perf tools: Preserve identifier id in OCaml demangler

2021-03-30T15:45:59Z

Some OCaml developers reported that this bit of information is sometimes useful for disambiguating functions for which the OCaml compiler assigns the same name, e.g. nested or inlined functions.

perf tools: Add OCaml demangling

2021-02-17T18:15:06Z

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 Acked-by: Namhyung Kim Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Mark Rutland Cc: Peter Zijlstra LPU-Reference: 20210203211537.b25ytjb6dq5jfbwx@nyu Signed-off-by: Arnaldo Carvalho de Melo
