6362 Add hmin and hmax overloads for simd and const_where_expression.
6363 * include/experimental/bits/simd_scalar.h
6364 (_SimdImplScalar::_S_reduce): Make unused _BinaryOperation
6365 parameter const-ref to allow calling _S_reduce with an rvalue.
6366 * testsuite/experimental/simd/tests/reductions.cc: Add tests for
6367 hmin and hmax. Since the compiler statically determined that all
6368 tests pass, repeat the test after a call to make_value_unknown.
6370 2021-02-03 Matthias Kretz <kretz@kde.org>
6372 * testsuite/experimental/simd/tests/bits/verify.h (verify): Add
6373 instruction pointer data member. Ensure that the `if (m_failed)`
6374 branch is always inlined into the calling code. The body of the
6375 conditional can still be a function call. Move the get_ip call
6376 into the verify ctor to simplify the ctor calls.
6377 (COMPARE): Don't mention the use of all_of for reduction of a
6378 simd_mask. It only distracts from the real issue.
6380 2021-02-03 Matthias Kretz <kretz@kde.org>
6382 * testsuite/experimental/simd/driver.sh: Abstract reading test
6383 options into read_src_option function. Read skip, only,

6404 conditional on _ARCH_PWR10.

6406 _MaskImplPpc and use it as _MaskImpl when __ALTIVEC__ is

6409 _SuperImpl for optimizations and correctness.
6410 * include/experimental/bits/simd_ppc.h: Add _MaskImplPpc.
6411 (_MaskImplPpc::_S_popcount): Implement via vec_cntm for POWER10.
6412 Otherwise, for >=int use -vec_sums divided by a sizeof factor.
6413 For <int use -vec_sums(vec_sum4s(...)) to sum all mask entries.
6415 2021-02-03 Matthias Kretz <kretz@kde.org>
6417 * testsuite/experimental/simd/driver.sh: Remove executable on
6418 SIGINT. Process compiler and test executable output: In verbose
6419 mode print messages immediately, limited to 1000 lines and
6420 breaking long lines to below $COLUMNS (or 1024 if not set).
6421 Communicating the exit status of the compiler / test with the
6422 necessary pipe is done via a message through stdout/-in.
6424 2021-02-03 Matthias Kretz <kretz@kde.org>
6426 * testsuite/Makefile.am: Ensure .simd.summary is empty before
6427 collecting a new summary.
6428 * testsuite/Makefile.in: Regenerate.
6430 2021-02-03 Matthias Kretz <kretz@kde.org>
6432 * testsuite/experimental/simd/generate_makefile.sh: Use
6433 different variables internally than documented for user
6434 overrides. This makes internal append/prepend work as intended.
6436 2021-02-03 Matthias Kretz <kretz@kde.org>
6438 * testsuite/experimental/simd/driver.sh (verify_test): Print
6439 test output on run xfail. Do not repeat lines from the log that
6440 were already printed on stdout.
6441 (test_selector): Make the compiler flags pattern usable as a
6443 (toplevel): Trap on SIGINT and remove the log and sum files.
6444 Call timout with --foreground to quickly terminate on SIGINT.
6445 * testsuite/experimental/simd/generate_makefile.sh: Simplify run
6446 targets via target patterns. Default DRIVEROPTS to -v for run
6447 targets. Remove log and sum files after completion of the run
6448 target (so that it's always recompiled).
6449 Place help text into text file for reasonable 'make help'
6452 2021-02-03 Matthias Kretz <kretz@kde.org>
6454 * include/experimental/bits/simd.h: Remove unnecessary static
6455 assertion. Allow sizeof(8) integer __intrinsic_type to enable
6456 the necessary mask type.
6458 2021-02-03 Matthias Kretz <kretz@kde.org>
6460 * include/experimental/bits/simd.h: Let __intrinsic_type<long
6461 double, N> be valid if sizeof(long double) == sizeof(double) and
6462 use a __vector double as member type.
6464 2021-02-03 Matthias Kretz <kretz@kde.org>
6466 * include/experimental/bits/simd.h (__is_intrinsic_type): New
6467 internal type trait. Alias for __is_vector_type on x86.

6478 expensive, and xfail markers. They can select on type, ABI tag
6479 subset number, target-triplet, and compiler flags.
6480 * testsuite/experimental/simd/generate_makefile.sh: The summary
6481 now includes lines for unexpected passes and expected failures.
6482 If the skip or only markers are only conditional on the type, do
6483 not generate rules for those types.
