4df817de57 sim: mips: fix qh_acc table
The AccAddLQH func was unused, and looking at this table, it looks
like it's due to a typo.

aa0fca163e sim: add support for build-time ar & ranlib
This is needed when building for a target whose ar & ranlib are
incompatible with the current build system.  For example, building
for Windows on a Linux system.

Then manually import the automake rule for libigen.a, but tweak the
tool variables to use the FOR_BUILD variants.

fe34861780 sim: nrun: add local strsignal prototype
While libiberty provides a definition for this for systems that lack
the function (e.g. Windows), it doesn't provide a prototype.  So add
our own local copy in the one file that uses the func.

9d90335212 sim: simplify hardware m4 macro
Every port using this sets the 1st arg to yes and the 2nd arg to "".
These are the defaults we probably want anyways in order to unify the
codebase, so move them to the macro and only allow ports to declare
extra hardware models.

19f6a43c6c Do not check for sys/time.h or sys/times.h
This updates the sim so that it unconditionally uses sys/time.h.  This
is in agreement with existing code, and a recent change to BFD.

I also think that sys/times.h is never needed by the sim, so this
patch removes the check and the one spot that was conditionally
including it.

e7d8f1da71 Remove and modernize dependencies in sim
Some spots in the sim build used manual dependencies, and some spots
did a compilation by hand but did not use the automatic dependency
tracking code.  This patch fixes these spots.

I didn't touch ppc, because it doesn't use the common Makefile code.
I also didn't touch objects that are for the build machine, because
automatic dependencies don't work for those.

1f195bc327 sim: use -Werror when probing for supported warning flags
When building with clang, we get:

    error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option]

This is because clang only warns by default when encountering an unknown
warning option, and the probe for supported warning flags is done
without -Werror.  All flags are therefore accepted by configure, but
then it breaks when actually compiling a source file with -Werror.

This is equivalent to this commit in gdb:

    3e019bdc20
    gdb: Use -Werror when checking for (un)supported warning flags

We then see some other compilation errors when building with clang and
-Werror, they can be dealt with later.

2b8d134be4 sim: set ASAN_OPTIONS=detect_leaks=0 when running igen and opc2c
The igen/dgen and opc2c tools leak their heap-allocated memory (on
purpose) at program exit, which makes AddressSanitizer fail the tool
execution.  This breaks the build, as it makes the tool return a
non-zero exit code.

Fix that by disabling leak detection through the setting of that
environment variable.

I also changed the opc2c rules for m32c to go through a temporary file.
What happened is that the failing opc2c would produce an incomplete file
(probably because ASan exits the process before stdout is flushed).
This meant that further make attempts didn't try to re-create the file,
as it already existed.  A "clean" was therefore necessary.  This can
also happen in regular builds if the user interrupts the build (^C) in
the middle of the opc2c execution and tries to resume it.  Going to a
temporary file avoids this issue.

the sim_pc_get API so this module works for all ports, and then we can
delete this old back channel of snooping in the port's cpu state -- the
code needs the pointer to the pc storage so that it can read out bytes
and compare them to the watchrange.

This also fixes the logic on multi-cpu sims by removing the limitation
of only being able to watch CPU0's state.

7a36eeea26 sim: common: switch AC_CONFIG_HEADERS
The AC_CONFIG_HEADER macro is long deprecated, so switch to the
newer form.  This also gets rid of the position limitation, and
drops support for an argument to SIM_AC_COMMON which we haven't
used anywhere.

aa09469fc6 sim: drop use of bfd/configure.host
These settings might have made sense in darker compiler times, but I
think they're largely obsolete now.  Looking through the values that
get used in HDEFINES, it's quite limited, and configure itself should
handle them.  If we still need something, we can leverage standard
autoconf macros instead, after we get a clear user report.

