2023-09-29x86-64: Add -z mark-plt and -z nomark-pltH.J. Lu
The PLT entry in executables and shared libraries contains an indirect branch, like jmp *foo@GOTPCREL(%rip) push $index_foo jmp .PLT0 or endbr64 jmp *foo@GOTPCREL(%rip) NOP padding which is used to branch to the function, foo, defined in another object. Each R_X86_64_JUMP_SLOT relocation has a corresponding PLT entry. The dynamic tags have been added to the x86-64 psABI to mark such PLT entries: https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/6d824a52a42d173eb838b879616c1be5870b593e Add an x86-64 linker option, -z mark-plt, to mark PLT entries with #define DT_X86_64_PLT (DT_LOPROC + 0) #define DT_X86_64_PLTSZ (DT_LOPROC + 1) #define DT_X86_64_PLTENT (DT_LOPROC + 3) 1. DT_X86_64_PLT: The address of the procedure linkage table. 2. DT_X86_64_PLTSZ: The total size, in bytes, of the procedure linkage table. 3. DT_X86_64_PLTENT: The size, in bytes, of a procedure linkage table entry. and set the r_addend field of the R_X86_64_JUMP_SLOT relocation to the memory offset of the indirect branch instruction.

2023-08-03readelf sprintf optimisationAlan Modra
This replaces sprintf and strcat calls with stpcpy, and makes use of sprintf return value rather than using strlen, for get_machine_flags. decode_NDS32_machine_flags made use of snprintf, which is arguably the "correct" way to do things if there can be a buffer overflow. In this case I don't think there can be, the buffer is 1k in size which is at least 5 times more than needed. What's more, snprintf returns the count of chars that would be output given no buffer limit, which means code like r += snprintf (buf + r, size - r, ...); r += snprintf (buf + r, size - r, ...); is just wrong. There needs to be a check on the return value in order to prevent buf + r being out of bounds for the second snprintf call. BTW, if you look closely you'll see the return value of the decode functions is unused. I admit to getting a little carried away with writing "out = stpcpy (out, ...):" in each of the decode functions and didn't notice that until get_machine_flags was trimmed down to a much smaller size. When I did notice, I decided it's not such a bad thing. * readelf.c (decode_ARC_machine_flags, decode_ARM_machine_flags), (decode_AVR_machine_flags, decode_NDS32_machine_flags), (decode_AMDGPU_machine_flags): Use stpcpy and sprintf return value.

2023-07-30bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flagsJose E. Marchesi
This patch adds support for EF_BPF_CPUVER bits in the ELF machine-dependent header flags. These bits encode the BPF CPU version for which the object file has been compiled for. The BPF assembler is updated so it annotates the object files it generates with these bits. The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the appropriate ISA version if the user didn't specify an explicit ISA version in the command line. Note that a value of zero in EF_BPF_CPUVER is interpreted by the disassembler as "use the later supported version" (the BPF CPU versions start with v1.) The readelf utility is updated to pretty print EF_BPF_CPUVER when it prints out the ELF header: $ readelf -h a.out ELF Header: ...

2023-07-28MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targetsYunQiang Su
Make the n64 ABI the default for 64-bit Linux targets specified with `-gnuabi64' suffix included in the target triplet, for configurations such as the Debian mips64el and mips64r6el ports. Adjust testsuite configuration accordingly. There are the following regressions with the new target triplet: mips64-linux-gnuabi64 +FAIL: readelf -S bintest mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 mips64el-linux-gnuabi64 +FAIL: readelf -S bintest mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 The `readelf' issue comes from a difference in section headers produced that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template does not match. While there has been a precedent it does not appear to me that there is a clear advantage from adding more and more variations to the template rather than forking the existing template into multiple ones for a more exact match. So this is best deferred to a separate discussion. The MIPS reloc estimation issue is an actual bug in `objdump', which discards a number of trailing entries from output here for n64 composed relocations: DYNAMIC RELOCATION RECORDS OFFSET TYPE VALUE 0000000000000000 R_MIPS_NONE *ABS* 0000000000000000 R_MIPS_NONE *ABS* and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not match even though ELF output produced is correct according to `readelf': Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries: Offset Info Type Sym.

The presence of these extra R_MIPS_NONE entries is not relevant for generic or even some MIPS tests, so optionally match them with the respective dump patterns, also discarding `xfail' annotation for MIPS/OpenBSD targets from gas/elf/missing-build-notes.d, removing these regressions: mips64-openbsd -FAIL: readelf -r bintest mips64-openbsd -FAIL: forward expression mips64-openbsd -FAIL: assignment tests mips64-openbsd -FAIL: gas/all/none mips64-openbsd -XFAIL: gas/elf/missing-build-notes mips64-openbsd -FAIL: macro test 2 mips64-openbsd -FAIL: macro irp mips64-openbsd -FAIL: macro rept mips64-openbsd -FAIL: nested irp/irpc/rept mips64-openbsd -FAIL: macro vararg mips64-openbsd -FAIL: mips jalx mips64-openbsd -FAIL: ST Microelectronics Loongson-2F workarounds of Jump Instruction issue mips64el-openbsd -FAIL: readelf -r bintest mips64el-openbsd -FAIL: forward expression mips64el-openbsd -FAIL: assignment tests mips64el-openbsd -FAIL: gas/all/none mips64el-openbsd -XFAIL: gas/elf/missing-build-notes mips64el-openbsd -FAIL: macro test 2 mips64el-openbsd -FAIL: macro irp mips64el-openbsd -FAIL: macro rept mips64el-openbsd -FAIL: nested irp/irpc/rept mips64el-openbsd -FAIL: macro vararg mips64el-openbsd -FAIL: mips jalx mips64el-openbsd -FAIL: ST Microelectronics Loongson-2F workarounds of Jump Instruction issue Co-Authored-By: Maciej W.

2023-07-28Revert "MIPS: support mips*64 as CPU and gnuabi64 as ABI"Maciej W. Rozycki
This reverts commit 32f1c80375ebe8ad25d9805ee5889f0006c51e59. It had two unrelated changes lumped together, one of which changed the meaning of the `mipsisa64*-*-linux*' target triplets, which was not properly evaluated.
2023-07-28coff/pe/xcoff and --extract-symbolsAlan Modra
This fixes failure of the "extract symbols" test for rs6000, where --extract-symbols generates a non-zero sized .text. By the look of coffcode.h the same problem might occur for coff/pe too, but doesn't happen to trigger a test failure. bfd/ * coffcode.h (coff_compute_section_file_positions): Don't adjust size of !SEC_LOAD sections. binutils/ * objcopy.c (setup_section): Clear SEC_LOAD for --extract-symbol.

2023-07-19Tidy binutils configureAlan Modra
Separate out some of the defines from the block handling windows support, so they don't get lost. Delete an unused variable.

Only the xcoff and pe extensions were enabled. Build the lot, and fix some more printf format problems when the host is 32-bit. * configure.ac (od_vectors): Set up for --enable-targets=all. * configure: Regenerate. * od-elf32_avr.c (elf32_avr_dump_mem_usage): Correct format specifier vs. arg mismatch. (elf32_avr_dump_avr_prop): Likewise.
