Subject: Re: -ffast-math and floating point reordering
Date: Thu, 25 Mar 2004 18:46:00 -0000	[thread overview]
Message-ID: <02BFC253-7E86-11D8-8C7F-000A95D7CD40@apple.com> (raw)

One point I haven't seen yet:
A couple of strict-constructionists have asserted that people
who want reassociation done in a nonstandard way can easily rewrite 
their
code to achieve this.  This is not really true, because such expressions
often arise as a result of other optimizations, in a way that isn't 
obvious
from the source.  Offhand, inlining, unrolling, and constant/copy 
propagation
can all do it, and there are probably more.
