05385fc777 sim: testsuite: support exit 77 for unsupported tests
Exit status 77 is common (including the autotools world) to indicate
"skip this test".  Add support for mapping that to "unsupported" as
that's the closest in the dejagnu world.

1bcee7fd87 sim: testsuite: skip tests when the port is disabled
If the port hasn't been enabled, don't try to run its tests.  Making
this dynamic simplifies the test harnesses and avoids duplicating a
bunch of target tuple checks.

23cb7bac66 sim: testsuite: calculate $arch from $subdir
Since we require ports to use a matching subdir name in the testsuite
tree, we can use that to calculate the $arch value.

26da232cbd sim: example-synacor: a simple implementation for reference
Provide a simple example simulator for people porting to new targets
to use as a reference.  This one has the advantage of being used by
people and having a fun program available for it.

It doesn't require a special target -- the example simulators can be
built for any existing port.

b0dcd7d832 sim: testsuite: push $arch out to targets
This is needed to move to automake & its dejagnu-provided logic,
and eventually by the unified sim logic.  The $arch is used only
to figure out which `run` program to use when running tests, and
as we move to a single top-level build, we can delete this and
use sim/run directly.

b9249c461c sim: riscv: new port
This is a hand-written implementation that should have fairly complete
coverage for the base integer instruction set ("i"), and for the atomic
("a") and integer multiplication+division ("m") extensions.  It also
covers 32-bit & 64-bit targets.

The unittest coverage is a bit weak atm, but should get better.

1368b914e9 sim: testsuite: flatten tree
Now that all port tests live under testsuite/sim/*/, and none live
in testsuite/ directly, flatten the structure by moving all of the
dirs under testsuite/sim/ to testsuite/ directly.

We need to stop passing --tool to dejagnu so that it searches all
dirs and not just ones that start with "sim".  Since we have no
other dirs in this tree, and no plans to add any, should be fine.

bb3eddb5bd sim: testsuite: delete configure script
Now that we've moved all ports to dejagnu & testsuite/sim/, the only
thing the testsuite/configure script has been doing is filling in the
sim_arch field in the testsuite/Makefile.  We can simply let the top
sim/configure script do that for us now.  This simplifies & speeds up
the build a bit by killing an entire configure script.

29fd199ed8 sim: d10v: relocate tests & clean up test harness
This is the only target using a dir directly under testsuite/.  All
others use sim/<arch>/ instead.  Relocate it so all targets look the
same, and so we can leverage the common test harness.

We drop loop.s in the process because it was never referenced and
was just 2 lines of code.

All other test files are moved & have directives added to the top so
that the test harness can invoke them correctly.

137d6efd8a sim: mips: delete empty stub test dir
No tests were ever added in here in the ~22 years since it was first
created.  Seems unlikely any tests will be added at this rate, and
the sim/mips/ testdir already has some (light) coverage for this
target.  So punt the tree.

89bfc2a429 sim: frv: clean up redundant test coverage
The frv-elf subdir contained five tests:
* cache: A cache test of some sort.
* exit47: A program to test exit status of 47 from sim.
* grloop: Some basic limited loop test program.
* hello: Standard "hello world" output program.
* loop: An infinite loop program.

The loop.s test is never referenced anywhere, and is all of 2 lines.
Anyone who really needs a while(1); test case and re-implement it
themselves locally.

The cache.s code isn't referenced anywhere because it requires some
custom args to the run program, and when this testcase was added, we
didn't have any support for that.  We do now, so we can add a header
to enable that.  Turns out the code crashes even with those, so turn
around and mark it xfail.  Maybe someone someday will care.

That leaves the small exit47, grloop, and hello tests.  Now that the
sim test harness supports testing for custom exit status, we can move
them all to sim/frv/ to maintain test coverage.

The remaining differences between frv-elf & sim/frv are:
* frv-elf/ runs for frv-*-elf while sim/frv/ runs for frv*-*-*.
* frv-elf/ runs "*.s" files while sim/frv/ only has .cgs and such.

On closer inspection, these are also meaningless distinctions:
* There is nothing specific to the tests that require an *-elf
  target.  Normally that would mean newlib+libgloss type stuff,
  but there's no such requirement in frv-elf/.
* The ".s" suffix is the standard "this is an assembly file" suffix.
  Since FRV is a CGEN target, we can reuse the existing convention of
  ".ms" to mean "miscellaneous .s" as in "this is an assembly file,
  and run/bucket its test results in the miscellaneous category".

So moving frv-elf/{cache,exit47,grloop,hello}.s to sim/frv/*.ms makes
sense and simplifies things quite a bit for the target while also
slightly increasing the coverage for some tuples.

7cf91a2481 sim: m32r: clean up redundant test coverage
The m32r-elf subdir contained three tests:
* exit47: A program to test exit status of 47 from sim.
* hello: Standard "hello world" output program.
* loop: An infinite loop program.

There's already a sim/m32r/hello.ms test that does exactly the same
thing as m32r-elf/hello.s, so we can delete that.

