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. (bfd_plugin_close_file_descriptor): New function. (try_claim): Call bfd_plugin_close_file_descriptor. * plugin.h (bfd_plugin_close_file_descriptor): New. * bfd-in2.h: Regenerated. ld/ PR ld/28040 * plugin.c (plugin_input_file): Add ibfd. (release_plugin_file_descriptor): New function. (release_input_file): Call release_plugin_file_descriptor to close input->fd. (plugin_object_p): Call release_plugin_file_descriptor to close input->fd. Also call release_plugin_file_descriptor if not claimed. * testsuite/config/default.exp (RANLIB): New. * testsuite/ld-plugin/lto.exp: Run ranlib test. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
