I know, but they still have code that supports i386 and they follow the same API's as gcc... So they are 1/2 broken: http://nxr.netbsd.org/xref/src/external/bsd/llvm/dist/clang/lib/Headers/cpuid.h#184 The check for level is missing here: http://nxr.netbsd.org/xref/src/external/bsd/llvm/dist/clang/lib/Headers/cpuid.h#177 And the bug report for gcc: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68491 christos
