If you use `perf report` then that currently is impossible I guess. But 
if you use flamegraph for example then ddemangle can help here:
```
git clone https://github.com/brendangregg/FlameGraph.git
perf script | FlameGraph/stackcollapse-perf.pl | 
FlameGraph/flamegraph.pl | ddemangle > perf.svg
```

but some symbols remain mangled
