3.4.121 –xchip=c

Specify target processor for the optimizer.

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:

• Instruction scheduling

• The way branches are compiled

• Choice between semantically equivalent alternatives

The following tables list the valid -xchip processor name values:

Table 3–15 Common –xchip SPARC Processor Names

-xchip=	Optimize for:
generic	most SPARC processors. (This is the default.)
native	this host platform.
sparc64vi	SPARC64 VI processor
ultra	UltraSPARC processor.
ultra2	UltraSPARC II processor.
ultra2e	UltraSPARC IIe processor.
ultra2i	UltraSPARC IIi processor.
ultra3	UltraSPARC III processor.
ultra3cu	UltraSPARC IIIcu processor.
ultra3i	UltraSPARC IIIi processor
ultra4	UltraSPARC IV processor
ultra4plus	UltraSPARC IV+ processor
ultraT1	UltraSPARC T1 processor
ultraT2	UltraSPARC T2 processor

On x86 platforms: the -xchip values are pentium, pentium_pro, pentium3, pentium4, generic, opteron, and native.
