Hi, Not sure the optimization flags are good in : http:// mercurial.opensound.com/?rev/a15da9411856 As I understand "-fast" is a macro equivalent to several others flags: http://developers.sun.com/solaris/articles/options.html http://developers.sun.com/solaris/articles/amd64_migration.html#fast so using -xO2 and -fast at the same does not make much sense AFAICS Note also that -fast will produce target platform specific code (in the "Cons" section : The -fast option lets the compiler assume that the target platform the code will run on is the same platform on which it was compiled (because it includes -xtarget=native)) So it has to be used with care.
