Subject: [PATCH v1 2/5] perf dump-insn: Remove dump-insn.c
Date: Sat,  7 Feb 2026 00:24:25 -0800	[thread overview]
Message-ID: <20260207082428.1742209-3-irogers@google.com> (raw)
In-Reply-To: <20260207082428.1742209-1-irogers@google.com>

dump_insn and arch_is_uncond_branch are declared in
intel-pt-insn-decoder.c which is unconditionally part of all perf
builds. Don't declare weak versions of these symbols that will be unused.
