Power10 stub selection This patch better supports mixing of power10 and non-power10 code, as might be seen in a cpu-optimized library using ifuncs to select functions optimized for a given cpu. Using -Wl,--no-power10-stubs isn't that good in this situation since non-power10 notoc stubs are slower and larger than the power10 variants, which you'd like to use on power10 code paths. With this change, power10 pc-relative code that makes calls marked @notoc uses power10 stubs if stubs are necessary, and other calls use non-power10 instructions in stubs. This will mean that if gcc is generating code for -mcpu=power10 but with pc-rel disabled then you'll get the older stubs even on power10 (unless you force with -Wl,--power10-stubs). That shouldn't be too big a problem: stubs that use r2 are reasonable. It's just the ones that set up addressing using "mflr 12; bcl 20,31,.+4; mflr 11; mtlr 12" that should be avoided if possible. bfd/ * elf64-ppc.c (struct ppc_link_hash_table): Add has_power10_relocs.

mmix bfd: fix bfd_assert for R_MMIX_PUSHJ_STUBBABLE against undef'd symbol Spotted when inspecting gcc testsuite logs, but this already is covered by the ld-mmix testsuite, it's just that the assert is ignored since the regexp match is for a substring and not anchored. With the anchors added but not the bugfix, the ld.log shows that the asserts cause a non-match as intended: Executing on host: sh -c {./ld-new -LX/src/ld/testsuite/ld-mmix -m elf64mmix -o tmpdir/dump tmpdir/undef-2.o tmpdir/start.o 2>&1} /dev/null dump.tmp (timeout = 300) ./ld-new: BFD (GNU Binutils) 2.34.50.20200629 assertion fail X/src/bfd/elf64-mmix.c:2845 ./ld-new: BFD (GNU Binutils) 2.34.50.20200629 assertion fail X/src/bfd/elf64-mmix.c:2845 ./ld-new: BFD (GNU Binutils) 2.34.50.20200629 assertion fail X/src/bfd/elf64-mmix.c:2845 ./ld-new: tmpdir/undef-2.o:(.text+0x0): undefined reference to `undefd' failed with: <./ld-new: BFD (GNU Binutils) 2.34.50.20200629 assertion fail X/src/bfd/elf64-mmix.c:2845 ./ld-new: BFD (GNU Binutils) 2.34.50.20200629 assertion fail X/src/bfd/elf64-mmix.c:2845 ./ld-new: BFD (GNU Binutils) 2.34.50.20200629 assertion fail X/src/bfd/elf64-mmix.c:2845 ./ld-new: tmpdir/undef-2.o:(.text+0x0): undefined reference to `undefd'>, expected: <\A[^\n\r]*undefined reference to `undefd'\Z> FAIL: ld-mmix/undef-2 Gone with the fix of course, leaving just the intended "undefined reference" line. I'm not going to add anchors manually for all the "error:" strings in the test-suite, not even in the mmix parts. Sorry, but I'll just do it for *these* specific undefined-reference tests. Just a thought: maybe the run_dump_test "error:" string should *automatically* get anchor marks prepended and appended for a single line match as in the patch, "\A[^\n\r]*" prepended and \Z appended unless either anchor mark or \r or \n is present in the regexp? Committed. bfd: * elf64-mmix.c (mmix_elf_relax_section): Improve accounting for R_MMIX_PUSHJ_STUBBABLE relocs against undefined symbols. ld/testsuite: * testsuite/ld-mmix/undef-1.d, testsuite/ld-mmix/undef-1m.d, testsuite/ld-mmix/undef-2.d, testsuite/ld-mmix/undef-2m.d: Add start- and end-anchors to error-string to match just a single-line error-message.

