2023-08-23x86: Fix DT_JMPREL/DT_PLTRELSZ when relocs share a sectionPeter Edwards8-0/+36
If a linker script does not place the PLT relocations and "normal" relocations in separate ELF sections, `ld` will currently output incorrect values for DT_JMPREL and DT_PLTRELSZ - they cover the entire ELF section, rather than just the PLT relocations Don't ignore the extent of the BFD section - use the size of the srelplt BFD section and its offset from the output_secttion bfd/ PR ld/30787 * elfxx-x86.c (_bfd_x86_elf_finish_dynamic_sections): Use input section for DT_JMPREL and DT_PLTRELSZ. ld/ PR ld/30787 * testsuite/ld-i386/i386.exp: Run pr30787. * testsuite/ld-x86-64/x86-64.exp: Likewise. * testsuite/ld-i386/pr30787.d: New file. * testsuite/ld-i386/pr30787.s: Likewise. * testsuite/ld-i386/pr30787.t: Likewise. * testsuite/ld-x86-64/pr30787.d: Likewise. * testsuite/ld-x86-64/pr30787.s: Likewise. * testsuite/ld-x86-64/pr30787.t: Likewise.

2023-07-28MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targetsYunQiang Su4-8/+20
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.

2023-07-28testsuite: Handle composed R_MIPS_NONE relocationsYunQiang Su1-0/+4
MIPS n64 ABI has a peculiarity where all relocations are composed of three, with subsequent relocation types set to R_MIPS_NONE if further calculation is not required. Example output produced by `readelf' and `objdump' for such relocations is: Offset Info Type Sym. Value Sym. Name + Addend 000000000000 000800000002 R_MIPS_32 0000000000000000 foo + 0 Type2: R_MIPS_NONE Type3: R_MIPS_NONE and: OFFSET TYPE VALUE 0000000000000000 R_MIPS_32 foo 0000000000000000 R_MIPS_NONE *ABS* 0000000000000000 R_MIPS_NONE *ABS* respectively. 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.

The `mips-sgi-irix6' target only supports IRIX linker emulations, but most JALR relaxation tests request the relevant traditional emulation instead, causing a link failure: ./ld-new: unrecognised emulation mode: elf32btsmipn32 Supported emulations: elf32bmipn32 elf32bsmip elf64bmip This is clearly an omission from the conversion to use the per-ABI framework made with commit 78da84f99405 ("MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement"). These tests are also endianness agnostic, which was missed in the conversion as well.

There are only n64 linker emulations included with `mips64*-*-openbsd*' targets, however the unaligned JALX tests insist on running across all targets and force the n32 ABI, causing link errors with the targets concerned, e.g.: ./ld-new: tmpdir/unaligned-jalx-0.o: ABI is incompatible with that of the selected emulation ./ld-new: failed to merge target specific data of file tmpdir/unaligned-jalx-0.o ./ld-new: tmpdir/unaligned-insn.o: ABI is incompatible with that of the selected emulation ./ld-new: failed to merge target specific data of file tmpdir/unaligned-insn.o Convert the tests then to use the per-ABI framework and run them for the o32 and n32 ABIs, removing these regressions: mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 0 mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 1 mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 2 mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 3 mips64-openbsd -FAIL: MIPS16 JALX to unaligned symbol 0 mips64-openbsd -FAIL: MIPS16 JALX to unaligned symbol 1 mips64-openbsd -FAIL: microMIPS JALX to unaligned symbol 0 mips64-openbsd -FAIL: microMIPS JALX to unaligned symbol 1 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 0 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 1 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 2 mips64el-openbsd -FAIL: MIPS JALX to unaligned symbol 3 mips64el-openbsd -FAIL: MIPS16 JALX to unaligned symbol 0 mips64el-openbsd -FAIL: MIPS16 JALX to unaligned symbol 1 mips64el-openbsd -FAIL: microMIPS JALX to unaligned symbol 0 mips64el-openbsd -FAIL: microMIPS JALX to unaligned symbol 1 Similar tests for the n64 ABI can be added separately, using suitable dump patterns. ld/ * testsuite/ld-mips-elf/unaligned-jalx-0.d: Remove `-32' from the `as' tag. * testsuite/ld-mips-elf/unaligned-jalx-1.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-2.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-3.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-mips16-0.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-mips16-1.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-micromips-0.d: Likewise. * testsuite/ld-mips-elf/unaligned-jalx-micromips-1.d: Likewise. * testsuite/ld-mips-elf/mips-elf.exp: Run unaligned JALX tests with `run_dump_test_o32' and `run_dump_test_n32' rather than `run_dump_test'.

