Subject: making double type default to 80 or 128 bytes
Date: Fri, 7 Aug 2020 07:59:58 -0700	[thread overview]
Message-ID: <ddf4798f-620e-531e-8bce-b31a08dedb2a@gmail.com> (raw)


Is it possible to modify the gcc compiler so that recompiling existing 
code and libraries will produce longer doubles (80 or 128 bytes)

without having to re declare all the double types.  This may be a stupid 
question but I'm looking for a quick fix to see if extra

precision helps with an optimization problem. Thanks.
