Hi! ----
Are there any known compiler bugs/issues in Sun Studio 11 x86 (cc -V == "cc: Sun C 5.8 Patch 121016-05 2007/01/10") which may cause an application to run slower with "-xc99=%all -xO4 -xalias_level=basic -xdepend" compared to "-xO3" (both builds use "-xspace -Xa -xstrconst" as additional build options) ? I did a small test with AST/ksh93 and got the following results for the following command: $ ksh93 -c 'float z=5; integer i=0 ; for((i=0 ; i < 10000000 ; i++ )) ; do (( z=sin(z) )) ; done ; print -- $z' # With "-xO3" it takes ~31 seconds to execute this script. With "-xc99=%all -xO4 -xalias_level=basic -xdepend" it takes ~39 seconds to execute this script. Erm... the results are somehow upside-down from what I would expect from these options... ;-( ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ tools-discuss mailing list [email protected]
