Subject: [Bug tree-optimization/26854] Inordinate compile times on large routines
Date: Wed, 14 Nov 2007 12:40:00 -0000 [thread overview]
Message-ID: <20071114124009.2058.qmail@sourceware.org> (raw)
In-Reply-To: <bug-26854-271@http.gcc.gnu.org/bugzilla/>
------- Comment #29 from lucier at math dot purdue dot edu 2007-11-14 12:40 -------
Subject: Re: Inordinate compile times on large routines
It appears to me from the raw logs at
http://www.suse.de/~gcctest/c++bench/random/
that all runs except for the -O0 fail with an out-of-memory failure,
so I don't know what this is really testing.
Relevant excerpt from the logs follows.
