Alan Modra	fd67aa1129	Update year range in copyright notice of binutils files Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out /po/.pot which we don't update frequently.	2 years ago

Claudiu Zissulescu	d9d85c086f	Revert "arc: Add new ARCv3 ISA to BFD." This reverts commit `06e8d9861d`.	3 years ago
Claudiu Zissulescu	06e8d9861d	arc: Add new ARCv3 ISA to BFD. The new Synopsys's ARCv3 ISA is capable to run either 64-bit or 32-bit ISA. The new 32-bit ISA is not compatible with the old Synopsys ARCv1/ARCv2 ISA, however, it retains a lot of common concepts.

Alan Modra	717d4bd6d1	Generated docs and include files bfd/doc/chew.c extracts documentation from source code comments annotated with keywords, and generates much of bfd.h and libbfd.h from those same comments. The docs have suffered from people (me too) adding things like CODE_FRAGMENT to the source to put code into bfd.h without realising that CODE_FRAGMENT also puts @example around said code into the docs. So we have random senseless things in the docs. This patch fixes that problem (well, the senseless things from CODE_FRAGMENT), moves most of the code out of bfd-in.h, and improves a few chew.c features. libbfd.h now automatically gets ATTRIBUTE_HIDDEN prototypes, and indentation in bfd.h and libbfd.h is better.	3 years ago
Jan Beulich	02d44d7658	bfd+ld: when / whether to generate .c files Having been irritated by seeing bfd/elf{32,64}-aarch64.c to be re- generated in x86-only builds, I came across `769a27ade5` ("Re: bfd BLD-POTFILES.in dependencies"). I think this went slightly too far, as outside of maintainer mode dependencies will cause the subset of files to be (re-)generated which are actually needed for the build. Generating them all is only needed when wanting to update certain files under bfd/po/, i.e. in maintainer mode. In the course of looking around in an attempt to try to understand how things are meant to work, I further noticed that ld has got things slightly wrong too: BLD-POTFILES.in depending on $(BLD_POTFILES) isn't quite right (the output doesn't change when any of the enumerated files changes; it's the mere presence which matters); like in bfd it looks like we would better extend BUILT_SOURCES accordingly. Furthermore it became apparent that ld fails to enumerate the .c files generated from the .l and .y ones. While in their absence it was benign whether translatable strings in the source files were actually marked as such, this now becomes relevant. Mark respective strings at the same time, but skipping ones which look to be of interest for debugging purposes only (e.g. such used by printf() enclosed in #ifdef TRACE).	3 years ago

Alan Modra	b1c95bc4dd	Move bfd_init to bfd.c init.c contains just one function that doesn't do much. Move it to bfd.c and give it something to do, initialising static state. So far the only initialisation is for bfd.c static variables. The idea behind reinitialising state is to see whether some set of flaky oss-fuzz crashes go away. oss-fuzz stresses binutils in ways that can't occur in reality, feeding multiple testcases into the internals of binutils. So one testcase may affect the result of the next testcase. * init.c: Delete file. Move bfd_init to.. * bfd.c (bfd_init): ..here. Init static variables. * Makefile.am (BFD32_LIBS): Remove init.lo.

Alan Modra	499766a6d7	Re: The problem with warning in elf_object_p Commit `5aa0f10c42` added a per_xvec_warn array to provide support for warnings from elf_object_p (and a later patch for warnings from pe_bfd_object_p) to be cached and then only printed if the target matches. It was quite limited in the style of message supported, only one message could be printed, and didn't really meet the stated aim of only warning when a target matches: There are many other errors and warnings that can be emitted by functions called from elf_object_p. So this patch extends the error handler functions to support printing to a string buffer, extends per_xvec_warn to support multiple errors/ warnings, and hooks this all into bfd_check_format_matches. If bfd_check_format_matches succeeds then any errors/warnings are printed for the matching target. If bfd_check_format_matches fails either due to no match or to multiple matches and only one target vector produced errors, then those errors are printed. * bfd.c (MAX_ARGS): Define, use throughout.

