Subject: [PATCH v1] perf jevents: Fix build issue in '*/' in event descriptions
Date: Wed, 13 Nov 2024 08:55:58 -0800	[thread overview]
Message-ID: <20241113165558.628856-1-irogers@google.com> (raw)

For big string offsets we output comments for what string the offset
is for. If the string contains a '*/' as seen in Intel Arrowlake event
descriptions, then this causes C parsing issues for the generated
pmu-events.c. Catch such '*/' values and escape to avoid this.
