Darwin's linker now warns when duplicate rpaths are presented - which
happens when we emit duplicate '-B' paths. In principle, we should avoid
this in the test-suite, however at present we tend to have duplicates
because different parts of the machinery add them. At some point, it might
be nice to have an "add_option_if_missing" and apply that across the whole
of the test infra. However this is not something for late in stage 4. So
the solution here is to prune the warning - the effect of the duplicate in
the libstdc++ testsuite is not important; it will make the exes very slightly
larger but it won't alter the paths that are presented for loading the
runtimes.
libstdc++-v3/ChangeLog:
* testsuite/lib/prune.exp: Prune ld warning about duplicatei
rpaths.

dynamic stack allocation not supported'
In Subversion r217296 (Git commit e2acc079ff125a869159be45371dc0a29b230e92)
"Testsuite alloca fixes for ptx", effective-target 'alloca' was added to mark
up test cases that run into the nvptx back end's non-support of dynamic stack
allocation. (Later, nvptx gained conditional support for that in
commit 3861d362ec7e3c50742fc43833fe9d8674f4070e
"nvptx: PTX 'alloca' for '-mptx=7.3'+, '-march=sm_52'+ [PR65181]", but on the
other hand, in commit f93a612fc4567652b75ffc916d31a446378e6613
"bpf: liberate R9 for general register allocation", the BPF back end joined
"the list of targets that do not support alloca in target-support.exp".
Manually maintaining the list of test cases requiring effective-target 'alloca'
is notoriously hard, gets out of date quickly: new test cases added to the test
suite may need to be analyzed and annotated, and over time annotations also may
need to be removed, in cases where the compiler learns to optimize out
'alloca'/VLA usage, for example. This commit replaces (99 % of) the manual
annotations with an automatic scheme: turn test cases into UNSUPPORTED if
running into 'sorry, unimplemented: dynamic stack allocation not supported'.

For GCN, this avoids ICEs further down the compilation pipeline. For nvptx,
there's effectively no change: in presence of exception handling constructs,
instead of 'sorry, unimplemented: target cannot support nonlocal goto', we

Additionally, turn test cases into UNSUPPORTED if running into

In Subversion r268025 (Git commit 3f21b8e3f7be32dd2b3624a2ece12f84bed545bb)
"Add dg-require-effective-target exceptions", effective-target 'exceptions'
was added, which "says that AMD GCN does not support [exception handling]".
In Subversion r279246 (Git commit a9046e9853024206bec092dd63e21e152cb5cbca)
"MSP430: Add -fno-exceptions multilib", effective-target 'exceptions_enabled'
was added "to check if the testing configuration supports exceptions". Testing
"if exceptions are unsupported or disabled (e.g. by passing -fno-exceptions)"
works as expected if exception handling is disabled at the front-end level
('-fno-exceptions'; the "exceptions are [...] disabled" case):
exceptions_enabled2066068.cc: In function ‘void foo()’:
exceptions_enabled2066068.cc:3:27: error: exception handling disabled, use ‘-fexceptions’ to enable
However, effective-target 'exceptions_enabled' additionally assumes that
"If exceptions aren't supported [by the target], then they're not enabled".
This is not correct: it's not unlikely that, in presence of explicit/implicit
'-fexceptions', exception handling code gets fully optimized away by the
compiler, and therefore effective-target 'exceptions_enabled' test cases may
PASS even for targets that don't support effective-target 'exceptions'; these
two effective-targets are orthogonal concepts.
(For completeness: code with trivial instances of C++ exception handling may
translate into simple '__cxa_allocate_exception', '__cxa_throw' function calls
without requiring any back end-level "exceptions magic", and then trigger
unresolved symbols at link time, if these functions are not available.)
This change only affects GCN, as that one currently is the only target declared
as not supporting effective-target 'exceptions'.