Indu Bhagat	cf0e0a0ba9	bfd: linker: merge .sframe sections The linker merges all the input .sframe sections. When merging, the linker verifies that all the input .sframe sections have the same abi/arch. The linker uses libsframe library to perform key actions on the .sframe sections - decode, read, and create output data. This implies buildsystem changes to make and install libsframe before libbfd. The linker places the output .sframe section in a new segment of its own: PT_GNU_SFRAME. A new segment is not added, however, if the generated .sframe section is empty. When a section is discarded from the final link, the corresponding entries in the .sframe section for those functions are also deleted. The linker sorts the SFrame FDEs on start address by default and sets the SFRAME_F_FDE_SORTED flag in the .sframe section. This patch also adds support for generation of SFrame unwind information for the .plt* sections on x86_64. SFrame unwind info is generated for IBT enabled PLT, lazy/non-lazy PLT. The existing linker option --no-ld-generated-unwind-info has been adapted to include the control of whether .sframe unwind information will be generated for the linker generated sections like PLT. Changes to the linker script have been made as necessary.

Alan Modra	f7502dfe3f	PR28834, PR26946 sanity checking section size This patch provides a new function to sanity check section sizes. It's mostly extracted from what we had in bfd_get_full_section_contents but also handles compressed debug sections. Improvements are: - section file offset is taken into account, - added checks that a compressed section can be read from file. The function is then used when handling multiple .debug_* sections that need to be read into a single buffer, to sanity check sizes before allocating the buffer.

Alan Modra	5aa0f10c42	The problem with warning in elf_object_p elfcode.h can emit three warnings in elf_object_p for various things, "section extending past end of file", "corrupt string table index", and "program header with invalid alignment". The problem with doing this is that the warning can be emitted for multiple possible targets as each one is tried. I was looking at a fuzzer testcase that had an object file with 6144 program headers, 5316 of which had invalid alignment. It would be bad enough to get 5316 messages all the same, but this object was contained in an archive and resulted in 4975776 repeats. Some trimming can be done by not warning if the bfd is already marked read_only, as is done for the "section extending past end of file" warning, but that still results in an unacceptable number of warnings for object files in archives. Besides that, it is just wrong to warn about a problem detected by a target elf_object_p other than the one that actually matches. At some point we might have more target specific warnings. So what to do? One obvious solution is to remove the warnings. Another is to poke any warning strings into the target xvec, emitting them if that xvec is the final one chosen. This also has the benefit of solving the archive problem. A warning when recursing into _bfd_check_format for the first element of the archive (to find the correct target for the archive) will still be on the xvec at the point that target is chosen for the archive. However, target xvecs are read-only. Thus the need for per_xvec_warn to logically extend bfd_target with a writable field. I've made per_xvec_warn one larger than bfd_target_vector to provide one place for user code that makes private copies of target xvecs. * elfcode.h (elf_swap_shdr_in, elf_object_p): Stash potential warnings in _bfd_per_xvec_warn location. * format.c (clear_warnmsg): New function.

