When collecting perf samples, like so:
`perf record --latency --call-graph=dwarf --output=/tmp/perf.data <some-binary>`
There are config errors with llvm-addr2line that don't appear to be present with the gnu addr2line:
`addr2line_configure /location/of/elf: addr2line configuration failed`
perf appears to be invoking addr2line like so according to `ps aux`:
`addr2line -e /location/of/elf -a -i -f`
It's possible that something changed in the hwe kernel's perf.
My setup:
Ubuntu 24.04
kernel: 6.17.0-14-generic
perf: 6.17.9
llvm-addr2line: Ubuntu LLVM version 21.1.8 (from apt repository)
