From: Azat Khuzhin <a3at.m...@gmail.com> You can't pass demangled name into "perf probe", because of special chars: ./perf probe -f -x /tmp/a.out 'foo(int)' Semantic error :There is non-digit char in line number.
And you can't even pass without demangling (because it search symbol in DSO with demangle=true): ./perf probe -f -x /tmp/a.out _Z3fooi no symbols found in /tmp/a.out, maybe install a debug package? However: nm /tmp/a.out | grep foo 000000000040056d T _Z3fooi After this patch, using the next command: ./perf probe -f --no-demangle -x /tmp/a.out _Z3fooi probe will be successfully added.
