Avoid scan of symbols on objects in coff archives since we don't need to do anything special with common symbols. The scan is quite useless, and breaks LTO due to slim LTO objects not having symbols available until after the plugin has claimed them. Instead we can add objects based on their archive symbol map. Also, rip out the archive symbol hash table used by the generic linker. Using a hash breaks one feature of unix archive linking; The first object file in an archive defining any given symbol should be the object extracted to satisfy that symbol. What's more a hash isn't much faster except in pathological cases where object file ordering causes many scans of the archive. See the comment which I'm removing from elf_link_add_archive_symbols. Finally, tidy elflink.c archive handling a little. PR 13557 * linker.c (struct archive_list, struct archive_hash_entry, struct archive_hash_table, archive_hash_newfunc, archive_hash_table_init, archive_hash_lookup, archive_hash_allocate, archive_hash_table_free): Delete. (_bfd_generic_link_add_archive_symbols): Add h and name params to checkfn. Rewrite using a straight-forward scan over archive map. (generic_link_check_archive_element_no_collect, generic_link_check_archive_element_collect, generic_link_check_archive_element): Add h and name params. * aoutx.h (aout_link_check_archive_element): Likewise. * pdp11.c (aout_link_check_archive_element): Likewise. * xcofflink.c (xcoff_link_check_archive_element): Likewise. * cofflink.c (coff_link_check_archive_element): Likewise. Don't scan symbols, simply add archive element whenever h is undefined. (coff_link_check_ar_symbols): Delete. * ecoff.c (read_ext_syms_and_strs): Delete. (reread_ext_syms_and_strs): Delete. (ecoff_link_check_archive_element): Add h and name param. Don't scan symbols, simply add based on h. Use ecoff_link_add_object_symbols. * elflink.c (elf_link_is_defined_archive_symbol): Don't test archive_pass. (elf_link_add_archive_symbols): Delete "defined" array, merge functionality into "included". Make "included" a char array. Don't set or test archive_pass. * libbfd-in.h (_bfd_generic_link_add_archive_symbols): Update. * libbfd.h: Regenerate. |

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.
