The fix H.J. implemented for PR gas/22791 in the thread starting at [PATCH] x86-64: Treat PC32 relocation with branch as PLT32 https://sourceware.org/ml/binutils/2018-02/msg00065.html is causing problems on Solaris/x86. The native linker is strongly preferred there, and there's no intention of implementing the linker optimization he plans there. Besides, the kernel runtime linker, otherwise has no need to deal with that reloc at all, and instead of adding (possibly even more) workarounds with no benefit, it seems appropriate to disable the R_X86_64_PLT32 generation as branch marker on Solaris/x86 in the first place. The patch itself is trivial, the only complication is adapting the testsuite. Since I've found no way to have conditional sections in the .d files, I've instead used the solution already found elsewhere of having separate .d files for the affected tests in an i386/solaris subdirectory and skipping the original ones. Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu without regressions. * config/tc-i386.c (need_plt32_p) [TE_SOLARIS]: Return FALSE. * testsuite/gas/i386/solaris/solaris.exp: New driver. * testsuite/gas/i386/solaris/reloc64.d, testsuite/gas/i386/solaris/x86-64-jump.d, testsuite/gas/i386/solaris/x86-64-mpx-branch-1.d, testsuite/gas/i386/solaris/x86-64-mpx-branch-2.d, testsuite/gas/i386/solaris/x86-64-nop-3.d, testsuite/gas/i386/solaris/x86-64-nop-4.d, testsuite/gas/i386/solaris/x86-64-nop-5.d, testsuite/gas/i386/solaris/x86-64-relax-2.d, testsuite/gas/i386/solaris/x86-64-relax-3.d: New tests. * testsuite/gas/i386/reloc64.d, testsuite/gas/i386/x86-64-jump.d, testsuite/gas/i386/x86-64-mpx-branch-1.d, testsuite/gas/i386/x86-64-mpx-branch-2.d, testsuite/gas/i386/x86-64-nop-3.d, testsuite/gas/i386/x86-64-nop-4.d, testsuite/gas/i386/x86-64-nop-5.d, testsuite/gas/i386/x86-64-relax-2.d, testsuite/gas/i386/x86-64-relax-3.d: Skip on *-*-solaris*. |

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.
