We (for some value of we, as an ex-employee for several years now) should have done this years ago.
If there is a need to be completely generic (exactly which shipping systems in the last 5 years weren't ultra compatible) the appropriate logic can be put into a .so file and automatically selected either at runtime or installation time (the former is usually the right approach, so that a network leveraged binary can work well with whatever client connects up). -----Original Message----- From: [email protected] [mailto:tools-compilers-bounces at opensolaris.org] On Behalf Of Sriram Natarajan Sent: Thursday, January 21, 2010 2:23 PM To: tools-compilers at opensolaris.org Subject: [tools-compilers] Using -xtarget=ultra2 Hi I maintain php within OpenSolaris and Web Stack PHP for Solaris 10. We compile this open source application with Sun Studio 12 Update 1 compiler. While measuring performance on SPARC, I noticed that there are performance to gain (around 10%) by using -xtarget=ultra2 rather than the current -xtarget=v8 that we use right now. I am wondering, if you have any insights and any caveats to be aware of on enabling such option for Web Stack PHP (which is unbundled and available for download version from Sun.com/webstack) thanks - Sriram -- This message posted from opensolaris.org _______________________________________________ tools-compilers mailing list tools-compilers at opensolaris.org ---------------------------------------------------------------------- The information contained in this transmission may be confidential.
