-xchip=c

Specify target processor for the optimizer.

    SPARC: 77/90 x86:77

This option specifies timing properties by specifying the target processor.

Although this option can be used alone, it is part of the expansion of the -xtarget option; it is provided to allow overriding a -xchip value implied by the a specific -xtarget option.

Some effects of -xchip=c are:
