Add ability to build with clang compiler (on linux):

  • Fix clang-specific compilation errors and warnings
  • Add tasks in CI, that check ability to build with clang

Add `set -e` in build.sh to stop build process on error
Add SYSTEM flag to add_subdirectory(".../googletest") in CMakeLists.txt
to supress warnings from the inside of googletest
Replace INSTANTIATE_TEST_CASE_P, which is deprecated, with
INSTANTIATE_TEST_SUITE_P in NDVerifier tests
Mark unused fields as [[maybe_unused]], because clang produces warning
that becomes an error in Debug mode. Use MAYBE_UNUSED macro, because
g++ produces warning when [[maybe_unused]] macro is present, and clang --
when it isn't.
Convert double literals to model::DoubleType and model::IntType explicitly, because
otherwise clang produces a warning, that becomes an error in debug mode
Add run_tests_clang action in core_tests.yml
Also, work around clang-18 bug
- Check that column is numeric *before* casting it to INumericType
in DataStats::GetMedianAD
- Don't process empty vector in GetPartition in gfd_validation.cpp
- Disable tests causing float-to-long cast when result is infinity
Add Clang installation guide to README.md
Use simple RAII wrapper of std::thread instead of std::jthread
when the latter isn't implemented (which is the case in Apple Clang)
Use custom implementations of std::bitset::_Find_dirst and
_Find_next when gcc intrinsics aren't availible
Use some tricks with boost::dynamic_bitset in fd_tree_bitset
to avoid GCC intrinsics _Find_first and _Find_next
Use std::chrono::high_resolution_clock instead of
std::chrono::_V2::high_resolution_clock in fastod/util/timer.h,
because symbol versioning is gcc-specific
Make GetByte function contexpr only if std::vector::operator[]
is contexpr (which isn't on old versions of GCC)
Shift bitset 1 bit left in CreateDynamicBitset (fallback variant),
as it done in main (gcc intrinsic) variant. Also, rename this function
for clarity.
Use system_clock everywhere instead of mix of system_clock and
high_resolution_clock in Cords::ExecuteInternal
Add instructions how to build boost with clang
Link clang build with libc++ instead of libstc++ in CI
Also build boost with clang in CI
Don't violate implicit noexcept(true) in AutoJoinThread's destructor
Version 1.13.0 of googletest produces "narrowing conversion" warning due to a bug
(issue #4206, google/googletest#4206) when building
with Clang. This bug was fixed in 1.14.0 (commit 3044657,
google/googletest@3044657)
Install all LLVM packages in install-clang action in CI,
not only LLVM and Clang
Use concepts to test GCC intrinsics precence, instead of SFINAE
Use stable_sort instead of sort to avoid relying on
unspecified behaviour (wheter sort preserves order of equal elements)
Sort pairs by value if frequencies are equal in Cords'
FrequencyHandler::InitFrequencyHandler
Use reverse iterators to traverse set in reverse order, instead of
messing with normal iterators
Disable alloc-dealloc-mismatch check as it's false positive
on Ubuntu (see comment in CMakeLists.txt)
Remove comment about libc++abi in README

run_tests is needed to be renamed to run_tests_gcc and run_tests_clang in branch protection rules for CI to pass. This also applies to macOS PR.