Newer newlib trigger warnings about certain functions not implemented
(_getentropy) when testing libstdc++-v3.
Since 2018 (circa binutils-2.31) the "in function" prefix isn't
capitalized for those "not implemented" warnings when generated from
the linker (a GNU ld feature used by newlib). Dejagnu up to and
including at least dejagnu-1.6.3 (and git @ 42979bd3b9) assumes a
capital "In function", leaving that part unpruned, and boom we have
thousands of "excess errors" from the libstdc++-v3 testsuite.
While gcc/testsuite/lib/prune.exp:prune_gcc_output already deals with
this quirk with a vastly more generic pattern, I choose this simpler
tweak.

Follow-up to recent commit 515da03a838db05443ebcc4c543a405bed764188
"libstdc++: Add file-io-diff to replace @diff@ markup in I/O tests".
Currently, if a 'dg-final' action 'file-io-diff' passes, we print nothing
(should: 'PASS: [...]'), but if it fails, we just print: 'FAIL: files differ',
for example ('*.log' file):
[...]
FAIL: 27_io/basic_ostream/inserters_other/wchar_t/2.cc -std=gnu++17 (test for excess errors)
[...]
UNRESOLVED: 27_io/basic_ostream/inserters_other/wchar_t/2.cc -std=gnu++17 compilation failed to produce executable
diff: wostream_inserter_other_in.txt: No such file or directory
diff: wostream_inserter_other_out.txt: No such file or directory
FAIL: files differ
diff: wostream_inserter_other_in.txt: No such file or directory
diff: wostream_inserter_other_out.txt: No such file or directory
When later the '*.sum' files get sorted, these 'FAIL: files differ' instances
aren't grouped anymore with the other test cases' results, but they appear en
bloc, lexically sorted between ('e[...]' and 's[...]'), for example:
[...]
PASS: ext/vstring/types/23767.cc -std=gnu++17 (test for excess errors)
FAIL: files differ
FAIL: files differ
FAIL: files differ
PASS: special_functions/01_assoc_laguerre/check_nan.cc -std=gnu++17 (test for excess errors)
[...]
Also, we shouldn't emit the actual 'diff' into the '*.sum' file, but just into
the '*.log* file, and there's no need for 'spawn'/'expect', as we're not
matching any specific messages.

The problem here is that v3_additional_files will have a space
at the begining of the string as dg-additional-files will append
`" " $files` to it. Then when split is called on that string,
there will be an empty file and copying a dir will just fail for
remote/sim testing (I didn't look at why it works for native
testing though).
Ran a full libstdc++ testsuite using a sim board for testing.

This adds a new dg-final action to compare two files after a test has
run, so that we can verify that fstream operations produce the expected
results. With this change, all uses of @diff@ that seem potentially
useful have been converted to actually compare the files and FAIL if
they differ.
The file-io-diff action can take two arguments naming the files to be
compared, or for convenience it can take a single string and will
compare STR.tst and STR.txt, as that's how it's commonly used.
Additionally, all remaining uses of @require@ are converted to
dg-additional-files directives, so that the TODO in libstdc++.exp can
be resolved.

We can replace the @require@ markup with { dg-additional-files ... }
directives, so that the required files are explicitly named and are
explicitly copied into place for tests that require it. This will allow
a later change to remove the "Copy all required data files" step in the
proc libstdc++_init in testsuite/lib/libstdc++.exp that is marked TODO.
This commit uses dg-additional-files for a subset of the files that
contain @require@.
Also remove the @diff@ markup where appears to be copy & pasted from
other test files, and so serves no purpose. For example, there is no
output file created by 27_io/basic_ifstream/cons/char/1.cc so there is
nothing for @diff@ to compare. Maybe the purpose was to check that
reading the .tst file with an ifstream doesn't change it, but we've
survived without doing those comparisons for many years so I think we
can remove those cases of @diff@ markup.

libatomic hasn't been ported to vxworks. Most of the stdatomic.h and
<atomic> underlying requirements are provided by builtins and libgcc,
and the vxworks libc already provides remaining __atomic symbols, so
porting libatomic doesn't seem to make sense.
However, some of the target arch-only tests in
add_options_for_libatomic cover vxworks targets, so we end up
attempting to link libatomic in, even though it's not there.
Preempt those too-broad tests.

