Looks at conditionals and finds and replaces cases of cast<>
, which will assert rather than return a null pointer, and dyn_cast<>
where the return value is not captured.

Looks at conditionals and finds and replaces cases of cast<>
, which will assert rather than return a null pointer, and dyn_cast<>
where the return value is not captured.
Additionally, finds and replaces cases that match the pattern var && isa<X>(var)
, where var
is evaluated twice.
Finds cases like these:

Override this to register AST matchers with Finder
.
This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.
You can register as many matchers as necessary with Finder
. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.
If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.