Youling Tang	31f6009538	bfd: Add support for LoongArch64 EFI (efi--loongarch64). This adds support for efi-loongarch64 by virtue of adding a new PEI target pei-loongarch64. This is not a full target and only exists to support EFI at this time. This means that this target does not support relocation processing and is mostly a container format. This format has been added to elf based loongarch64 targets such that efi images can be made natively on Linux. However this target is not valid for use with gas but only with objcopy. We should't limit addresses to 32-bits for 64-bit vma, otherwise there will be "RVA truncated" error when using objcopy on loongarch64. With these changes the resulting file is recognized as an efi image. Any magic number is based on the Microsoft PE specification [1]. The test results are as follows: $ make check-binutils RUNTESTFLAGS='loongarch64.exp' PASS: Check if efi app format is recognized $ objdump -h -f tmpdir/loongarch64copy.o tmpdir/loongarch64copy.o: file format pei-loongarch64 architecture: Loongarch64, flags 0x00000132: EXEC_P, HAS_SYMS, HAS_LOCALS, D_PAGED start address 0x0000000000000000 Sections: Idx Name Size VMA LMA File off Algn 0 .text 0000003c 00000000200000b0 00000000200000b0 00000200 22 CONTENTS, ALLOC, LOAD, READONLY, CODE [1] https://docs.microsoft.com/en-us/windows/win32/debug/pe-format bfd: .gitignore (pe-loongarch64igen.c): New. * Makefile.am (pei-loongarch64.lo, pe-loongarch64igen.lo, pei-loongarch64.c, pe-loongarch64igen.c): Add support. * Makefile.in: Likewise. * bfd.c (bfd_get_sign_extend_vma): Add pei-loongarch64. * coff-loongarch64.c: New file. * coffcode.h (coff_set_arch_mach_hook, coff_set_flags, coff_write_object_contents) Add loongarch64 (loongarch64_pei_vec) support. * config.bfd: Likewise. * configure: Likewise. * configure.ac: Likewise. * libpei.h (GET_OPTHDR_IMAGE_BASE, PUT_OPTHDR_IMAGE_BASE, GET_OPTHDR_SIZE_OF_STACK_RESERVE, PUT_OPTHDR_SIZE_OF_STACK_RESERVE, GET_OPTHDR_SIZE_OF_STACK_COMMIT, PUT_OPTHDR_SIZE_OF_STACK_COMMIT, GET_OPTHDR_SIZE_OF_HEAP_RESERVE, PUT_OPTHDR_SIZE_OF_HEAP_RESERVE, GET_OPTHDR_SIZE_OF_HEAP_COMMIT, PUT_OPTHDR_SIZE_OF_HEAP_COMMIT, GET_PDATA_ENTRY, _bfd_peLoongArch64_bfd_copy_private_bfd_data_common, _bfd_peLoongArch64_bfd_copy_private_section_data, _bfd_peLoongArch64_get_symbol_info, _bfd_peLoongArch64_only_swap_filehdr_out, _bfd_peLoongArch64_print_private_bfd_data_common, _bfd_peLoongArch64i_final_link_postscript, _bfd_peLoongArch64i_only_swap_filehdr_out, _bfd_peLoongArch64i_swap_aouthdr_in, _bfd_peLoongArch64i_swap_aouthdr_out, _bfd_peLoongArch64i_swap_aux_in, _bfd_peLoongArch64i_swap_aux_out, _bfd_peLoongArch64i_swap_lineno_in, _bfd_peLoongArch64i_swap_lineno_out, _bfd_peLoongArch64i_swap_scnhdr_out, _bfd_peLoongArch64i_swap_sym_in, _bfd_peLoongArch64i_swap_sym_out, _bfd_peLoongArch64i_swap_debugdir_in, _bfd_peLoongArch64i_swap_debugdir_out, _bfd_peLoongArch64i_write_codeview_record, _bfd_peLoongArch64i_slurp_codeview_record, _bfd_peLoongArch64_print_ce_compressed_pdata): New. * peXXigen.c (_bfd_XXi_swap_aouthdr_in, _bfd_XXi_swap_aouthdr_out, _bfd_XXi_swap_scnhdr_out, pe_print_pdata, _bfd_XX_print_private_bfd_data_common, _bfd_XX_bfd_copy_private_section_data, _bfd_XXi_final_link_postscript): Support COFF_WITH_peLoongArch64, * pei-loongarch64.c: New file. * peicode.h (coff_swap_scnhdr_in, pe_ILF_build_a_bfd, pe_ILF_object_p): Support COFF_WITH_peLoongArch64.

Alan Modra	1a5178fe28	PR29348, BFD_VMA_FMT wrong There is a problem with my commit `0e3c1eebb2`, which replaced bfd_uint64_t with uint64_t: Some hosts typedef int64_t to long long even when long is the same size as long long. That confuses the code choosing one of "l", "ll", or "I64" for BFD_VMA_FMT, and results in warnings. Write a direct configure test for the printf int64_t style instead.

Alan Modra	6015985895	Replace bfd_hostptr_t with uintptr_t bfd_hostptr_t is defined as a type large enough to hold either a long or a pointer. It mostly appears in the coff backend code in casts. include/coff/internal.h struct internal_syment and union internal_auxent have the only uses in data structures, where comparison with include/coff/external.h and other code reveals that the type only needs to be large enough for a 32-bit integer or a pointer.

Simon Marchi	978602e83f	bfd: add AMDGCN architecture Add support for the AMDGCN architecture to BFD. This is the bare minimum to get $ ./configure --target=amdgcn-hsa-amdhsa --disable-gas $ make all-binutils working later in this series. The specific AMDGCN models added here are a bit arbitrary, based on what we intend to initially support in GDB. This list will need to be updated in the future anyway. The complete up-to-date list of existing AMDGPU models can be found here: https://llvm.org/docs/AMDGPUUsage.html#processors The ELF format for this architecture is documented here: https://llvm.org/docs/AMDGPUUsage.html#elf-code-object The flags for the "HSA" OS ABI are properly versioned and documented on that page. But the NONE, PAL and MESA3D OS ABIs are not well documented nor versioned. Taking a peek at the LLVM source code, we see that they encode their flags the same way as HSA v3. For example, for PAL: `c8b614cd74/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp (L601)` So at least, we know that all AMDGPU objects (of which AMDGCN objects are a subset of) at the time of writing encode the specific GPU model in the EF_AMDGPU_MACH field of e_flags. bfd/ChangeLog: * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add cpu-amdgcn.c.
