Subject: [PATCH v6 2/3] perf tools: Add lexical definition of event name
Date: Fri, 12 Feb 2021 18:03:17 +0900 [thread overview]
Message-ID: <20210212090318.1522292-3-nakamura.shun@jp.fujitsu.com> (raw)
In-Reply-To: <20210212090318.1522292-1-nakamura.shun@jp.fujitsu.com>
Add the lexical definition of event name so that the numbers are recognizable.
A64FX defines an event name that starts with a number.
