This adds missing support for a power10 version of the __tls_get_addr call stub implementing DT_PPC64_OPT PPC64_OPT_TLS. Without this, power10 code using __tls_get_addr fails miserably at runtime unless the --no-tls-get-addr-optimize option is given. PR 26656 * elf64-ppc.c (plt_stub_size): Add "odd" param. Use it with size_power10_offset rather than calculating from start of stub. Add size for notoc tls_get_addr_opt stub. (plt_stub_pad): Add "odd" param, pass to plt_stub_size. (build_tls_get_addr_head, build_tls_get_addr_tail): New functions. (build_tls_get_addr_stub): Delete. (ppc_build_one_stub): Use a temp for htab->params->stub_bfd. Emit notoc tls_get_addr_opt stub. Move eh_frame code to suit. Adjust code to use bfd_tls_get_addr_head/tail in place of build_tls_get_addr_stub. (ppc_size_one_stub): Size notoc tls_get_addr_opt stub. Adjust plt_stub_size and plt_stub_pad calls. Correct "odd" when padding stub. Size eh_frame for notoc stub too. Correct lr_restore value. (ppc64_elf_relocate_section): Don't skip over first insn of notoc tls_get_addr_opt stub.
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.
