The problem here is that the pp() information (which is what ppfunc() parses) has the class name, but in a mangled format. We'd have to add a C++ demangler for this to work properly. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 3+ messages in thread

We'd have to add a C++ > demangler for this to work properly. Just to be clear here, I'm not suggesting we put a C++ demangler in the kernel modules. I'm suggesting that we add enough code to the translator to put the unmangled C++ class/function name ("CLASS::FUNCTION") as part of the probe point name field the translator emits. Then a ppfunc() variant could extract CLASS::FUNCTION from the full probe name field. (Note that we'd still have mangled C++ names in backtraces that would need to be passed through c++filt to get demangled.) -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 3+ messages in thread
