Subject: [Bug middle-end/38474] slow compilation at -O0 (callgraph optimization, inline heuristics, expand )
Date: Tue, 16 Dec 2008 16:28:00 -0000	[thread overview]
Message-ID: <20081216162646.30240.qmail@sourceware.org> (raw)

------- Comment #26 from steven at gcc dot gnu dot org  2008-12-16 16:26 -------
I am going to work on the -O0 problems a bit.

The operand scanner is the problem at -O3. Richi, this is one you may want to
try on the alias improvements branch, if most of the time is spent on virtual
SSA names (I haven't checked, but it's likely with so many aggregate-typed
variables).
