Matthias Kretz 02e32295b2 libstdc++: Add simd testsuite
Add a new check-simd target to the testsuite. The new target creates a
subdirectory, generates the necessary Makefiles, and spawns submakes to
build and run the tests. Running this testsuite with defaults on my
machine takes half of the time the dejagnu testsuite required to only
determine whether to run tests. Since the simd testsuite integrated in
dejagnu increased the time of the whole libstdc++ testsuite by ~100%
this approach is a compromise for speed while not sacrificing coverage
too much. Since the test driver is invoked individually per test
executable from a Makefile, make's jobserver (-j) trivially parallelizes
testing.

Testing different flags and with simulator (or remote execution) is
possible. E.g. `make check-simd DRIVEROPTS=-q
target_list="unix{-m64,-m32}{-march=sandybridge,-march=skylake-avx512}{,-
ffast-math}"`
runs the testsuite 8 times in different subdirectories, using 8
different combinations of compiler flags, only outputs failing tests
(-q), and prints all summaries at the end. It skips most ABI tags by
default unless --run-expensive is passed to DRIVEROPTS or
GCC_TEST_RUN_EXPENSIVE is not empty.

To use a simulator, the CHECK_SIMD_CONFIG variable needs to point to a
shell script which calls `define_target <name> <flags> <simulator>` and
set target_list as needed. E.g.:
case "$target_triplet" in
x86_64-*)
  target_list="unix{-march=sandybridge,-march=skylake-avx512}
  ;;
powerpc64le-*)
  define_target power8 "-static -mcpu=power8" "/usr/bin/qemu-ppc64le -cpu
power8"
  define_target power9 -mcpu=power9 "$HOME/bin/run_on_gcc135"
  target_list="power8 power9{,-ffast-math}"
  ;;
esac

libstdc++-v3/ChangeLog:

	* scripts/check_simd: New file. This script is called from the
	the check-simd target. It determines a set of compiler flags and
	simulator setups for calling generate_makefile.sh and passes the
	information back to the check-simd target, which recurses to the
	generated Makefiles.
	* scripts/create_testsuite_files: Remove files below simd/tests/
	from testsuite_files and place them in testsuite_files_simd.
	* testsuite/Makefile.am: Add testsuite_files_simd. Add
	check-simd target.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/experimental/simd/driver.sh: New file. This script
	compiles and runs a given simd test, logging its output and
	status. It uses the timeout command to implement compile and
	test timeouts.

	and run the tests and collect the logs into a single log file.

README

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
