Hmm, apparently /usr/bin/perf is only a wrapper script that runs the
"right" version of the perf executable for the current kernel. But the
perf executable (typically inside /usr/lib/linux-tools-VERSION) is part
of the "linux-tools-VERSION" package.
So if I do:
$ sudo apt install
Tested the following on bionic:
$ cat main.cpp

I've installed linux-tools-common 4.15.0-47.50 from bionic-proposed and
checked that the new /usr/bin/perf binary still doesn't demangle C++
symbols (even when "perf report --demangle" is passed explicitly).

I was wrong. `/usr/bin/perf` is just a shell script calling a kernel specific
version.
The real executable is in `linux-hwe-tools-4.**`.
I checked the source of `linux-hwe-tools-4.15.0-36` and it already has the
necessary fix.
Rebuilding just the perf executable from withhin the source dir
I checked this issue again, because it is really anoying.
The fix is already present in HWE kernel source.

However perf (`/usr/bin/perf`) is comming from linux-tools-common package
Found the relevant commit that needs to get ported.

Will this fix be available in bionic (18.04) as well? I've recently
tried installing perf from apt-get and symbol demangling still does not
work.
