This fixes two cases where elf_link_add_object_symbols returns an error, setting the catch-all bfd_error_bad_value without explaining the error. The second one is an internal error that can only be caused by a target elf_add_symbol_hook, so make that one abort. The first one is my PR24339 fix. PR24339 is another of those fuzzing bugs and the fix I made catches the problem when loading symbols, rather than when symbols are used in relocs. While ld is correct to reject the object file as not complying with the ELF standard, let's be a little more forgiving for dynamic objects. PR 24857 PR 24339 * elflink.c (elf_link_add_object_symbols): Report an informative error on finding local symbols with index equal or greater than symbol table sh_info. Correct comment. Allow such symbols in dynamic objects. Abort on NULL section for symbol.
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.
