Should be "XL", see Modules/CMakeCCompilerId.c.in, there they are all defined.
You can also see this here in the output from the cmake run:

[cmake-developers] Test for compiler flags ineffective with xlc?

2011-08-11 Thread Stephen Kelly 

Hi,

In this build log the test for -fvisibility=hidden results in success, but 
when the flag is used it fails:

http://www.cdash.org/CDash/testDetails.php?test=109109951&build=1419259

I'm guessing that compiler treats -f as a filename for some reason. Can 
anything be done about that? Should I just exclude that platform from 
performing the test? How? Would if (${CMAKE_CXX_COMPILER_ID} MATCHES xlC) 
match?

Thanks,

Steve.
