Solaris and Preprocessor Macros

问题


Would someone post the results of cpp -dM < /dev/null from a Solaris 10 or above system?

I'm having trouble locating what preprocessor macros are typically defined. Solaris documentation does not discuss it in detail [1], [2], and Google is not being very helpful.

Thanks in advance.

@jens:

Sparc systems from Solaris 10 onwards are always 64bit. X64 systems came in with Solaris 10, though you could still boot a 32bit x86 kernel.

$ isainfo
amd64 i386
$ isainfo -b
64
$ isainfo -v
    64-bit amd64 applications
        avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 
        sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu efs f16c rdrand 
    32-bit i386 applications
        avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 
        sse2 sse fxsr mmx cmov sep cx8 tsc fpu efs f16c rdrand 

/usr/bin/isainfo is your friend, from the command line.

From a programmatic point of view, examine the #defines in <sys/feature_tests.h>. You'll notice _LP64 ...
