| 4 | # names demangling, so we're piping its output to c++filt(1) tool which does it. |
| 5 | # But c++filt(1) comes with XCode (as a part of GNU binutils), so it doesn't |
| 6 | # guaranteed to exist on a system. |
| 7 | # |
| 8 | # An alternative approach is to perform demangling in tick processor, but |
| 9 | # for GNU C++ ABI this is a complex process (see cp-demangle.c sources), and |
| 10 | # can't be done partially, because term boundaries are plain text symbols, such |
| 11 | # as 'N', 'E', so one can't just do a search through a function name, it really |
| 12 | # needs to be parsed, which requires a lot of knowledge to be coded in. |
