Subject: [Bug tree-optimization/45178] CDDCE doesn't eliminate conditional code in infinite loop
Date: Wed, 04 Aug 2010 13:05:00 -0000 [thread overview]
Message-ID: <20100804130502.3118.qmail@sourceware.org> (raw)

Subject: Re: New: CDDCE doesn't eliminate
conditional code in infinite loop
Hmm, so the problem is that we produce two alternating loops and both with
unknown number of iterations?
We might teach loop discovery to preffer single infinite loop over alternation
I guess.
