Sun WorkShop Compiler C 5.0 User's Guide

-xchip=c

Specifies the target processor for use by the optimizer.

c must be one of the following: generic, old, super, super2, micro, micro2, hyper, hyper2, powerup, ultra, ultra2, ultra2i, 386,486, pentium, pentium_pro, 603, 604.

Although this option can be used alone, it is part of the expansion of the -xtarget option; its primary use is to override a value supplied by the -xtarget option.

This option specifies timing properties by specifying the target processor.

Some effects are:

Table 2-3 The -xchip Values

Value 

Meaning 
 generic

Use timing properties for good performance on most x86 and SPARC architectures. 

 

This is the default value that directs the compiler to use the best timing properties for good performance on most processors, without major performance degradation on any of them.  
 old

Uses timing properties of pre-SuperSPARC(TM) processors. 
 super

Uses timing properties of the SuperSPARC chip. 
 super2

Uses timing properties of the SuperSPARC II chip. 
 micro

Uses timing properties of the microSPARC chip. 
 micro2

Uses timing properties of the microSPARC II chip. 
 hyper

Uses timing properties of the hyperSPARC(TM) chip. 
 hyper2

Uses timing properties of the hyperSPARC II chip. 
 powerup

Uses timing properties of the Weitek® PowerUp(TM) chip.
 ultra

Uses timing properties of the UltraSPARC® chip.
 ultra2

Uses timing properties of the UltraSPARC II® chip.
 ultra2i

Uses timing properties of the UltraSPARC IIi® chip.
 386

Uses timing properties of the Intel 386 architecture. 
 486

Uses timing properties of the Intel 486 architecture 
 pentium

Uses timing properties of the Intel pentium architecture 
 pentium_pro
