This implements padding of orphan executable sections for PowerPC. Of course, the simple implementation of bfd_arch_ppc_nop_fill and removing the NOP definition didn't work, with powerpc64 hitting a testsuite failure linking to S-records. That's because the srec target is BFD_ENDIAN_UNKNOWN so the test of bfd_big_endian (abfd) in default_data_link_order therefore returned false, resulting in a little-endian nop pattern. The rest of the patch fixes that problem by adding a new field to bfd_link_info that can be used to determine actual endianness on targets like srec. PR 13616 include/ * bfdlink.h (struct bfd_link_info <big_endian>): New field. bfd/ * cpu-powerpc.c (bfd_arch_ppc_nop_fill): New function, use it for all ppc arch info. * linker.c (default_data_link_order): Pass info->big_endian to arch_info->fill function. ld/ * emulparams/elf64lppc.sh (NOP): Don't define. * emulparams/elf64ppc.sh (NOP): Don't define. * ldwrite.c (build_link_order): Use link_info.big_endian.

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.
