Hello,Trying to understand if Sun Studio 11 or Studio 12 have any SPARC64 VI-specific compiler flags. Thanks in advance,Isaac

Hi,
Studio 12 has specific flags for SPARC64 VI. Studio 11 does not.
The flag you want is :
-xtarget=sparc64vi
Also if you want to use the fused multiply-add instructions, say :
-fma=fused
This can greatly help floating point performance. Also, Sun Performance Library
has been tuned for this chip.