Support for Solaris 11.3 had already been obsoleted in GCC 13. However,
since the only Solaris system in the cfarm was running 11.3, I've kept
it in tree until now when both Solaris 11.4/SPARC and x86 systems have
been added.
This patch actually removes the Solaris 11.3 support. Apart from
several minor simplifications, there are two more widespread changes:
* In Solaris 11.4, libsocket and libnsl were folded into libc, so
there's no longer a need to link them explictly.
* Since Solaris 11.4, Solaris includes all crts needed by gcc (like
crt1.o and gcrt1.o) with the base system. All workarounds to provide
fallbacks can thus go.
Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11 (as/ld, gas/ld, and gas/gld) as well as Solaris
11.3/x86 to ascertain that version is actually rejected.

GDB emits end of lines as \r\n, we currently match any >0 number of
either \n or \r, possibly leading to mismatches under racy conditions.
I noticed this while running the GCC testsuite using the equivalent of
GDB's READ1 feature [1] which helps detecting bufferization issues.
We try to match
\n$1 = empty std::tuple\r
against {^(type|\$([0-9]+)) = ([^\n\r]*)[\n\r]+} which fails because
of the leading \n (which was left in the buffer after the previous
"skipping" pattern matched the preceding \r).
This patch accepts any number of leading \n and/or \r in the "got" clause.
Also take this opportunity to quote \r and \r in the logs, to make
debugging such issues easier.
Tested on aarch64-linux-gnu.

Darwin has a separate debug linker, which is invoked when the command
line contains source files and debug is enabled.
Using /dev/null as the executable name does not, therefore, work when
debug is enabled, since the debug linker does not accept /dev/null as
a valid executable name.
The leads to incorrectly UNSUPPORTED testcases because of the unintended
error result from the test compilation.
The solution here is to use a temporary file that is deleted at the
end of the test (which is the mechanism used elsewhere)

This adds two new static_assert messages to the internals of
std::make_format_args to give better diagnostics for invalid format
args. Rather than just getting an error saying that basic_format_arg
cannot be constructed, we get more specific errors for the cases where
std::formatter isn't specialized for the type at all, and where it's
specialized but only meets the BasicFormatter requirements and so can
only format non-const arguments.
Also add a test for the existing static_assert when constructing a
format_string for non-formattable args.
libstdc++-v3/ChangeLog:
* include/std/format (_Arg_store::_S_make_elt): Add two
static_assert checks to give more user-friendly error messages.
* testsuite/lib/prune.exp (libstdc++-dg-prune): Prune another
form of "in requirements with" note.
* testsuite/std/format/arguments/args_neg.cc: Check for
user-friendly diagnostics for non-formattable types.

When running the DejaGNU testsuite on a toolchain built for native
Windows, the path /dev/null can't be used to open a stream to void.
On native Windows, the resource is instead named "nul".
In 17_intro/tag_type_explicit_ctor.cc, the following statement would
fail to match when the DejaGNU testsuite is running in cygwin with a
native toolchain.
// dg-error 53 "explicit" "" { target hosted }
The "target hosted"-check is using cpp to verify if _GLIBCXX_HOSTED is
defined and discards the output by simply redirecting it to /dev/null.
In v3_target_compile, it's overridden to "nul" for MinGW targets, but
the same rule applies when host is cygwin, so replace the condition
with a check for Windows.
The error in the log would look like this for the "target hosted" check:
cc1plus.exe: fatal error: opening output file /dev/null: No such file or directory
The tag_type_explicit_ctor.cc test fails with this on Windows:
.../tag_type_explicit_ctor.cc:53: error: converting to 'std::defer_lock_t' from initializer list would use explicit constructor 'constexpr std::defer_lock_t::defer_lock_t()'

Patch has been verified on Windows and Linux.

compare and exchange.
This directive can be used to replace uses of dg-require-thread-fence
where an atomic operation is actually used.