TDEFINES was never set anywhere and was always empty, so prune that.

d4e3adda12 sim: watchpoints: change sizeof_pc to sizeof(sim_cia)
Existing ports already have sizeof_pc set to the same size as sim_cia,
so simply make that part of the core code.  We already assume this in
places by way of sim_pc_{get,set}, and this is how it's documented in
the sim-base.h API.

There is code to allow sims to pick different register word sizes from
address sizes, but most ports use the defaults for both (32-bits), and
the few that support multiple register sizes never change the address
size (so address defaults to register).  I can't think of any machine
where the register hardware size would be larger than the address word
size either.  We have ABIs that behave that way (e.g. x32), but the
hardware is still equivalent register sized.

68ed285428 sim: clean up C11 header includes
Since we require C11 now, we can assume many headers exist, and
clean up all of the conditional includes.  It's not like any of
this code actually accounted for the headers not existing, just
whether we could include them.

The strings.h cleanup is a little nuanced: it isn't in C11, but
every use of it in the codebase will include strings.h only if
string.h doesn't exist.  Since we now assume the C11 string.h
exists, we'll never include strings.h, so we can delete it.

bf470982f9 sim: enable -Werror by default for some arches
We've had this off for a long time because the sim code was way too
full of warnings for it to be feasible.  However, I've cleaned things
up significantly from when this was first merged, and we can start to
turn this around.

Change the macro to enable -Werror by default, and allow ports to opt
out.  New ports will get it automatically (and we can push back on
them if they try to turn it off).

Also turn it off for the few ports that still hit warnings for me.
All the rest will get the new default, and we'll wait for feedback
if/when new issues come up.

46f900c065 sim: require a C11 compiler
With GDB requiring a C++11 compiler now, this hopefully shouldn't
be a big deal.  It's been 10 years since C11 came out, so should
be plenty of time to upgrade.

This will allow us to start cleaning up random header logic and
many of our non-standard custom types.

42a4f53d2b Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

d0ac1c4488 Bump to autoconf 2.69 and automake 1.15.1
When trying to run the update-gnulib.sh script in gdb, I get this:

Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^      =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.

Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22.  It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import.  And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.

For autoconf, the 2.69 version is universally available, so it's an easy
choice.  For automake, different distros and distro versions have
different automake versions.  But 1.15.1 seems to be the most readily
available as a package.  In any case, it's easy to build it from source.

I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case.  They only specify a
lower bound for the acceptable version of automake/autoconf.  That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version).  In our case, we force people to use a
specific version anyway.  For the autoconf version, we have the check in
config/override.m4 that enforces the version we want.  It will be one
less thing to update next time we change autotools version.

I hit a few categories of problems that required some changes.  They are
described below along with the chosen solutions.

Problem 1:

  configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.  For more info, see:
  configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation

Solution 1:

  Adjust the code based on the example at that URL.

Problem 2 (in zlib/):

  Makefile.am: error: required file './INSTALL' not found
  Makefile.am:   'automake --add-missing' can install 'INSTALL'
  Makefile.am: error: required file './NEWS' not found
  Makefile.am: error: required file './AUTHORS' not found
  Makefile.am: error: required file './COPYING' not found
  Makefile.am:   'automake --add-missing' can install 'COPYING'

Solution 2:

  Add the foreign option to AUTOMAKE_OPTIONS.

Problem 3:

  doc/Makefile.am:20: error: support for Cygnus-style trees has been removed

Solution 3:

  Remove the cygnus options.

Problem 4:

  Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')

Solution 4:

  Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
  already defined earlier).

Problem 5:

  doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
  doc/Makefile.am: warning: Oops!
  doc/Makefile.am:     It appears this file (or files included by it) are triggering
  doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
  doc/Makefile.am:     Future automake versions will no longer place in the builddir
  doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
  doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
  doc/Makefile.am:     DISTCLEANFILES.
  doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
  doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
  doc/Makefile.am:     'info-in-builddir' automake option.

Solution 5:

  Rename .texinfo files to .texi.

