Demangle types #23

Open xPaw opened 1 month ago

xPaw commented 1 month ago

It's a TODO: https://github.com/ianlancetaylor/demangle/blob/81f5be970ecae4046912a026004100b0535be16e/c%2B%2Bfilt.go#L51

echo "N8tinyxml27MemPoolE" | c++filt -t

tinyxml2::MemPool

When does this actually come up in practice?

Dumping strings from a binary

ianlancetaylor commented 1 month ago

Thanks, but can you give me an example? In a binary I would expect all such strings to be part of a complete symbol name. When does a binary contain strings that are only mangled types that are not part of a complete symbol?

xPaw commented 1 month ago

It's basically a strings dump of the file (using some Go code to scan sections to find strings though), it should be complete string if it's surrounded by null bytes?

Thanks, but that is not quite an example. When do you find a C++ type string in a string dump of a file. Why would that happen?