RISCV changes broke 32-bit --enable-targets=all By the look of it, git commit 39ff0b812324 broke 32-bit host --enable-targets=all binutils builds. /usr/local/bin/ld: ../opcodes/.libs/libopcodes.a(riscv-dis.o): in function `parse_riscv_dis_option': /home/alan/src/binutils-gdb/opcodes/riscv-dis.c:102: undefined reference to `riscv_get_priv_spec_class' collect2: error: ld returned 1 exit status Makefile:925: recipe for target 'objdump' failed The problem is that elfxx-riscv.c is not built for a 32-bit host without --enable-64-bit-bfd or unless RISCV is given specifically as a target. No such trimming of 64-bit only targets is done in opcodes. One solution is to move these support functions to cpu-riscv.c, which runs into "error: implicit declaration of function ‘xmalloc’". Now, xmalloc is not supposed to be used in libbfd or libopcodes - it's rude to crash out of an application that calls libbfd or libopcodes functions without giving it a chance to deal with out-of-memory itself. So I removed the xmalloc and instead used a fixed size buffer. If you are worried about adding 36 bytes for the buffer to the riscv_get_priv_spec_class_from_numbers stack frame size, then you have no idea of the likely xmalloc + malloc stack frame size! Trying to reduce memory usage is commendable, but in this instance riscv_estimate_digit and malloc for a temp buffer uses a lot more memory than a fixed max-size buffer. * elfxx-riscv.c (struct priv_spec_t, priv_specs), (riscv_get_priv_spec_class, riscv_get_priv_spec_class_from_numbers), (riscv_get_priv_spec_name): Move to.. * cpu-riscv.c: ..here.

bfd/riscv: tighten matching rules in riscv_scan The following GDB behaviour was observed: (gdb) x/1i 0x0001014a 0x1014a <main+8>: jal 0x10132 <foo> (gdb) show architecture The target architecture is set automatically (currently riscv:rv32) (gdb) set architecture riscv:rv32 The target architecture is assumed to be riscv:rv32 (gdb) x/1i 0x0001014a 0x1014a <main+8>: 0x37e5 (gdb) Notice that initially we can disassemble the instruction (it's a compressed jal instruction), but after setting the architecture we can no longer disassemble the instruction. This is particularly puzzling as GDB initially thought the architecture was 'riscv:rv32', but when we force the architecture to be that, the disassembly stops working. This issue was introduced with this commit: commit c35d018b1a5ec604e49a807402c4205530b25ca8 Date: Mon Jan 27 15:19:30 2020 -0800 RISC-V: Fix gdbserver problem with handling arch strings. In this commit we try to make riscv_scan handle cases where we see architecture strings like 'riscv:rv32imc' (for example). Normally this wouldn't match as bfd_default_scan requires an exact match, so we extended riscv_scan to ignore trailing characters. Unfortunately the default riscv arch is called 'riscv', is 64-bit, and has its mach type set to 0, which I think is intended to pair with code is riscv-dis.c:riscv_disassemble_insn that tries to guess if we are 32 or 64 bit. What happens then is that 'riscv:rv32' is first tested against 'riscv' using bfd_default_scan, this doesn't match, we then compare this to 'riscv', but allowing trailing characters to be ignored, this matches, and our 'riscv:rv32' matches against the default (64-bit) architecture. The solution I propose is to prevent the default architecture from taking part in this "ignore trailing characters" extra match case, only the more specific 'riscv:rv32' and 'riscv:rv64' get this extra matching. bfd/ChangeLog: * cpu-riscv.c (riscv_scan): Don't allow shorter matches using the default architecture.

RISC-V: Report warning when linking the objects with different priv specs. We do know some conflicts among different privileged specs. For linker, the safest approach is that don't allow the object linked with others which may cause conflicts. But this may cause inconvenience since not all objects with conflicting priv specs are linked will cause problems. But it is hard to know the detailed conflict cases for linker, so we probably need a option to tell linker that we do know there are no conflicts, or we are willing to take risks to link the objects with conflicted priv specs. But the option is still under discussion. Therefore, we can report warnings rather than errors when linking the objects with conflicted priv specs. This not only makes the linker more flexible, but also warns people that the conflicts may happen.

be linked with others. If the first input object doesn't contain
any priv attributes, then we need to copy the setting from the

ELF: Don't check relocations in non-loaded, non-alloced sections Don't do anything special with non-loaded, non-alloced sections. In particular, any relocs in such sections should not affect GOT and PLT reference counting (ie. we don't allow them to create GOT or PLT entries), there's no possibility or desire to optimize TLS relocs, and there's not much point in propagating relocs to shared libs that the dynamic linker won't relocate. Since check_relocs is no longer called on non-loaded, non-alloced sections, remove SEC_ALLOC check.