Problem 6:

  doc/Makefile.am: warning: Oops!
  doc/Makefile.am:     It appears this file (or files included by it) are triggering
  doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
  doc/Makefile.am:     Future automake versions will no longer place in the builddir
  doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
  doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
  doc/Makefile.am:     DISTCLEANFILES.
  doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
  doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
  doc/Makefile.am:     'info-in-builddir' automake option.

Solution 6:

  Remove the hack at the bottom of doc/Makefile.am and use
  the info-in-builddir automake option.

Problem 7:

  doc/Makefile.am:35: error: required file '../texinfo.tex' not found
  doc/Makefile.am:35:   'automake --add-missing' can install 'texinfo.tex'

Solution 7:

  Use the no-texinfo.tex automake option.  We also have one in
  texinfo/texinfo.tex, not sure if we should point to that, or move it
  (or a newer version of it added with automake --add-missing) to
  top-level.

Problem 8:

  Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
  Makefile.am:131: but option 'subdir-objects' is disabled
  automake: warning: possible forward-incompatibility.
  automake: At least a source file is in a subdirectory, but the 'subdir-objects'
  automake: automake option hasn't been enabled.  For now, the corresponding output
  automake: object file(s) will be placed in the top-level directory.  However,
  automake: this behaviour will change in future Automake versions: they will
  automake: unconditionally cause object files to be placed in the same subdirectory
  automake: of the corresponding sources.
  automake: You are advised to start using 'subdir-objects' option throughout your
  automake: project, to avoid future incompatibilities.

Solution 8:

  Use subdir-objects, that means adjusting references to some .o that will now
  be in config/.

Problem 9:

  configure.ac:375: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body
  ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from...
  ../../lib/autoconf/general.m4:2601: _AC_COMPILE_IFELSE is expanded from...

  ../../lib/autoconf/general.m4:2063: AC_CACHE_CHECK is expanded from...
  configure.ac:375: the top level

Solution 9:

  Use AC_LANG_SOURCE, or use proper quoting.

Problem 10 (in intl/):

  configure.ac:7: warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
  /usr/share/aclocal/threadlib.m4:36: gl_THREADLIB_EARLY_BODY is expanded from...

91588b3af8 sim: mips: fix dv-tx3904cpu build error
When building for mipstx39-rtems4.12 targets, some funcs use SD and CPU
implicitly.  Restore the defines for these to the local sd and cpu vars.

This was broken by the clean up in commit d47f5b30d8.

1554f75841 sim: mips: fix prog_bfd usage
We do not want to reference the "base" member directly.  We have the
STATE_PROG_BFD macro instead to look up the prog_bfd member.

3d304f48ca MIPS: Only build microMIPS specific simulator functions if microMIPS support is required.
This fixes PR sim/19441.  In the MIPS simulator the microMIPS
functions in micromips.igen were not predicated on the microMIPS
models.  This was causing build issues for some target triples.
This patch sets all the microMIPS specific functions to only be built if
the micromips32, micromips64 or micromipsdsp models are used.

	PR sim/19441
	* micromips.igen (delayslot_micromips): Enable for `micromips32',
	`micromips64' and `micromipsdsp' only.
	(process_isa_mode): Enable for `micromips32' and `micromips64' only.

b36d953bce sim: mips: workaround 32-bit addr sign extensions
The mips bfd will sign extend 32-bit addresses into 64-bit values,
so if the entry happens to be 0x80000000 or higher, it is turned to
0xffffffff80000000 which points to memory that doesn't exist.

This wasn't an issue until commit 26f8bf63bf
as all addresses were automatically truncated there in the translate
function to 32-bits.  When we cleaned up that code, the full 64-bits
were checked leading to many test failures for mips-sde-elf targets
and such.

ce39bd3890 sim: move many common settings from CPPFLAGS to config.h
Rather than stuffing the command line with a bunch of -D flags, start
moving things to config.h which is managed by autoheader.  This makes
the makefile a bit simpler and the build output tighter, and it makes
the migration to automake easier as there are fewer vars to juggle.

We'll want to move the other options out too, but it'll take more work.
