With this patch dedicated linker scripts can be generated for partial relro triggered by defining GENERATE_RELRO_SCRIPT in the target specific scripts. This is necessary for e.g. S/390 where usually the .got.plt comes first and prevents the relro segment from being extended across the non-plt GOT entries. The patch started with the work from Marcin taken from the mwk user branches. However, the patch needed substantial changes due to the 'separate code' feature which got committed in the meantime. ld/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> Marcin Kościelnicki <koriakin@0x04.net> * emultempl/elf32.em: Add code to pick dedicated linker scripts for partial relro. * genscripts.sh: Generate dedicated linker scripts for partial relro.

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.