[PATCH v2 0/9] RISC-V: Support version controling for ISA standard extensions and CSR 1. Remove the -mriscv-isa-version and --with-riscv-isa-version options. We can still use -march to choose the version for each extensions, so there is no need to add these. 2. Change the arguments of options from [1p9|1p9p1|...] to [1.9|1.9.1|...]. Unlike the architecture string has specified by spec, ther is no need to do the same thing for options. 3. Spilt the patches to reduce the burdens of review. [PATCH 3/7] RISC-V: Support new GAS options and configure options to set ISA versions to [PATCH v2 3/9] RISC-V: Support GAS option -misa-spec to set ISA versions [PATCH v2 4/9] RISC-V: Support configure options to set ISA versions by default. [PATCH 4/7] RISC-V: Support version checking for CSR according to privilege version. to [PATCH v2 5/9] RISC-V: Support version checking for CSR according to privilege spec version. [PATCH v2 6/9] RISC-V: Support configure option to choose the privilege spec version. 4. Use enum class rather than string to compare the choosen ISA spec in opcodes/riscv-opc.c. The behavior is same as comparing the choosen privilege spec. include * opcode/riscv.h: Include "bfd.h" to support bfd_boolean. (enum riscv_isa_spec_class): New enum class. All supported ISA spec belong to one of the class (struct riscv_ext_version): New structure holds version information for the specific ISA. * opcode/riscv-opc.h (DECLARE_CSR): There are two version information, define_version and abort_version. The define_version means which privilege spec is started to define the CSR, and the abort_version means which privilege spec is started to abort the CSR. If the CSR is valid for the newest spec, then the abort_version should be PRIV_SPEC_CLASS_DRAFT. (DECLARE_CSR_ALIAS): Same as DECLARE_CSR, but only for the obselete CSR. * opcode/riscv.h (enum riscv_priv_spec_class): New enum class. Define the current supported privilege spec versions. (struct riscv_csr_extra): Add new fields to store more information about the CSR. We use these information to find the suitable CSR address when user choosing a specific privilege spec. binutils * dwarf.c: Updated since DECLARE_CSR is changed. opcodes * riscv-opc.c (riscv_ext_version_table): The table used to store all information about the supported spec and the corresponding ISA versions. Currently, only Zicsr is supported to verify the correctness of Z sub extension settings. Others will be supported in the future patches.

FIXME for merging of e_flags and .gnu.attributes Code in the linker, present before the addition of .gnu.attributes support, results in shared libraries not being considered by BFD when merging e_flags and .gnu.attributes from input files to the output. That doesn't seem correct to me, but I don't know enough about all the various ABIs to change the behaviour with any confidence. So this patch merely punts on dynamic objects in merge_private_bfd_data target functions, with a FIXME for maintainer attention. I haven't excluded shared libraries from being considered where the target merge_private_bfd_data (a) already has code dealing with shared libraries, or (b) where that function just sets the output to the most constraining arch/mach combination and other fairly trivial merges, or (c) when the target has no shared library linker support.

x86: Add i386 PE big-object support The 64-bit version of binutils got support for the PE COFF BIG OBJ format a couple of years ago. The BIG OBJ format is a slightly different COFF format which extends the size of the number of section field in the header from a uint16_t to a uint32_t and so greatly increases the number of sections allowed. However the 32-bit version of bfd never got support for this. The GHC Haskell compiler generates a great deal of symbols due to it's use of -ffunction-sections and -fdata-sections. This meant that we could not build the 32-bit version of the GHC Compiler for many releases now as binutils didn't have this support. This patch adds the support to the 32-bit port of binutils as well and also does come cleanup in the code. bfd/ChangeLog: * coff-i386.c (COFF_WITH_PE_BIGOBJ): New. * coff-x86_64.c (COFF_WITH_PE_BIGOBJ): New. * config.bfd (targ_selvecs): Rename x86_64_pe_be_vec to x86_64_pe_big_vec as it not a big-endian format.

[PATCH v2 2/2] coff-go32: support extended relocations This patch extends the relocation and line number counters for coff-go32 and coff-go32-exe to 32 bits. As I understand it works the same as for PE-COFF: If the number of relocations in an object file exceeds 65534, the NRELOC field is set to 65535 and the actual number of relocations is stored in the VADDR field of the first relocation entry. Executable files have no relocations, and thus the NRELOC field is repurposed to extend NLNNO to 32-bits. bfd * coff-go32.c (COFF_GO32, IMAGE_SCN_LNK_NRELOC_OVFL) (coff_SWAP_scnhdr_in, coff_SWAP_scnhdr_out): Define.

