That's only an advantage if you were previously using an MS compiler, 
though, since gcc has long provided code generation options for specific 
CPUs and CPU features, e.g.


Anyone benchmarked the change (if any) in Lua performance when using 
-mtune= to target the latest and greatest CPU when one is available?

Or done a VC6 versus VC8 benchmark? (We already have one report of VC9 <
