sunperf in ss12u1: dalign or xmemalign ? and -native and xarch?

807736Jan 14 2010 — edited Jan 14 2010
hello all,
i read in the the document ( [1.5 Getting Started With Sun Performance Library|http://docs.sun.com/source/821-0276/plug_intro.html#0_pgfId-13261] ) :
they talk about -dalign for fortran and -xmemalign for cc or CC, but xmemalign doesn't seem to exist. 
nemo-henry% cc -xmemalign=8s toto-mem.c -xlic_lib=sunperf
cc: Warning: Option xmemalign=8s is not available on x86/x64 Solaris platform, ignored
Is it normal? What i have to use on x86/x64 platforms?

My second question is about -native and -xarch?
If i prefer performance, is it better to use: 
-native
or 
-xarch=sse3
(on sun x2270)

Or are they the same option?

thanks in advance for help,

gerard
