[Openmp-dev] OS definitions

Hi Jim,

Yes you are right - it should be included. I forgot to add it.


Thanks

Carlo,

I’m integrating the BGQ stuff into the code we’re getting ready to push,
and I have a question…
In kmp_os.h there’s this code


/* ---------------------- Operating system recognition -------------------
*/

#define KMP_OS_LINUX    0
#define KMP_OS_FREEBSD  0
#define KMP_OS_DARWIN   0
#define KMP_OS_FREEBSD  0
#define KMP_OS_WINDOWS  0
#define KMP_OS_CNK      0
#define KMP_OS_UNIX     0  /* disjunction of KMP_OS_LINUX, KMP_OS_DARWIN
etc. */

#define KMP_ARCH_X86        0
#define KMP_ARCH_X86_64     0
#define KMP_ARCH_PPC64      0

#ifdef _WIN32
# undef KMP_OS_WINDOWS
# define KMP_OS_WINDOWS 1
#endif

#if ( defined __APPLE__ && defined __MACH__ )
# undef KMP_OS_DARWIN
# define KMP_OS_DARWIN 1
#endif

// in some ppc64 linux installations, only the second condition is met
#if ( defined __linux )
# undef KMP_OS_LINUX
# define KMP_OS_LINUX 1
#elif ( defined __linux__)
# undef KMP_OS_LINUX
# define KMP_OS_LINUX 1
#else
#endif

#if ( defined __FreeBSD__ )
# undef KMP_OS_FREEBSD
# define KMP_OS_FREEBSD 1
#endif

#if ( defined __bgq__ )
# undef KMP_OS_CNK
# define KMP_OS_CNK 1
#endif

#if (1 != KMP_OS_LINUX + KMP_OS_FREEBSD + KMP_OS_DARWIN + KMP_OS_WINDOWS)
# error Unknown OS
#endif

Shouldn’t that last test also include KMP_OS_CNK? Or does CNK pretend to be
one of the other OSes as well?
