Documented in the Sun Studio cc man page:
Predefinitions:unix
sparc (SPARC)
i386 (x86)
sun
The above are not predefined in -Xc mode.
These predefinitions are valid in all modes:
__amd64(x86)
__x86_64(x86)
__sun
__unix
__SUNPRO_C=0x580
__`uname -s`_`uname -r`
__sparc (SPARC)
__sparcv9 (SPARC with -xarch=v9|v9a|v9b)
__i386 (x86)
__BUILTIN_VA_ARG_INCR
__SVR4
