# The checks starting with - are disabled. Most of them because we do not need/want them,
# but following warnings are disabled as they cause errors or false warnings in our code.
# Causes clang-tidy-12 internal segfaults:
# -readability-static-accessed-through-instance
# Gives warning in dune-alugrid/dune/alugrid/3d/grid_inline.hh:49:20 for dune/xt/test/grid/dgf_gridprovider.cc:
# Call to virtual method ALU3dGrid::createALUGrid during construction bypasses virtual dispatch
# -clang-analyzer-optin.cplusplus.VirtualCall,
# Gives false positives, see https://github.com/llvm/llvm-project/issues/40486 and https://bugs.llvm.org/show_bug.cgi?id=44247
# -clang-analyzer-cplusplus.NewDeleteLeaks,
# These cause a lot of warnings for static inline functions in headerchecks because they are not used in that compilation unit
# -clang-diagnostic-unneeded-internal-declaration
# -clang-diagnostic-unused-function