This copies the code from the compiler's gcc/testsuite/lib/g++-dg.exp so
that each test can be run multiple times, with different -std options.
This means that we can remove most { dg-options "-std=gnu++20" }
directives from tests, because the testsuite will automatically select
a set of -std options that includes that version.
Tests that should only run for a specific standard (e.g. ones that use
something like { dg-do run { target c++11_only } }) should still specify
that standard with { dg-options "-std=gnu++11" }, which overrides the
automatic selection. But a dg-options that selects a newer standard than
the default can be removed, because that standard will be selected
automatically based on a selector like { target c++20 } in the dg-do
directive. This will allow those tests to be run for more than just the
one they currently hardcode, so that e.g. std::format tests can be run
for all of C++20, C++23 and C++26. Currently that has to be done by
adding a second test file that uses a different dg-options line.
By default most tests will continue to run with only the default dialect
(currently -std=gnu++17) so that the time to run the entire testsuite is
not increased. We can revisit this later if increasing the testsuite
time (and coverage) is acceptable. Libstdc++ developers can easily
override the defaults to run for multiple versions. To test all
versions, either add 'set v3_std_list { 98 11 14 17 20 23 26 }' to
~/.dejagnurc or define GLIBCXX_TESTSUITE_STDS="98,11,14,17,20,23,26" in
the environment.
This should be more efficient than the current way to test with multple
standards, i.e. --target_board=unix{-std=c++14,-std=c++17,-std=c++20},
because today all tests with an explicit -std option hardcoded in them
get run for each target board variation but using the exact same
hardcoded -std every time. With the new approach you can just use the
default --target_board=unix and set GLIBCXX_TESTSUITE_STDS="14,17,20"
and now a test that has { target c++20 } will only run once (and be
UNSUPPORTED twice), instead of running with identical options three
times.
In order to support ~/.dejagnurc and $DEJAGNU files that need to work
with versions of GCC without this change, a new variable is added to
site.tmp to detect whether v3_std_list is supported. That allows e.g.
if { [info exists v3-use-std-list] } {
set v3_std_list { 11 17 23 }
set target_list { "unix{,-m32}" }
} else {
set target_list { "unix{,-std=gnu++2b,-std=gnu++11,-m32}" }
}

Some tests rely on text files with specific content being present in the
test directory. This has historically been done by copying
testsuite/data/*.tst and testsuite/data/*.txt to the test dir at the
start, in the libstdc++_init procedure. Some tests modify their data
files, so if the same test runs more than once in the same directory the
second and subsequent tests will see the modified files, and FAIL
because the content of the file is not in the expected state.
This change adds support for the dg-additional-files directive from the
main compiler testsuite and changes v3_target_compile to copy the
specified files to the directory where the test will run. This ensures
that a fresh copy of the files is present each time the test runs.
Eventually all tests could be transitioned to use dg-additional-files
and then libstdc++_init could be changed to remove the initial copy of
all files. This change only adds dg-additional-files to the tests that
modify their files and FAIL when re-run in the same directory.
The tests that rely on additional data files have comments containing
the strings "@require@" and "@diff@" which seem to be related to the
libstdc++-v3/mkcheck.in testing script that was removed in 2003. Those
comments can be used to find tests that should be migrated to use the
new dg-additional-files support, and then the comments can be removed.

The { dg-add-options no_pch } directive is supposed to add a macro
definition that invalidates the PCH file, and ensures that the #include
directives in the test file are processed as written. But the proc that
adds the options actually removes all existing options, cancelling out
any previous dg-options directive.
This means that using no_pch will cause FAILs in a file that relies on
other options set by an earlier dg-options.
The no_pch directive was added for PR libstdc++/21769 where Janis
suggested adding it as return "$flags -D__GLIBCXX__=99999999" but what
was actually committed didn't include the $flags so replaced them.
Additionally, using no_pch only prevents the precompiled version of
<bits/stdc++.h> from being included, it doesn't prevent the
non-precompiled version being included by -include bits/stdc++.h in the
test flags. Use regsub to filter that out of the options as well.
libstdc++-v3/ChangeLog:
* testsuite/lib/dg-options.exp (add_options_for_no_pch): Remove
any "-include bits/stdc++.h" from options and add the macro to
the existing options instead of replacing them.

