Subject: [Bug tree-optimization/63169] ivopts rewrite_uses pessimizes debug info
Date: Thu, 04 Sep 2014 14:31:00 -0000	[thread overview]
Message-ID: <bug-63169-4-bjGdSNYGoI@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
IVOPTs depends on CSE to remove the effect of building its (sometimes gigantic)
GENERIC expressions figuring out IVs and inserting them multiple times.

Not sure if we even try to optimize the IV chosen to replace debuginfo uses.
