Subject: [Bug middle-end/33349] Redundant zero-extension of registers
Date: Fri, 06 Feb 2009 21:45:00 -0000	[thread overview]
Message-ID: <20090206214516.30683.qmail@sourceware.org> (raw)
In-Reply-To: <bug-33349-8549@http.gcc.gnu.org/bugzilla/>



------- Comment #1 from steven at gcc dot gnu dot org  2009-02-06 21:45 -------
This would be fixed if someone would fix the Sign Extension Elimination pass
(yes, it also handles zero extensions).  But that pass is probably broken
beyond repair at this point, and likely needs a rewrite instead of just a fix.
