-xcache=c

(Solaris 2.x only) The -xcache=coption defines the cache properties for use by the optimizer.

c must be one of the following:

•generic

•s1/l1/a1

•s1/l1/a1:s2/l2/a2

•s1/l1/a1:s2/l2/a2:s3/l3/a3

The si/li/ai are defined as follows:

 

si

The size of the data cache at level i, in kilobytes

 

li

The line size of the data cache at level i, in bytes

 

ai

The associativity of the data cache at level i

 

Although this option can be used alone, it is part of the expansion of the -

 

target

option; its primary use is to override a value supplied by the -

 

target option.

 

This option specifies the cache properties that the optimizer can use. It does not

 

guarantee that any particular cache property is used.

Value

Meaning

 

 

 

generic

Define the cache properties for good performance on most SPARCs.

 

This is the default value which directs the compiler to use cache properties for good

 

performance on most SPARC processors, without major performance degradation on any

 

of them.

 

 

With each new release, these best timing properties will be adjusted, if appropriate.

 

 

s1/l1/a1

Define level 1 cache properties.

 

 

s1/l1/a1:s2/l2/a2

Define levels 1 and 2 cache properties.

 

 

 

s1/l1/a1:s2/l2/a2:s3/l3/a3 Define levels 1, 2, and 3 cache properties