The libstdc++ test suite checks whether gdb type printers are
available like so:
set do_whatis_tests [gdb_batch_check "python print(gdb.type_printers)" \
"\\\[\\\]"]
This regexp assumes that the list of printers is empty. However,
sometimes it's convenient to ship a gdb that comes with some default
printers, causing this to erroneously report that gdb is "too old".
I believe the intent of this check is to ensure that gdb.type_printers
exists -- not to check its starting value. This patch changes the
check to accept any Python list as output.
Note that the patch doesn't look for the trailing "]". I tried this
but in my case the output was too long for expect. It seemed fine to
just check the start, as the point really is to reject the case where
the command prints an error message.

Similar to the three commits r14-908, r14-909 and r14-910, the
_GLIBCXX_USE_C99_MATH_TR1 macro is misleading when it is also used for
<cmath>, not only for <tr1/cmath> headers. It is also wrong, because the
configure checks for TR1 use -std=c++98 and a target might define the
C99 features for C++11 but not for C++98.
Add separate configure checks for the <math.h> functions using
-std=c++11 for the checks. Use the new macro defined by those checks in
the C++11-specific parts of <cmath>, and in <complex>, <random> etc.
The check that defines _GLIBCXX_NO_C99_ROUNDING_FUNCS is only needed for
the C++11 <cmath> checks, so remove that from GLIBCXX_CHECK_C99_TR1 and
only do it for GLIBCXX_ENABLE_C99.

The _GLIBCXX_USE_C99_STDINT_TR1 macro (and the comments about it in
acinclude.m4 and config.h) are misleading when it is also used for
<stdint>, not only <tr1/stdint>. It is also wrong, because the
configure checks for TR1 use -std=c++98 and a target might define
uint32_t etc. for C++11 but not for C++98.
Add a separate configure check for the <stdint.h> types using -std=c++11
for the checks. Use the result of that separate check in <cstdint> and
most other places that still depend on the macro (many uses of that
macro have been removed already). The remaining uses of the STDINT_TR1
macro are really for TR1, or are in the src/c++11/compatibility-*.cc
files, where we don't want/need to change the condition they depend on
(if those symbols were only exported when <stdint.h> types were
available for -std=c++98, then that's the condition we should continue
to use for whether to export the compat symbols now).

This reimplements the GNU threads library on native Windows (except for the
Objective-C specific subset) using direct Win32 API calls, in lieu of the
implementation based on semaphores. This base implementations requires
Windows XP/Server 2003, which was the default minimal setting of MinGW-W64
until end of 2020. This also adds the support required for the C++11 threads,
using again direct Win32 API calls; this additional layer requires Windows
Vista/Server 2008 and is enabled only if _WIN32_WINNT >= 0x0600.
This also changes libstdc++ to pass -D_WIN32_WINNT=0x0600 but only when the
switch --enable-libstdcxx-threads is passed, which means that C++11 threads
are still disabled by default *unless* MinGW-W64 itself is configured for
Windows Vista/Server 2008 or later by default (this has been the case in
the development version since end of 2020, for earlier versions you can
configure it --with-default-win32-winnt=0x0600 to get the same effect).
I only manually tested it on i686-w64-mingw32 and x86_64-w64-mingw32 but
AdaCore has used it in their C/C++/Ada compilers for 3 years now and the
30_threads chapter of the libstdc++ testsuite was clean at the time.

