Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.

* syscalls.c: Likewise.
* trace.c: Likewise.
* interp.c: Include config.h before system header files.
The common code has a sim_core_trans_addr() helper that only the m32r code
uses. Move the inline extern in the m32r code to the proper common header.

Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.

The sim code gets the logic for SIM_AC_OPTION_WARNINGS from gdb, but
it hasn't been updated in a good long while. Sync with the latest
gdb code.
There is a sim specific change in here: we disable -Werror for now.
This is because all sim code atm contains warnings. Will probably
have to slowly add a white list of targets which can tolerate this
until everyone is updated.

This isn't entirely correct in that it assumes the signal numbering of
the target and host match, but seeing as we already make that assumption
in a few places, this patch doesn't make the situation any worse.

Trying to run `headers` in an out-of-tree build fails atm due to the
relative srcdir paths being used in a location other than where they
were setup to be used from. Get abs_srcdir from configure and use
that instead where applicable.

Building the sim on a sparc-solaris 2.8 machine fails when configured
with no extra sim hardware:
> for hw in ; do \
> echo "extern const struct hw_descriptor
> dv_${hw}_descriptor[];" ; \
> done >> tmp-hw.h
> echo 'const char version[] = "'"`sed q
> /[...]/../../gdb/version.in`"'";'
> >> version.c-tmp
> /bin/sh: -c: line 1: syntax error near unexpected token `;'
> /bin/sh: -c: line 1: `for hw in ; do \'
> make[3]: *** [hw-config.h] Error 2
The same thing happens with the version of bash that we got from
Sun as well (which is very old: 2.03.0(1)-release).
The problems comes from the fact that both shells are buggy, and
reject the following script:
for hw in ; do
[...]
done
The above is what sim/common/Makefile.in tries to execute when
generating hw-config.h.
In order to allow users to build out of the box on these machines,
this patch works around this bug. It does rely on the fact that
none of the tokens in SIM_HW contain whitespaces.
sim/common/ChangeLog:
* Make-common.in (hw-config.h): Work around bug in Solaris 2.8
system bourne shell.
The common sim code provides a useful "get_string" function which reads
a C string out of the target's memory space. So rename and export it
for other people to use.

Lift the code that GDB is using to generate dependencies on the fly and
port it over to the sim. Now people shouldn't have to manually maintain
these in their Makefile's.

Some systems (like OS X) do not have posix_fallocate. Add a configure
check for it before we try to use it. This is less work than trying
to support old systems.

Automake likes to dump macros automatically used into the aclocal.m4
file, but the common/aclocal.m4 naming prevents that. So rename it
to the more normal "acinclude.m4" so the aclocal tool can work.

Now that the sourceware tree generally requires autoconf-2.64, update
the sim tree to require that too.
This allows us to drop the long standing SIM_AC_COMMON/common.m4
workaround as autoconf 2.64+ seems to work for me.

The dv-cfi code uses the bool type but doesn't include the stdbool.h
header. I didn't notice for Blackfin targets as the core Blackfin
header will include stdbool.h, but most targets don't do this.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
The "devices.h" header is Blackfin-specific, so trying to build dv-cfi
for any other target fails. Include the specific hw headers this file
needs directly.

The sim_args_command prototype is in sim-options.h, so pull it in
directly rather than assuming a common header does it.

Shell code before AC_INIT will be silently culled, and since the common
aclocal.m4 includes inline shell code, the file cannot be included before
AC_INIT. So update the example to show people including the file after
that rather than before to avoid random breakage.

The autoconf guys point out that our usage of AC_PROG_CC in the
SIM_AC_COMMON does not jive with their intended use.

So utilize AC_REQUIRE to make the warnings go away and generate
the correct code with different autoconf versions.

Since sim_do_command for many people simply calls sim_args_command, start
a unified version of it. For people who handle their own options, they
could switch to this by using sim_add_option_table instead.

The current --sysroot parsing attempts to keep from leaking memory by
treating the empty string specially (sine this is the initial value),
but it ends up leaking memory when the arg is an empty string. So if
someone uses --sysroot "", the old value is leaked, as is the new one.

A semi-recent change which regenerated nltvals.def somehow missed all of

It's useful to be able to trace just the system calls the simulated
program is calling, so add a new --trace-syscall option for ports to
leverage if they choose.

Some Blackfin parts tie a bunch of interrupt lines into a single OR
gate before feeding the result into the SIC. The glue-or device in
the sim provides a nice way of modeling this exact behavior. At the
moment though, it requires the device to be mapped into the address
space so that things could write to it directly. This is not needed
for the Blackfin usage, so make it optional. Now the glue devices
can be used to simply tie interrupt lines together.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
The glue device has a bunch of "todos" for the misc bitwise devices.
So implement two for fun -- the glue-or and glue-xor.

For now, only the sub-command name is completed. No support yet for
completing options to that command. But even this is a huge step as
currently, nothing is completed, and the basic "help sim" is fairly
obtuse as to what exactly the "sim" command accepts.

This simulates a CFI flash. Its pretty configurable via the device
tree. For now, only basic read/write/erase operations are supported
for the Intel command set, but it's easy enough to extend support.
It's certainly enough to trick Das U-Boot into using it for probing,
reading, writing, and erasing.

This can boot Das U-Boot and a Linux kernel. It also supports Linux
userspace FLAT and FDPIC (dynamic and static) ELFs.
