[Linux 4.8.6] New perf script output format about flamegraph HOT 5 CLOSED

I too have this issue, I've fixed it with a patch, though arguably I could be applying it in the wrong place (the original regex the match happens on could be written so that the +0xaddress doesn't get captured)

See my pull request:
#114

ok, sorry, I need to catch up with the PRs.

It may make more sense to modify the regex to have an optional capture group (not sure if perl regexes support this or not). Otherwise just adding it to the match expression means it will fail on older kernels. Or you could just do what I did inside the if expression with another regex inside.

Just full disclosure, I don't know a lick of perl, I figured out how to do what I did by googling things.

I also faced the same issue with perf script output in version 4.8.6. I'm using Ubuntu and the kernel version is 4.8.0-30-generic.

As a temporary workaround, I used sed to remove the hexadecimal part in the function.

sudo perf script | sed -r 's/\+0x[a-f0-9]+//' > out.stacks

Thanks, should be fixed now with my latest pushes. Importantly, it passes the bundled tests, which cover older kernels.
