* build: Add -Wsuggest-override We should always use the override specifier when overriding virtual functions. This helps prevent errors when a subclass tries to create a function with the same name as a virtual function in a super-class but with a different purpose. * clang-format * Upload logs on failure * Add override to unsupported.hpp * cmake: Make -Wsuggest-override flag conditional
