Subject: Re: [LTO][PATCH] Fix long double precision problem
Date: Mon, 17 Dec 2007 21:53:00 -0000	[thread overview]
Message-ID: <498552560712171318o3da22bcn8142a995111732b4@mail.gmail.com> (raw)
In-Reply-To: <4765FBC0.8020400@codesourcery.com>

Would that easier and less error prone if we just emit the precision?
I looked at the i386 and ia64 backend and found float types with
precisions 32, 64, 80, 82 and 128. I am not sure if there is an easy
way to do the search in an architecture-indepedent manner?
