Add a shell script to check that the call-graphs generated using frame pointers (--call-graph fp) are complete and not missing leaf functions: | $ perf test 88 -v | 88: Check Arm64 callgraphs are complete in fp mode : | --- start --- | test child forked, pid 8734 | + Compiling test program (/tmp/test_program.Cz3yL)... | + Recording (PID=8749)... | + Stopping perf-record... | test_program.Cz | 728 leaf | 753 parent | 76c main | test child finished with 0 | ---- end ---- | Check Arm SPE callgraphs are complete in fp mode: Ok It's supposed to work with both unwinders: | $ make # for libunwind (default) | $ make NO_LIBUNWIND=1 # for libdw Tester notes: Ran it on N1SDP and it passes, and it fails ifb9f6fbb3b2("perf arm64: Inject missing frames when using 'perf record --call-graph=fp'") isn't applied.
