Base class for all clang-tidy checks.
Attempts to catch calls to TEMP_FAILURE_RETRY with a top-level comparison operation, like TEMP_FAILURE_RETRY(read(...) != N).
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.

Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
