This broke when upgrading the minimal version # of GCC required to build the kernel, to a version above what ICC and # Clang claim to be. # # Rather than always including compiler-gcc.h then undefining or # redefining macros in compiler-intel.h or compiler-clang.h, let's # separate out the compiler specific macro definitions into mutually # exclusive headers, do more proper compiler detection, and keep shared # definitions in compiler_types.h. # # Fixes: cafa0010cd51 ("Raise the minimum required gcc version to 4.6") # Reported-by: Masahiro Yamada # Suggested-by: Eli Friedman #
