Subject: [PATCH] search_one_table()
Date: Tue, 13 Nov 2001 23:32:50 +0100 [thread overview]
Message-ID: <NDBBJMOHILCIIKFHCBHAIEOECAAA.per.persson@gnosjo.pp.se> (raw)
I found that gcc doesn't manage to do this rewrite itself. My micro-patch
saves a few bytes. Also the code becomes a little bit cleaner (IMHO).
Probably the same change could (and should) be made for the other
architectures too.
