Where can I find the right doc for SunStudio For Linux ?

Question

I can find the docs for SunStudio here, http://docs.sun.com/app/docs/doc/819-5265/6n7c29ck9?a=view
but it seems that it doesn't right on linux platform.
#include <stdio.h>
int main(void)
#if defined(sun)
        printf("sun defined \n");
#else
        printf("sun undefined \n");
#endif
#if defined(unix)
        printf("unix defined \n");
#else
        printf("unix undefined \n");
#endif
#if defined(sparc)
        printf("sparc defined \n");
#else
        printf("sparc undefined \n");
#endif
#if defined(i386)
        printf("i386 defined \n");
#else
        printf("i386 undefined \n");
#endif
#if defined(__sun)
        printf("__sun defined \n");
#else
        printf("__sun undefined \n");
#endif
#if defined(__unix)
        printf("__unix defined \n");
#else
        printf("__unix undefined \n");
#endif
#if defined(__SUNPRO_C)
        printf("__SUNPRO_C defined \n");
#else
        printf("__SUNPRO_C undefined \n");
#endif
#if defined(__sparc)
        printf("__sparc defined \n");
#else
        printf("__sparc undefined \n");
#endif
#if defined(__i386)
        printf("__i386 defined \n");
#else
        printf("__i386 undefined \n");
#endif
#if defined(__SVR4)
        printf("__SVR4 defined \n");
#else
        printf("__SVR4 undefined \n");
#endif
        return 0;

Answer 1

You can refer to cc man pages. Here is about predefinitions:
Predefinitions:unix
sparc (SPARC)
i386 (x86)
sun
The above are not predefined in -Xc mode.
These predefinitions are valid in all modes:
__BUILTIN_VA_ARG_INCR
__SUNPRO_C=0x590
__SVR4(SPARC)
__SunOS(Solaris)
__SunOS_OSN.N(Solaris)
__amd64(x86 with-m64)
__gnu__linux(linux)
__i386(x86)
__linux(linux)
__linux__(linux)
__sparc(SPARC)
__sparcv9(with-m64)
__sun(Solaris)
__unix
__�uname -s�_�uname -r�
__x86_64(x86)
linux(x86,linux)
The following is predefined in -Xa and -Xt modes only:
__RESTRICT
The compiler also predefines the object-like macro
__PRAGMA_REDEFINE_EXTNAME,
to indicate the pragma will be recognized.
