ChangeLog: * detail.h:
Copied and modified large parts of the vec-builtin and x86 implementation in <experimental/simd>. Branching on CPU features now uses conditions derived from template parameters, not globals. This should make it easier to adopt multi-arch / multi-veclen compilation at some point (once the compiler supports it). Reduced the number of template and lambda instantiations, to reduce compile time and space requirements. Notably, iterations on index spaces now use a single lambda instead of a function template invoking one lambda specialization per index. Also removing the use of std::invoke has a *huge* impact. ChangeLog: * Makefile: Add more tests and compile them in many different configurations. * arm_detail.h: New file. * constexpr_tests.c++: Add another test for size 7. * constexpr_wrapper.h: Update copyright. * detail.h: Copy and adjust several functions from experimental/simd.

Preliminary support for std::float(16|32|64)_t. * detail_bitmask.h: New file. * flags.h: Add TS-like load/store flags. * fwddecl.h: Remove TS usage. Add _VecAbi, _Avx512Abi, and _ScalarAbi. * interleave.h: Update copyright. * iota.h: Update copyright. Reduce lambda instantiations. * mask_reductions.h: Move x86 specific code into simd_x86.h. Call into Abi implementation types when available. * permute.h: Update copyright. Replace always_inline macro. * power_detail.h: New file. * simd.h: Add mossing unary operators +, -, ~, ++, --.

ChangeLog: * Makefile: Generate all check targets and help targets without using a shell using the foreach and eval make functions. Call a submake in the check recipes with a randomized set of concrete checks to run.
Change _VecAbi and _Avx512Abi to use number of elements as template parameter instead of number of bytes. This simplifies _S_size, _S_full_size, and _S_is_partial, which don't need to be templates anymore. More importantly, it removes the need for passing the value-type as a template parameter to some of the Impl functions. Remove unused _SimdBase and _MaskBase. Have _SimdTraits depend on build flags, adding a new _SimdMaskTraits to work out the right ABI for AVX w/o AVX2. ChangeLog: * arm_detail.h: Include detail.h. * constexpr_tests.c++: Add sanity checks relating to AVX w/o AVX2. * detail.h (__make_dependent): New. (_SimdTraits): Add __build_flags template argument. (_SimdMaskTraits): New. * fwddecl.h (_VecAbi, _Avx512Abi): Change template parameter name. (__native_abi_impl_recursive): Adjust for change from bytes to width. (_DeduceAbi): Move default definition to simd_abi.h. * power_detail.h: Include detail.h. * simd.h (simd::mask_type): Test for void not vectorizable to document intent. (basic_simd(basic_simd_mask) deduction guide): Defer ABI tag deduction to __simd_abi_for_mask trait. * simd_abi.h: Adjust for ABI tag template parameter change from bytes to width. (_AbiCombine): Move from std::__detail to std namespace. (_SimdImplArray::_S_masked_assign): Handle some AVX w/o AVX2 cases. * simd_builtin.h: Adjust for ABI tag template parameter change from bytes to width. * simd_mask.h (__simd_abi_for_mask): New. * simd_scalar.h: Remove template heads from _S_size, _S_full_size, and _S_is_partial. Remove _SimdBase, _MaskBase. * simd_x86.h: Adjust for ABI tag template parameter change. (_SimdMaskTraits): Specialize for the AVX w/o AVX2 case. (_ImplBuiltin::_S_load): Overload for AVX512 bitmasks. (_ImplBuiltin::_S_select_bitmask): Swap argument names. Enable constexpr eval. (_ImplBuiltin::_S_select): Enable constexpr eval. Disambiguate overloads when _MaskMember<_TV> is a bitmask type. (_ImplBuiltin::_S_masked_assign): Broadcast scalar argument to a vector when calling _S_select_bitmask.

(_ImplBuiltin::_S_bit_shift_right, _S_bit_shift_left): Replace several reinterpret_cast with __vec_bitcast_trunc on return. Adjust ABI/Impl type needed after template parameter change. Fix conditions for sizeof<16 inputs. (_ImplBuiltin::_S_ldexp): Use __make_dependent to instantiate _Rebind only on use of _S_ldexp. Start of supporting sizeof<16 inputs. * unittest.h (instantiate_tests_for_value_type): Sanity check that if simd<T, N> is usable, then the corresponding mask is also usable. * x86_detail.h (__x86_builtin_fp): New. (__to_x86_intrin): Normalize floating-point types using __x86_builtin_fp.
60k check targets: - 0.6s for 'make help', listing all 60k targets - 0.5s for 'make debug', parsing the whole Makefile and a bit of output All check targets are shuffled differently on every make invocation without significant overhead. The 'check' target works without sub-make, whereas all the other check-% targets recurs once (which might become a problem with too long command lines). Per -march, a header is generated, a PCH is built from it, and the header is automatically included into the builds. ChangeLog: * Makefile: Rewrite.
ChangeLog: * Makefile: Remove stale help/% target. Accommodate new unittest.h location. Remove -I. flag. Fix required check target. * tests/misc.cpp: Adjust unittest.h include. * tests/shift_left.cpp: Likewise. * tests/shift_right.cpp: Likewise. * unittest.h: Renamed to unittest.h.
ChangeLog: * Makefile: Require 0 failed tests or fail with non-zero exit status.
Use icerun for running tests to enable -j<large number>. ChangeLog: * Makefile: Run tests in icerun. Compile and link in one step if DIRECT is non-empty. Document DIRECT in help target. Unconditionally set DIRECT=1 without icecream. Build without icecream wrapper but with icerun when DIRECT is non-empty.
ChangeLog: * Makefile: Adjust for unittest.h changes. * tests/misc.cpp: Replace main() with register_tests call. * tests/shift_left.cpp: Likewise. * tests/shift_right.cpp: Likewise. * tests/unittest.h: Move into unittest_pch.h, keeping only instantiate_tests_for_value_type.
