Should he search our docs for "which flags does PHP set by default for suncc?" Being slightly more verbose in the NEWS isn't a bad thing - and if this is something "important" then you should document it too. -Hannes -- PHP CVS Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

(David Soria Parra) Thats great.. what are those default flags and "why should I care"? Hi Hannes, so the complete list is at http://docs.sun.com/app/docs/doc/819-5265/bjapp?a=view but let me get through the most important parts of the list: xtarget=native Causes to generate processor specific code. xalias_level=basic does optimization based on basic assumptions about the c types e.g. float* will not point to int*. fsimple=2 will simplify floating point arithmetic xipo=1 will do an analysis of all object files and try to optimize across all object files. xlibmopt optimize math routines, according to the documentation this might result in slight differences to the std math lib. But I asked some sun engineers and it was considered safe. So actually I picked options that usually are set by the -fast option, but removed the onces that might cause problems. That's why the list is that long and that's even why I don't use -xO5 but -xO4 to not run in errors (this was recommand by some webstack guy). The only sad thing is that you still need to set the compiler using the CC env variable as by default we are looking for gcc and ignoring other compilers even though they are the default cc compiler on those machines. I acutally think that this is not desirable. David -- PHP CVS Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
