/* Module to match qualified C++ procnames "fuzzily", that is up to namescapes and templating. In
|
|
particular, this deals with the following issues:
|
|
|
|
1. 'std::' namespace may have inline namespace afterwards: std::move becomes std::__1::move. This
|
|
happens on libc++ and to some extent on libstdc++. To work around this problem, make matching
|
|
against 'std::' more fuzzier: std::X::Y::Z will match std::.*::X::Y::Z (but only for the
|
|
'std' namespace).
|
|
|
|
2. The names are allowed not to commit to a template specialization: we want std::move to match
|
|
std::__1::move<const X&> and std::__1::move<int>. To do so, comparison function for qualifiers
|
|
will ignore template specializations.
|
|
|
|
For example:
|
|
["std", "move"]:
|
|
matches: ["std", "blah", "move"]
|
|
matches: ["std", "blah<int>", "move"]
|
|
does not match: ["std","blah", "move", "BAD"] - we don't want std::.*::X::.* to pass
|
|
does not match: ["stdBAD", "move"], - it's not std namespace anymore
|
|
|
|
["folly", "someFunction"]
|
|
matches: ["folly","someFunction"]
|
|
matches: ["folly","someFunction<int>"]
|
|
matches: ["folly<int>","someFunction"]
|
|
does not match: ["folly", "BAD", "someFunction"] - unlike 'std' any other namespace needs all
|
|
qualifiers to match
|
|
does not match: ["folly","someFunction<int>", "BAD"] - same as previous example