In ld/emulparams/elf64bmip-defs.sh there is no explicit handling of the `.interp' section, which causes it to be positioned in output at an odd place.

2023-07-21DesCGENization of the BPF binutils portJose E. Marchesi4-7/+7
CGEN is cool, but the BPF architecture is simply too bizarre for it. The weird way of BPF to handle endianness in instruction encoding, the weird C-like alternative assembly syntax, the weird abuse of multi-byte (or infra-byte) instruction fields as opcodes, the unusual presence of opcodes beyond the first 32-bits of some instructions, are all examples of what makes it a PITA to continue using CGEN for this port. The bpf.cpu file is becoming so complex and so nested with p-macros that it is very difficult to read, and quite challenging to update. Also, every time we are forced to change something in CGEN to accommodate BPF requirements (which is often) we have to do extensive testing to make sure we do not break any other target using CGEN. This is getting un-maintenable. So I have decided to bite the bullet and revamp/rewrite the port so it no longer uses CGEN. Overall, this involved: * To remove the cpu/bpf.{cpu,opc} descriptions. * To remove the CGEN generated files. * To replace the CGEN generated opcodes table with a new hand-written opcodes table for BPF. * To replace the CGEN generated disassembler wih a new disassembler that uses the new opcodes. * To replace the CGEN generated assembler with a new assembler that uses the new opcodes. * To replace the CGEN generated simulator with a new simulator that uses the new opcodes. [This is pushed in GDB in another patch.] * To adapt the build systems to the new situation. Additionally, this patch introduces some extensions and improvements: * A new BPF relocation BPF_RELOC_BPF_DISP16 plus corresponding ELF relocation R_BPF_GNU_64_16 are added to the BPF BFD port. These relocations are used for section-relative 16-bit offsets used in load/store instructions. * The disassembler now has support for the "pseudo-c" assembly syntax of BPF. What dialect to use when disassembling is controlled by a command line option. * The disassembler now has support for dumping instruction immediates in either octal, hexadecimal or decimal. The used output base is controlled by a new command-line option. * The GAS BPF test suite has been re-structured and expanded in order to test the disassembler pseudoc syntax support. Minor bugs have been also fixed there. The assembler generic tests that were disabled for bpf-*-* targets due to the previous implementation of pseudoc syntax are now re-enabled. Additional tests have been added to test the new features of the assembler. .dump files are no longer used. * The linker BPF test suite has been adapted to the command line options used by the new disassembler. The result is very satisfactory. This patchs adds 3448 lines of code and removes 10542 lines of code. Tested in: * Target bpf-unknown-none with 64-bit little-endian host and 32-bit little-endian host. * Target x86-64-linux-gnu with --enable-targets=all Note that I have not tested in a big-endian host yet. I will do so once this lands upstream so I can use the GCC compiler farm. I have not included ChangeLog entries in this patch: these would be massive and not very useful, considering this is pretty much a rewrite of the port. I beg the indulgence of the global maintainers.

2023-07-17Support NEXT_SECTION in ALIGNOF and SIZEOFAlan Modra2-2/+2
This patch is aimed at making __bss_start properly aligned with the first of any bss-style sections following. Most of the work here involves keeping track of the last output section seen when processing the linker script. You can almost align __bss_start properly by using ${RELOCATING+. = ALIGN(${DATA_SDATA-${NO_SMALL_DATA-ALIGNOF(.${SBSS_NAME}) != 0 ? ALIGNOF(.${SBSS_NAME}) : }}${BSS_PLT+ALIGNOF(.plt) != 0 ? ALIGNOF(.plt) : }ALIGNOF(.${BSS_NAME}));} and changing every place that defines NO_SMALL_DATA to use " ", but having two .plt sections (marked SPECIAL) on some backends foils that idea. The problem is that you only want to pick up the following .plt, not the one preceeding __bss_start in the data segment if the backend decides that is the proper .plt section. Perhaps that could be fixed too, but I decided instead to extend the linker script a little.

2023-07-06Use run_host_cmd to run $CC and other no-section-header test fixesAlan Modra7-54/+54
We should be using run_host_cmd everywhere we invoke a compiler in the ld testsuite, if we want to use ld/ld-new just built. run_host_cmd properly inserts $gcc_B_opt in cases where a user wants to test binutils with a newly built compiler, ie. when $CC specifies -B itself.

The additional hex notation was minimally useful when one had to inspect code with heavy bit manipulation, or of unclear signedness, but it clutters the output, and the style is not regular assembly language syntax either.

