ld_compile adds CFLAGS_FOR_TARGET and other flags as well, so there is no need for the ld_compile command line to include CFLAGS_FOR_TARGET. Fixing this is just a tidy. * testsuite/ld-plugin/lto.exp: Add gcc_B_opt, CFLAGS_FOR_TARGET and $ld_L_opt to pr28138 link line. * testsuite/lib/ld-lib.exp (run_ld_link_tests): Don't pass unnecessary flags to ld_compile.

* Use stdint types in coff internal_auxentAlan Modra2023-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | long is a poor choice of type to store 32-bit values read from objects files by H_GET_32. H_GET_32 doesn't sign extend so tests like that in gdb/coffread.c for "negative" values won't work if long is larger than 32 bits. If long is 32-bit then code needs to be careful to not accidentally index negative array elements. (I'd rather see a segfault on an unmapped 4G array index than silently reading bogus data.) long is also a poor choice for x_sect.s_scnlen, which might have 64-bit values. It's better to use unsigned exact width types to avoid surprises. I decided to change the field names too, which makes most of this patch simply renaming. Besides that there are a few places where casts are no longer needed, and where printf format strings or tests need adjusting. include/ * coff/internal.h (union internal_auxent): Use unsigned stdint types.

* bfd: aarch64: Fix stubs that may break BTI PR30076Szabolcs Nagy2023-03-235-0/+192
| | | | | | | | | | | | | | Insert two stubs in a BTI enabled binary when fixing long calls: The first is near the call site and uses an indirect jump like before, but it targets the second stub that is near the call target site and uses a direct jump. This is needed when a single stub breaks BTI compatibility. The stub layout is kept fixed between sizing and building the stubs, so the location of the second stub is known at build time, this may introduce padding between stubs when those are relaxed. Stub layout with BTI disabled is unchanged.

* Re: Add --enable-linker-version optionChristophe Lyon2023-03-162-2/+2
| | | | | | | | | | | | | | | | | | | | The recently-added ld-version*.d tests expect .*GNU ld \(GNU Binutils\) 2.* in the .comment section. However, when buidling --with-pkgversion=XXX, we get GNU ld (XXX) 2.[...] instead, leading to a spurious FAIL. This small patch replaces "GNU Binutils" with ".*" instead. I inspected other testcases to see if we already had similar occurrences but I couldn't see any, so I hope this fix is OK for the purpose? Thanks, Christophe

* PR30155, ld segfault in _bfd_nearby_sectionAlan Modra2023-02-241-13/+52
| | | | | | | | | | | | | | | | | The segfault was a symptom of messing with the absolute section next field, confusing bfd_section_removed_from_list in linker.c:fix_syms. That's not all that was going wrong. The INSERT list of output sections was being inserted into itself, ie. lost from the main list of linker statements. PR 30155 * ldlang.c (process_insert_statements): Handle pathological case of the insert script being inserted before the first output section statement in the default script. (output_prev_sec_find): Don't test section owner here. (insert_os_after): Change parameter to a list union pointer. (lang_insert_orphan): Test section owner here and adjust insert_os_after call.
* RISC-V: Add --[no-]relax-gp to ldFangrui Song2023-02-236-1/+69
| | | | | | | | | | | | | | | | | | | | | | | | | --relax enables all relaxations. --no-relax-gp disables GP relaxation to allow measuring its effect. The option can test effectiveness of GP relaxation and support some ABI variants that use GP for other purposes.

* ld/testsuite: don't output to /dev/nullClément Chigot2023-02-211-1/+3
| | | | | | | | | | | | Mingw doesn't have /dev/null and thus "-o /dev/null" will fail. Currently, all the options are checked using this "-o /dev/null", resulting in them being disabled on mingw hosts. Fix that by outputting to a real file for all targets. ld/ChangeLog: * testsuite/config/default.exp: Replace "-o /dev/null" by a file.

* ld/testsuite: handle Windows drive letter in a noinit testClément Chigot2023-02-201-2/+2
| | | | | | | | | | | The regexp in "noinit sections (ld -r)" is skipping the file path before the first ":". However, on Windows, a path can start with "C:". Adjust the regexp to allow such cases. ld/ChangeLog: * testsuite/ld-elf/noinit-sections-2.l: Allow Windows paths (starting with C:).
* ld/testsuite: adjust to Windows path separator.Clément Chigot2023-02-207-7/+7
| | | | | | | | | | | | | | | | In some tests, the path reported on Windows will have a \ instead of a /. This occurs when a file is concatened with the search path in ldfile.c.: "ld -Ltmpdir -ltext" will result into "tmpdir\libtext.a". ld/ChangeLog: * testsuite/ld-elf/retain5.map: Allow \ path separator. * testsuite/ld-plugin/plugin-10.d: Likewise. * testsuite/ld-plugin/plugin-11.d: Likewise. * testsuite/ld-plugin/plugin-18.d: Likewise. * testsuite/ld-plugin/plugin-19.d: Likewise. * testsuite/ld-plugin/plugin-20.d: Likewise. * testsuite/ld-plugin/plugin-22.d: Likewise.
