-xspace
(Solaris 2.x only) The -xspace option does no optimizations that increase the
code size.
Example: Do not unroll loops.
-xtarget= t
(Solaris 2.x only) The -xtarget= t option specifies the target system for the
instruction set and optimization.
t must be one of: native , generic , system-name.
The -xtarget option permits a quick and easy specification of the -xarch ,
-xchip , and -xcache combinations that occur on real systems. The only
meaning of -xtarget is in its expansion.
The performance of some programs may benefit by providing the compiler
with an accurate description of the target computer hardware. When program
performance is critical, the proper specification of the target hardware could be
Table 3-8 The -xtarget Values
Value Meaning
native Get the best performance on the host system.
The compiler generates code for the best performance on the host
system. It determines the available architecture, chip, and cache
properties of the machine on which the compiler is running.
generic Get the best performance for generic architecture, chip, and cache.
The compiler expands -xtarget=generic to:
-xarch=generic -xchip=generic -xcache=generic
This is the default value.
system-name Get the best performance for the specified system.
You select a system name from Table 3-9 that lists the mnemonic
encodings of the actual system names and numbers.