The loop.s test is never referenced anywhere, and is all of 2 lines.
Anyone who really needs a while(1); test case and re-implement it
themselves locally.

That leaves the single exit47 test.  Now that the sim test harness
supports testing for custom exit status, we can easily move that to
sim/m32r/exit47.ms to maintain test coverage.

The remaining differences between m32r-elf & sim/m32r are:
* m32r-elf/ runs for m32r-*-elf while sim/m32r/ runs for m32r*-*-*.
* m32r-elf/ runs "*.s" files while sim/m32r/ runs "*.ms" files.

On closer inspection, these are also meaningless distinctions:
* There is nothing specific to the tests that require an *-elf
  target.  Normally that would mean newlib+libgloss type stuff,
  but there's no such requirement in m32r-elf/.
* The ".s" suffix is the standard "this is an assembly file"
  suffix.  Turns out ".ms" is just how sim/m32r/ (and a few other
  CGEN based targets) categorize/bucket test cases.  It simply
  means "miscellaneous .s" as in "this is an assembly file, and
  run/bucket its test results in the miscellaneous category".

So moving m32r-elf/exit47.s to sim/m32r/exit47.ms makes sense and
simplifies things quite a bit for the target while also slightly
increasing the coverage for some tuples.

37a9c3a53e sim: testsuite: allow tests to declare expected exit status
Some tests want to verify they can control the exit status, and
allowing any non-zero value would allow tests to silently fail:
if it crashed & exited 1, or forced all non-zero to 1, then we
wouldn't be able to differentiate with a test exiting with a
status like 47.

Extend the test harness to allow tests to declare their expected
exit status that would be defined as a "pass".  This requires a
small tweak to the sim_run API to return the status directly, but
that shouldn't be a big deal as it's only used by sim code.

254c3783fe sim: tests: get common tests working again
These were written with 32-bit host assumptions baked into it.
Simplify the printf formats to use ll length modifier as it's
in C11 rather than trying to manually break it up into two,
and cleanup some of the casts to stop assuming sizeof(long) is
the same as sizeof(int).

We also have to add a few more includes for the various funcs
used in here.

The tests aren't compiled automatically still.  We can figure
that out later with more work.

a39487c668 sim: cris: use -sim with C tests for cris-elf targets
Building the C tests with a cris-elf toolchain (gcc-10.2 &
newlib-4.1.0) currently fail due to warnings it emits:
cris-elf-ld: libc.a(lib_a-closer.o): in function `_close_r':
newlib/libc/reent/closer.c:47: warning: _close is not implemented and will always fail

This is because the default target for cris-elf is bare metal, not
the simulator.  For that, we need -sim.  So add it for elf targets.

We don't add it for all targets as the simulator (and testsuite)
run both libgloss programs as well as Linux userspace programs.

865288236d sim: fr30: delete unused testsuite
Looking through the history, it doesn't seem like the fr30 port was
ever merged.  There used to be a testsuite/fr30-elf/ dir, but that
was punted back in 2005 as being dead too.  Since there's no refs
and the dir hasn't been touched since 1999, lets assume no one will
ever notice or care.

043f5c63f0 sim: Fix autoreconf errors in sim/ directory
Run autoreconf in sim/ directory and you'll see some errors.  The
problem is that autoreconf (a perl script) does not evaluate the value
passed as an argument to AC_CONFIG_AUX_DIR, so something like:

  AC_CONFIG_AUX_DIR(`cd $srcdir;pwd`/../..)

does not do the right thing inside autoreconf, my understanding is
that changing to something like this is fine:

  AC_CONFIG_AUX_DIR(../..)

the generated configure seems to check the value passed, and the value
passed relative to the source directory, so I think we get basically
the same behaviour as before.

e8a387fb5f MSP430: sim: Fix incorrect simulation of unsigned widening multiply
Operand sizes used for simulation of MSP430 hardware multiply
operations are not aligned with the sizes used on the target, resulting
in the simulator storing signed operands with too much precision.

Additionally, simulation of unsigned multiplication is missing explicit
casts to prevent any implicit sign extension.

gcc.c-torture/execute/pr91450-1.c uses unsigned widening multiplication
of 32-bit operands -4 and 2, to produce a 64-bit result:
0xffff fffc * 0x2 = 0x1 ffff fff8

If -4 is stored in 64-bit precision, then the multiplication is
essentially signed and the result is -8 in 64-bit precision
(0xffff ffff ffff fffc), which is not correct.

sim/msp430/ChangeLog:

	* msp430-sim.c (put_op): For unsigned multiplication, explicitly cast
	operands to the unsigned type before multiplying.

	operands.

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.

gdb/ChangeLog:

	Update copyright year range in all GDB files.

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...
  /usr/share/aclocal/threadlib.m4:29: gl_THREADLIB_EARLY is expanded from...

  /usr/share/aclocal/gettext.m4:57: AM_GNU_GETTEXT is expanded from...
  configure.ac:7: the top level

Solution 10:

  Add AC_USE_SYSTEM_EXTENSIONS in configure.ac.
