/* Plugin support for BFD.
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.

Add LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [GCC PR109128] This is one part of the fix for GCC PR109128, along with a corresponding GCC change. Without this patch, what happens in the linker, when an unused object in a .a file has offload data, is that elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p, which ends up calling the plugin's claim_file_handler, which then records the object as one with offload data. That is, the linker never decides to use the object in the first place, but use of this _p interface (called as part of trying to decide whether to use the object) results in the plugin deciding to use its offload data (and a consequent mismatch in the offload data present at runtime). The new hook allows the linker plugin to distinguish calls to claim_file_handler that know the object is being used by the linker (from ldmain.c:add_archive_element), from calls that don't know it's being used by the linker (from elf_link_is_defined_archive_symbol); in the latter case, the plugin should avoid recording the object as one with offload data. bfd/ * plugin.c (struct plugin_list_entry): Add claim_file_v2.

void register_ld_plugin_object_p (bfd_cleanup (*object_p) (bfd *, bool));
ld: Cache and reuse the IR archive file descriptor Linker plugin_object_p opens the IR archive for each IR archive member. For GCC plugin, plugin_object_p closes the archive file descriptor. But for LLVM plugin, the archive file descriptor remains open. If there are 3000 IR archive members, there are 3000 file descriptors for them. We can run out of file descriptors petty easily. 1. Add archive_plugin_fd and archive_plugin_fd_open_count to bfd so that we can cache and reuse the IR archive file descriptor for all IR archive members in the archive. 2. Add bfd_plugin_close_file_descriptor to properly close the IR archive file descriptor. bfd/ PR ld/28040 * archive.c (_bfd_archive_close_and_cleanup): Close the archive plugin file descriptor if needed. * bfd.c (bfd): Add archive_plugin_fd and archive_plugin_fd_open_count. * opncls.c (_bfd_new_bfd): Initialize to -1. * plugin.c (bfd_plugin_open_input): Cache and reuse the archive plugin file descriptor.
