Subject: Re: [GCC 3.x] Performance testing for QA
Date: Tue, 03 Sep 2002 13:25:00 -0000 [thread overview]
Message-ID: <20020903202513.4ABABF2D4B@nile.gnat.com> (raw)
<<Since the benchmark gcc is never fed any erroneous source while running
the benchmark, none of the error-handling stuff is ever executed. With
profile-based optimization it's possible to move a lot of that stuff so
it never gets paged in; that's a significant win. The same conditions
don't apply when running gcc normally, so this is fairly artificial.
>>
Why would it be paged in if it is not executed?
