Detect symbols generated by the OCaml compiler based on their prefix. Demangle OCaml symbols, returning a newly allocated string (like the existing Java demangling functionality). Move a helper function (hex) from tests/code-reading.c to util/string.c To test: echo 'Printf.printf "%d\n" (Random.int 42)' > test.ml perf record ocamlopt.opt test.ml perf report -d ocamlopt.opt Signed-off-by: Fabian Hemmer <copy@copy.sh> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> LPU-Reference: 20210203211537.b25ytjb6dq5jfbwx@nyu Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
