Subject: [PATCH v1 6/6] perf test demangle-ocaml: Switch to using dso__demangle_sym
Date: Tue, 29 Apr 2025 11:58:38 -0700	[thread overview]
Message-ID: <20250429185839.1807005-7-irogers@google.com> (raw)
In-Reply-To: <20250429185839.1807005-1-irogers@google.com>

The use of the demangle-ocaml APIs means we don't detect if a different
demangler is used before the OCaml one for the case that matters to
perf.
