Subject: [PATCH 08/28] qapi: Support flat unions tag values with leading digit
Date: Tue, 23 Mar 2021 10:40:05 +0100 [thread overview]
Message-ID: <20210323094025.3569441-9-armbru@redhat.com> (raw)
In-Reply-To: <20210323094025.3569441-1-armbru@redhat.com>
Flat union tag values get checked twice: as enum member name, and as
union branch name. The former accepts leading digits, the latter
doesn't. The restriction feels arbitrary. Skip the latter check.
This can expose c_name() to input it can't handle: a name starting
with a digit. Improve it to return a valid C identifier for any
input.
