This adds a --no-tls-optimize option for people who want to keep __tls_get_addr calls in an executable rather than optimizing such code sequences to IE/LE. Also tidy some formatting errors, rename a variable to better reflect its use, and tweak two functions that create pairs of GOT entries to first check whether the GOT entry already exists before potentially inserting the header via reserve(2). Without the check it is possible to waste one GOT entry. * options.h (no_tls_optimize): New powerpc option. * powerpc.cc (Target_powerpc::abiversion, set_abiversion): Formatting. (Target_powerpc::stk_toc): Formatting, fix comment. (Target_powerpc::Track_tls::tls_get_addr_state): Rename from tls_get_addr. (Target_powerpc::optimize_tls_gd, optimize_tls_ld, optimize_tls_ie): Return TLSOPT_NONE when !tls_optimize. (Target_powerpc::add_global_pair_with_rel): Check for existing reloc before reserving. (Target_powerpc::add_local_tls_pair): Likewise.
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.
