elf_gc_sweep_symbol should run after verdefs are calculated, since the verdef code creates symbols for the versions. However, elf_gc_sweep_symbol needs to run before verrefs so as to not emit useless verrefs for symbols that are gc'd. I've also removed a _bfd_elf_link_renumber_dynsyms calls added by Maciej after I fussed about it when reviewing. On further examination the call appears to be unnecessary. Looking at renumber_dynsyms also made me realize that the test to exclude .gnu.version has been wrong since 2016-04-26 (git commit d5486c4372), so fix that too. PR 22150 * elflink.c (bfd_elf_size_dynamic_sections): Garbage collect symbols before calculating verrefs. Don't renumber dynsyms after gc. Exclude .gnu.version when zero or one dynsym. Localize some vars and reindent.
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.