This is the largest missing piece of C++20 support. Only the cxx11 ABI
is supported, due to the use of std::string in the API for time zones.
For the old gcc4 ABI, utc_clock and leap seconds are supported, but only
using a hardcoded list of leap seconds, no up-to-date tzdb::leap_seconds
information is available, and no time zones or zoned_time conversions.
The implementation currently depends on a tzdata.zi file being provided
by the OS or the user. The expected location is /usr/share/zoneinfo but
that can be changed using --with-libstdcxx-zoneinfo-dir=PATH. On targets
that support it there is also a weak symbol that users can override in
their own program (which also helps with testing):
extern "C++" const char* __gnu_cxx::zoneinfo_dir_override();
If no file is found, a fallback tzdb object will be created which only
contains the "Etc/UTC" and "Etc/GMT" time zones.
A leapseconds file is also expected in the same directory, but if that
isn't present then a hardcoded list of leapseconds is used, which is
correct at least as far as 2023-06-28 (and it currently looks like no
leap second will be inserted for a few years).
The tzdata.zi and leapseconds files from https://www.iana.org/time-zones
are in the public domain, so shipping copies of them with GCC would be
an option. However, the tzdata.zi file will rapidly become outdated, so
users should really provide it themselves (or convince their OS vendor
to do so). It would also be possible to implement an alternative parser
for the compiled tzdata files (one per time zone) under
/usr/share/zoneinfo. Those files are present on more operating systems,
but do not contain all the information present in tzdata.zi.
Specifically, the "links" are not present, so that e.g. "UTC" and
"Universal" are distinct time zones, rather than both being links to the
canonical "Etc/UTC" zone. For some platforms those files are hard links
to the same file, but there's no indication which zone is the canonical
name and which is a link. Other platforms just store them in different
inodes anyway. I do not plan to add such an alternative parser for the
compiled files. That would need to be contributed by maintainers or
users of targets that require it, if making tzdata.zi available is not
an option. The library ABI would not need to change for a new tzdb
implementation, because everything in tzdb_list, tzdb and time_zone is
implemented as a pimpl (except for the shared_ptr links between nodes,
described below). That means the new exported symbols added by this
commit should be stable even if the implementation is completely
rewritten.
The information from tzdata.zi is parsed and stored in data structures
that closely model the info in the file. This is a space-efficient
representation that uses less memory that storing every transition for
every time zone. It also avoids spending time expanding that
information into time zone transitions that might never be needed by the
program. When a conversion to/from a local time to UTC is requested the
information will be processed to determine the time zone transitions
close to the time being converted.
There is a bug in some time zone transitions. When generating a sys_info
object immediately after one that was previously generated, we need to
find the previous rule that was in effect and note its offset and
letters. This is so that the start time and abbreviation of the new
sys_info will be correct. This only affects time zones that use a format
like "C%sT" where the LETTERS replacing %s are non-empty for standard
time, e.g. "Asia/Shanghai" which uses "CST" for standard time and "CDT"
for daylight time.
The tzdb_list structure maintains a linked list of tzdb nodes using
shared_ptr links. This allows the iterators into the list to share
ownership with the list itself. This offers a non-portable solution to a
lifetime issue in the API. Because tzdb objects can be erased from the
list using tzdb_list::erase_after, separate modules/libraries in a large
program cannot guarantee that any const tzdb& or const time_zone*
remains valid indefinitely. Holding onto a tzdb_list::const_iterator
will extend the tzdb object's lifetime, even if it's erased from the
list. An alternative design would be for the list iterator to hold a
weak_ptr. This would allow users to test whether the tzdb still exists
when the iterator is dereferenced, which is better than just having a
dangling raw pointer. That doesn't actually extend the tzdb's lifetime
though, and every use of it would need to be preceded by checking the
weak_ptr. Using shared_ptr adds a little bit of overhead but allows
users to solve the lifetime issue if they rely on the libstdc++-specific
iterator property.

Currently we only reject std::make_signed_t<bool> but not cv bool.
Similarly for std::make_unsigned_t<cv bool>.
As well as making those ill-formed, this adds a requires-clause to the
make_signed and make_unsigned primary templates. This makes
non-integral, non-enum cases fail immediately with a clear error, rather
than giving an error about __make_signed_selector<T, false, false> being
incomplete.

This allows the library to switch to freestanding mode when compiling
with the -ffreestanding flag. This means you don't need a separate
libstdc++ build configured with --disable-hosted-libstdcxx in order to
compile for a freestanding environment.

-fno-freestanding to override any -ffreestanding in the test flags.

The above, as well as net/internet/resolver/ops tests and
net/timer/waitable/cons.cc, will fail early at runtime unless mkfifo
is enabled in the RTEMS configuration, because the io_context ctor
throws when pipe() fails.
