Finds macros that can have unexpected behaviour due to missing parentheses.
Macros are expanded by the preprocessor as-is. As a result, there can be unexpected behaviour; operators may be evaluated in unexpected order and unary operators may become binary operators, etc.
When the replacement list has an expression, it is recommended to surround it with parentheses. This ensures that the macro result is evaluated completely before it is used.
It is also recommended to surround macro arguments in the replacement list with parentheses. This ensures that the argument value is calculated properly.

Override this to register PPCallbacks
with Compiler
.
This should be used for clang-tidy checks that analyze preprocessor- dependent properties, e.g. the order of include directives.
Reimplemented from clang::tidy::ClangTidyCheck.
