The above looks somewhat strange to me - why is there no `(inlined)` suffix visible anymore? Also, I can't test this patch locally, since - even without this patch - inline frame resolution with perf seems to be completely broken for me. It doesn't seem to be a perf regression - going back in time doesn't resole this - but rather of its dependencies or even of the DWARF emitted by the compilers I have available to test...
