Hi Marc,

Take a look here for some documentation: http://pic.dhe.ibm.com/infocenter/compbg/v121v141/index.jsp

Specifically take a look at:

(1) [XL C/C++ Compiler for Blue Gene/Q V12.1] => [Compiler Reference] => [Compiler Predefined Macros]

(2) [XL C/C++ Compiler for Blue Gene/Q V12.1] => [Compiler Reference] => [Compiler built-in functions]

That's the documentation I used.

Hope this helps.

Best,

George

Attached is the modified Mpzf header and a patch in case others find useful.

I am having trouble finding this information on IBM's website: what compilers define the macro __xlC__ exactly? And do they all support the __cnt[lt]z8 builtins? I would assume the linux and aix versions are fine (32 bit mode has already been excluded by the GMP test), but I am wondering about the z/OS or z/VM version.

I am also thinking of adding something like the attached patch so XL C++ is not too penalized compared to g++, but again I am not sure what macros I should check.

Since I doubt anyone wants to run CGAL on a mainframe I'll probably just go with __xlC__, but if you know the answer...
