-xcache= c
(Solaris 2.x only) The -xcache= c option 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:
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.
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
Table 3-4 The -xcache Values
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
