-xmaxopt[=n]

Enable optimization pragma and set maximum optimization level.

SPARC:77 x86:77

n has the value 1 through 5 and corresponds to the optimization levels of -O1 through -O5. If not specified, the compiler uses 5.

This option enables the C$PRAGMA SUN OPT=n directive when it appears in the source input. Without this option, the compiler treats these lines as comments.

If such a pragma directive appears with an optimization level greater than the maximum level on the -xmaxopt flag, the compiler uses -xmaxopt level.
