Allow gdb to find debug symbols file by build-id for PE file format also This promotes BFD's struct elf_build_id to the generic struct bfd_build_id, populated when an ELF or PE BFD is read. gdb is updated to use that, and to use the build-id to find symbols for PE files also. There is currently no generic way to extract the build-id from an object file, perhaps an option to objdump to do this might make sense?

Delay setting up compressed debug section names When we set up st_name for output section name in elf_fake_sections, we don't know if the compressed DWARF debug section will be smaller. We may end up with compressed DWARF debug sections which are bigger than the uncompressed ones. This patch delays setting up st_name for output DWARF debug section to _bfd_elf_assign_file_positions_for_non_load which will compress the output debug section. We also postpone placement of shstrtab section after DWARF debug sections have been compressed. The net effect is .shstrtab section is now placed after .symtab and .strtab sections. bfd/ PR ld/18277 * compress.c (bfd_compress_section_contents): Remove the write_compress argument.

Add -z noextern-protected-data to ld for ELF/x86 Address of protected data defined in the shared library may be external, i.e., due to copy relocation. By default, linker backend checks if relocations against protected data symbols are valid for building shared library and issues an error if relocation isn't allowed. The new option override linker backend default. When -z noextern-protected-data is used, updates on protected data symbols by another module won't be visibile to the resulting shared library.

Add support for the x86 XSAVE extended state on FreeBSD/x86. Recognize NT_X86_XSTATE notes in FreeBSD process cores. Recent FreeBSD versions include a note containing the XSAVE state for each thread in the process when XSAVE is in use. The note stores a copy of the current XSAVE mask in a reserved section of the machine-defined XSAVE state at the same offset as Linux's NT_X86_XSTATE note. For native processes, use the PT_GETXSTATE_INFO ptrace request to determine if XSAVE is enabled, and if so the active XSAVE state mask (that is, the value of %xcr0 for the target process) as well as the size of XSAVE state area. Use the PT_GETXSTATE and PT_SETXSTATE requests to fetch and store the XSAVE state, respectively, in the BSD x86 native targets. In addition, the FreeBSD amd64 and i386 native targets now include "read_description" target methods to determine the correct x86 target description for the current XSAVE mask. On FreeBSD amd64 this also properly returns an i386 target description for 32-bit binaries which allows the 64-bit GDB to run 32-bit binaries. Note that the ptrace changes are in the BSD native targets, not the FreeBSD-specific native targets since that is where the other ptrace register accesses occur. Of the other BSDs, NetBSD and DragonFly use XSAVE in the kernel but do not currently export the extended state via ptrace(2). OpenBSD does not currently support XSAVE. bfd/ChangeLog: * elf.c (elfcore_grok_note): Recognize NT_X86_XSTATE on FreeBSD.

Tidy. Expand comment.
Properly place the NULL STT_FILE symbol revistited I was having a little closer look at what is going on here and noticed that HJ unconditionally emits a NULL STT_FILE symbol before emitting forced local symbols. That means we really don't need a second pass over forced local symbols. The only reason for two passes is when some forced local symbol can be emitted before the NULL STT_FILE. So I set about removing the second pass, updating the testsuite all over again. It's also unnecessary to emit the NULL STT_FILE when no previous file symbol has been emitted. bfd/ PR ld/17975 * elflink.c (struct elf_outext_info): Remove need_second_pass and second_pass.

PR ld/17973 LTO file syms LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

Fallout from recent bfd_reloc_outofrange changes Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..
