Is "vendor=ibm" equivalent to "compiler=xlc"? The current vendor detection code looks for __xlC__ __IBMC__ and __IBMCPP__ before falling back to __AIX without __GNUC__. Can we pass -qhalt=e in all these cases? Or should we grep for xlc in the version output like [1] ? Brice
The observation that (__AIX && !__GNU__) -> vendor=ibm sounds like a safety net for unknown compilers. I think that since the current problem is specific to the Linux sched_setaffinity() probe, that ignoring that case is safe.
BTW: output of xlc when given no arguments is an entire manpage, not just the version info!
It occurs to me now that xlc MIGHT have an option to make only the specific (E) become fatal.
I will look and report back. -Paul -- Paul H. Hargrove phhargr...@lbl.gov Future Technologies Group HPC Research Department Tel: +1-510-495-2352 Lawrence Berkeley National Laboratory Fax: +1-510-486-6900
