Maciej W. Rozycki 72bc1bb934 ELF/BFD: Fix padding in `elf_external_linux_prpsinfo64'
Fix commit 70a38d42c5 ("New entry points for writing Linux NT_PRPSINFO
notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>,
and move the padding of the `elf_external_linux_prpsinfo64' structure to
match the corresponding 64-bit Linux kernel `elf_prpsinfo' structure.

The 64-bit kernel structure is defined as follows:

(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
    char pr_state;
    char pr_sname;
    char pr_zomb;
    char pr_nice;
    unsigned long pr_flag;
    __kernel_uid_t pr_uid;
    __kernel_gid_t pr_gid;
    pid_t pr_pid;
    pid_t pr_ppid;
    pid_t pr_pgrp;
    pid_t pr_sid;
    char pr_fname[16];
    char pr_psargs[80];
}
(gdb) print /x &((struct elf_prpsinfo *)0)->pr_nice
$1 = 0x3
(gdb) print /x &((struct elf_prpsinfo *)0)->pr_flag
$2 = 0x8
(gdb) print /x &((struct elf_prpsinfo *)0)->pr_uid
$3 = 0x10
(gdb) print sizeof(((struct elf_prpsinfo *)0)->pr_flag)
$4 = 8
(gdb)

with implicit padding present before the `pr_flag' member, to correctly
align it to a multiple of 8.  Conversely `elf_external_linux_prpsinfo64'
has padding after its `pr_flag' member:

(top-gdb) ptype struct elf_external_linux_prpsinfo64
type = struct elf_external_linux_prpsinfo64 {
    char pr_state;
    char pr_sname;
    char pr_zomb;
    char pr_nice;
    char pr_flag[8];
    char gap[4];
    char pr_uid[4];
    char pr_gid[4];
    char pr_pid[4];
    char pr_ppid[4];
    char pr_pgrp[4];
    char pr_sid[4];
    char pr_fname[16];
    char pr_psargs[80];
}
(top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_nice
$1 = 0x3
(top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_flag
$2 = 0x4
(top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_uid
$3 = 0x10
(top-gdb)

and consequently `pr_flag' is misplaced.  Move `gap' ahead of `pr_flag'
then.

	bfd/
	* elf-linux-core.h (elf_external_linux_prpsinfo64): Move the
	`gap' member ahead of `pr_flag'.

		   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.