coff-go32-exe: support variable-length stubs The stub size in GO32 executables has historically been fixed at 2048 bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if any further expansion is desired, this must first be patched in bfd. This series includes three patches: The first changes the meaning of the bfd->origin field slightly, so that target code can use this to specify an offset into the file where the actual bfd is located. The second patch then uses this to enable support for variable-sized stubs in the coff-go32-exe format. The final patch is only a cleanup, it normalizes function and variable names in coff-stgo32.c so that they all begin with the same prefix. bfd * bfdio.c (bfd_bread, bfd_tell, bfd_seek, bfd_mmap): Always add bfd->origin to file offset. * bfdwin.c (bfd_get_file_window): Likewise. * bfd.c: Clarify the use of the bfd->origin field. * bfd-in2.h: Regenerate. * coff-i386.c: Don't include go32exe.h.

bfd_cleanup for object_p The object_p (and archive_p, core_file_p) functions are not supposed to have any target specific malloc'd memory attached to the bfd on their return. This should be obvious on a failure return, but it's also true for a successful return. The reason is that even though the object_p recognises the file, that particular target may not be used and thus the bfd won't be closed calling close_and_cleanup for the target that allocated the memory. It turns out that the object_p bfd_target* return value isn't needed. In all cases except ld/plugin.c the target is abfd->xvec and with ld/plugin.c the target isn't used. So this patch returns a cleanup function from object_p instead, called in bfd_check_format_matches to tidy the bfd before trying a different target match.

elf_backend_section_flags and _bfd_elf_init_private_section_data I was looking at elf_backend_section_flags as a means of setting SEC_SMALL_DATA for .sdata, .sbss and the like, and condidered adding an asection* parameter to access the section name easily before realising that hdr->bfd_section of course makes the section available. So no new parameter needed. In fact the flagword* parameter isn't needed either, so out it goes. The patch also tidies some horrible code in _bfd_elf_new_section_hook that can change whether known ABI sections have sh_type and sh_flags set up depending on which of the bfd_make_section functions is used. (Some of those set section flags before _bfd_elf_new_section_hook is called, others leave the flags zero.) The function also had some hacks for .init_array and .fini_array to affect how _bfd_elf_init_private_section_data behaved for those sections. It's cleaner to do that in _bfd_elf_init_private_section_data. So that all goes and we now init sh_type and sh_flags for all known ABI sections in _bfd_elf_new_section_hook. _bfd_elf_init_private_section_data is changed to suit, and now doesn't just single out SHT_INIT_ARRAY and SHT_FINI_ARRAY but rather any of the special section types. The _bfd_elf_new_section_hook change resulting in +FAIL: ld-aarch64/erratum835769-843419 exposing some errors in the aarch64 backend. elfNN_aarch64_size_stubs should not be looking at linker created sections in the stub bfd.

PR25593, --as-needed breaks DT_NEEDED order with linker plugin This patch delays setting up DT_NEEDED dynamic tags until all object files and libraries have been opened and their symbols processed, rather than adding the tags while processing symbols. Tags are ordered according to the position of the associated library on the command line and linker scripts. It is still possible with --as-needed libs that are mentioned more than once for tags to be ordered according to which mention was needed. For example with "--as-needed a.so b.so c.so b.so" when b.so is not needed by a.so or any other prior object file but is needed by c.so, the order of tags will be "A C B". bfd/ PR 25593 * elf-bfd.h (struct elf_link_hash_table): Rename "loaded" to "dyn_loaded".

bfd_size_type to size_t bfd_size_type was invented a long time ago in the K&R days. Many places in binutils ought to be using size_t instead (and there are lots of places that use long or unsigned long that really ought to use size_t too). Note that you can't change everything over to size_t: A 32-bit host needs a larger type than size_t to support reading and processing of 64-bit ELF object files. This patch just tidies some of the more obvious uses of bfd_size_type that could be size_t. There no doubt are more lurking in the source. Incidentally, practically all functions used for output of object files can use size_t and don't need to worry about overflow of size expressions. If you have something like symcount * sizeof (void *) when symcount is counting symbols already in memory then you know that this expression can't overflow since the size of a symbol in memory is larger by far than that of a pointer. * aix386-core.c (aix386_core_file_p): Use size_t for "amt". * aout-target.h (object_p): Likewise. * aout-tic30.c (tic30_aout_object_p): Likewise. * aoutx.h

ELF: Add support for unique section ID to assembler Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.
