The old boogyman was "is there any other SPARC processor" which didn't support the extensions. Presumably that would be certain era Fujitsu processors, an IEEE processor spec from the EU space program, and who knows what else.
Translation: what Alan said, just optimize the hell out of it. If someone eventually really finds a processor which can't hack it, handle it as a special case. -----Original Message----- From: [email protected] [mailto:tools-compilers-bounces at opensolaris.org] On Behalf Of Alan Coopersmith Sent: Thursday, January 21, 2010 3:05 PM To: Darryl Gove Cc: Sriram Natarajan; tools-compilers at opensolaris.org Subject: Re: [tools-compilers] Using -xtarget=ultra2 Darryl Gove wrote: > Anyway, in terms of downsides a binary compiled to use v8plus will not > run on any pre-UltraSPARC processors.
