3

Generates the highest level of optimization. Uses optimization algorithms that take more compilation time or that do not have as high a certainty of improving execution time. Optimization at this level is more likely to improve performance if it is done with profile feedback. See -xprofile=p.

If the optimizer runs out of memory, it tries to recover by retrying the current procedure at a lower level of optimization and resumes subsequent procedures at the original level specified in the command-line option.

-xpg

Same as -pand -pg

-xprofile=p

(Solaris 2.x only) The -xprofile=poption collects data for a profile or use a profile to optimize.

p must be collect, use[:name], or tcov.
