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.
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.
We don't want arch-specific entries in the common ChangeLog files.
Most arches do this already, so clean up the recent additions, and
move some older entries down to help avoid confusing newcomers.
PR ld/13900
Linking this test crashes the linker, so disable it. The crash
was reported about 9 years ago but haven't made progress, so lets
avoid the failures in test runs.
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.
Make sure we include unistd.h for getpid prototypes to fix build
warnings/errors with newer compilers & C libraries.
Doing that for close in openpf highlights these were using the
wrong function -- need to use fclose on FILE*, not close.
These tests pass again with a cris-elf toolchain.
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.
These tests all fail to assemble when targeting the h8300 or h8300h
cpu variants with errors like:
rotl.s:242: Warning: Opcode `rotl.b' with these operand types not available in H8/300H mode
rotl.s:242: Error: invalid operands
It's been this way for years and no one seems to care, so disable
them for those targets since the assembler thinks it's impossible.
We don't need to manually enumerate every test. Use a glob function
like every other port and rely on the (already existing) #mach headers
in each file to filter out targets we don't care about.
Make sure the files using abs() include stdlib.h for its prototype.
These files were relying on it being included implicitly by others
which isn't guaranteed, and newer toolchains produce warnings.

Binutils support for LMBD instruction was merged [1]. So add it also
to simulator.
LMBD instruction does left-most-bit-detection. It returns 32 if
the given bit value is not found in the provided word value.

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.

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.

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:

No other sub directory provides such a configuration option, so
drop it from the sim dir as well. This cleans up a good bit of
code in the process.
If people want to use custom flags for just the sim, they can
still run configure+make by hand in the sim subdir and use the
normal CFLAGS settings.
The cris sim hit a few failures after the recent getopt logic, and the
expected output showed a few ways we can improve things to better match
other utils.
Rather than re-invent endian defines, as well as maintain our own list
of OS & arch-specific includes, punt all that logic in favor of the bfd
ones already set up and maintained elsewhere. We already rely on the
bfd library, so leveraging the endian aspect should be fine.
The cris port was using the device framework to handle two addresses when
the --cris-900000xx flag was specified. That can be implemented using the
newer hardware framework instead which allows us to drop the device logic
entirely, as well as delete the tconfig.h file. Basically we create a new
cris_900000xx device model and move the read logic out of devices.c and
into that. The rest of the devices logic was callback to the hardware
framework already.
Much like we autodetect the path to the run program when there is none
set explicitly, do the same for the rvdummy program. Otherwise the
default make check fails to execute the helper properly.
Most targets already default to loading code via their LMA, but for
a few, this means the default changes from loading VMA to LMA. It's
better to have the different targets be consistent, and allows some
code clean up.
Sometimes in tests, we need supplemental files like linker scripts or
board helper files. There's no way to set those flags in the tests
currently and relative paths don't work (breaks out of tree builds).
Update the main option parser to replace some strings on the fly. Now
tests can do things like:
Long term we'll want to switch the framework to use the dejagnu helpers
like dg-xxx that gcc & gdb utilize. But that'll require more rework.
When handling left saturated ashifts with negative immediates, they
should be treated as right ashifts. This matches hardware behavior.

(writemsg): Moved the la and li instructions before the data they are

of micromips relocations when building for micromips.
The nrun conversion was slightly incorrect in how it stopped when an
exception occurred. We still set cpu.asregs.exception, but nothing
was checking it anymore. Convert all of that to sim_engine_halt.
To keep things from regressing again, add a basic testsuite too.
A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point. But at least this
is an improvement on the status quo.
Looks like historical restructuring in this dir lost the d10v-elf subdir
and no one noticed in the meantime. Re-add it to the testsuite.
There are some failures, but better some tests get run than none at all.
Since the sim doesn't have any debug support in it, we can only exit
cleanly. But this is still better than nothing.
Change the default microblaze sim to not dump the debug load output
when running. No other does this, and it breaks the testsuite.
If a test doesn't write anything at all to stdout, the current test
framework can't support that. Even if you put a blank output line:
# output:
the setup happily clobbers that with a default pass/fail string.
Tweak the parsing logic so we only set the output to pass/fail when
the test has no output marker.
Since the testsuite subdir has to handle dynamic arch values already,
there's no real value in requiring arches to opt in to it. Most have
a testsuite now anyways, and we're requiring it in the future.
I meant for this script to be +x, but missed when doing the initial CVS
commit. It wasn't possible to fix w/CVS, but it is w/git, so do it.

* run-tests.sh: Add +x file mode.
Since the sim has a few fake debug insns that the hardware does not, we
need to check for those before attempting to run them. Otherwise we'll
randomly trigger the sim debug asserts/aborts/halts insns. On the
hardware, these are proper invalid insns, and the table catches that.
The main body of the "all insn" test is executed once per tested insn, and
we test millions of insns here. Any shrinkage we can do in this loop will
speed things up nicely (since it's multiplied per tested insn).
To that end, simplify the end-of-table test into one less insn, and omit
the SSYNC when we build for the sim. When we build to run on the hardware,
this insn matters, but the sim doesn't have write store buffers in the chip
that might get in the way (memory writes are atomic).
Since these insns run in usermode, there should be no need to setup
RET[ENI] to safe values. They won't be dereferenced, and any insn
that returns via them are valid only in supervisor mode. Since this
is in the main exception code path, saving any insn at all is good
as it gets multiplied quickly (as in O(n^2) times).
