Write a line to the log when using a testsuite_files file.
libstdc++-v3/ChangeLog:
* testsuite/libstdc++-dg/conformance.exp: Add log line when
using testsuite_files.
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}" }
}

Adds <experimental/simd>.
This implements the simd and simd_mask class templates via
[[gnu::vector_size(N)]] data members. It implements overloads for all of
<cmath> for simd. Explicit vectorization of the <cmath> functions is not
finished.
The majority of functions are marked as [[gnu::always_inline]] to enable
quasi-ODR-conforming linking of TUs with different -m flags.
Performance optimization was done for x86_64. ARM, Aarch64, and POWER
rely on the compiler to recognize reduction, conversion, and shuffle
patterns.
Besides verification using many different machine flages, the code was
also verified with different fast-math flags.
