Subject: [Bug bootstrap/44470] [4.6 Regression] Failed to bootstrap with - -with-arch=atom
Date: Mon, 16 Aug 2010 23:50:00 -0000 [thread overview]
Message-ID: <20100816234957.3442.qmail@sourceware.org> (raw)
In-Reply-To: <bug-44470-682@http.gcc.gnu.org/bugzilla/>
------- Comment #18 from bernds at gcc dot gnu dot org 2010-08-16 23:49 -------
I'm seeing some strange situations where this code is unnecessarily producing
lea insns even when not tuning for Atom.
This code looks very strange. I don't understand why we aren't splitting to a
lea pattern anymore if we want to produce a lea insn.
Also, isn't the test for TARGET_OPT_AGU reversed?