2023-06-30LoongArch: support disassembling certain pseudo-instructionsWANG Xuerui4-17/+17
Add a flag in the pinfo field for being able to mark certain specialized matchers as disassembler-only, so some degree of isolation between assembler-side and disassembler-side can be achieved. This isolation is necessary, firstly because some pseudo-instructions cannot be fully described in the opcode table, like `li.[wd]`, so the corresponding opcode entry cannot have meaningful match/mask values. Secondly, some of these pseudo-instructions can be realized in more than one plausible ways; e.g. `li.w rd, <something between 0 and 0x7ff>` can be realized on LA64 with any of `addi.w`, `addi.d` or `ori`. If we tie disassembly of such aliases with the corresponding GAS support, only one canonical form among the above would be recognized as `li.w`, and it would mildly impact the readability of disassembly output. People wanting the exact disassembly can always set `-M no-aliases` to get the original behavior back. In addition, in certain cases, information is irreversibly lost after assembling, so perfect round-trip would not be possible in such cases. For example, `li.w` and `li.d` of immediates within int32_t range produce the same code; in this patch, `addi.d rd, $zero, imm` is treated as `li.d`, while `addi.w` and `ori` immediate loads are shown as `li.w`, due to the expressible value range well within 32 bits. gas/ChangeLog: * config/tc-loongarch.c (get_loongarch_opcode): Ignore disassembler-only aliases. * testsuite/gas/loongarch/64_pcrel.d: Update test case. * testsuite/gas/loongarch/imm_ins.d: Likewise. * testsuite/gas/loongarch/imm_ins_32.d: Likewise. * testsuite/gas/loongarch/jmp_op.d: Likewise. * testsuite/gas/loongarch/li.d: Likewise. * testsuite/gas/loongarch/macro_op.d: Likewise. * testsuite/gas/loongarch/macro_op_32.d: Likewise. * testsuite/gas/loongarch/macro_op_large_abs.d: Likewise. * testsuite/gas/loongarch/macro_op_large_pc.d: Likewise. * testsuite/gas/loongarch/nop.d: Likewise. * testsuite/gas/loongarch/relax_align.d: Likewise. * testsuite/gas/loongarch/reloc.d: Likewise. include/ChangeLog: * opcode/loongarch.h (INSN_DIS_ALIAS): Add. ld/ChangeLog: * testsuite/ld-loongarch-elf/jmp_op.d: Update test case. * testsuite/ld-loongarch-elf/macro_op.d: Likewise. * testsuite/ld-loongarch-elf/macro_op_32.d: Likewise. * testsuite/ld-loongarch-elf/relax-align.dd: Likewise. opcodes/ChangeLog: * loongarch-dis.c: Move register name map declarations to top.

2023-06-29sframe: bfd: gas: ld: format bump to SFrame version 2Indu Bhagat3-5/+5
SFrame version 2 encodes the size of repetitive insn block explicitly in the format. Add information in the SFrame FDE to convey the size of the block of repeating instructions. This information is used only for SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK. Introduce two extra bytes for padding: this ensures that the memory accesses to the members of the SFrame Frame Descriptor Entry (FDE) are naturally aligned. gas generates SFrame section with version SFRAME_VERSION_2 by default. libsframe provides two new APIs to: - get an SFrame FDE data from the decoder context, and - add an SFrame FDE to the encoder context. The additional argument (for rep_block_size) is useful for SFrame FDEs where FDE type is SFRAME_FDE_TYPE_PCMASK. The linker will generate the output SFrame sections in the SFRAME_VERSION_2 format. If the input sections offered to the linker are not all in the SFRAME_VERSION_2 format, the linker issues an error to the user. objdump/readelf will show the following message to the user if .sframe section in SFRAME_VERSION_1 format is seen: "No further information can be displayed. SFrame version not supported."

2023-06-15Re: Add some expected failures for bfin linker testsAlan Modra16-17/+19
After commit 7ade0f1582c4 I was seeing bfin-elf +XPASS: weak symbols, and on looking into the bfin targets a little, discovered we have two bfin-linux targets. One, bfin-uclinux, is like bfin-elf in that ld -m elf32bfin is the default, and the other, bfin-linux-uclibc where ld -m elf32bfinfd is the default. So putting bfin-*-*linux* in test xfails or elsewhere is wrong. We want bfin-*-linux* instead to just select the fdpic bfin target. This patch corrects wrong bfin target triples in the ld testsuite, not just the recent change but others I'd added to xfails too. It also fixes the bfin-linux-uclibc ld-elf/64ksec fail
