Subject: [PATCH 03/27] Don't allow NULL as an argument to block_scope
Date: Fri, 20 Jan 2023 14:45:54 -0700 [thread overview]
Message-ID: <20230120214618.3236224-4-tom@tromey.com> (raw)
In-Reply-To: <20230120214618.3236224-1-tom@tromey.com>
block_scope has special behavior when the block is NULL.
Remove this and patch up the callers instead.
