This patch fixes quite a lot of confusion in allocate_dynrelocs over ifuncs. Function descriptors make ELFv1 quite different to ELFv2. PR 20472 * elf64-ppc.c (ppc64_elf_before_check_relocs): Tweak abiversion test. (readonly_dynrelocs): Comment fix. (global_entry_stub): New function. (ppc64_elf_adjust_dynamic_symbol): Tweak abiversion test. Match ELFv2 code deciding on dynamic relocs vs. global entry stubs to that in size_global_entry_stubs, handling ifunc too. Delete dead weak sym code. (allocate_dynrelocs): Ensure dyn_relocs field is cleared when no dyn_relocs are needed. Correct handling of ifunc dyn_relocs. Tidy ELIMINATE_COPY_RELOCS code, only setting dynindx for undefweak syms. Expand and correct comments. (size_global_entry_stubs): Ensure symbol is defined. (ppc64_elf_relocate_section): Match condition under which dyn_relocs are emitted to that in allocate_dynrelocs.
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.
