Subject: What is -gtoggle useful for?
Date: Thu, 03 Sep 2009 15:08:00 -0000 [thread overview]
Message-ID: <b798aad50909030807w2d3ee64as9f0632326d482382@mail.gmail.com> (raw)
Alex,
With your VTA merge, you added the -gtoggle switch. I've read the
documentation for it and while I can parse what it says, I have no
idea what this flag is useful for. I've seen it used during
bootstraps and the documentation claims something about
-fcompare-debug. But I cannot imagine this being useful in general.
If it's really useful, could you add a rationale in the documentation?
If it's only useful for the very limited application of
-fcompare-debug, I'd say we should toss both out and make them
internal and/or --param. Anything that hides them from users.
In fact, it'd be nice to hide some other flags, but that's another problem.
Diego.
