From: Thomas Huth <th...@redhat.com> Clang v7.0.1 does not like the __int128 variable type for inline assembly on s390x:
In file included from fpu/softfloat.c:97: include/fpu/softfloat-macros.h:647:9: error: inline asm error: This value type register class is not natively supported! asm("dlgr %0, %1" : "+r"(n) : "r"(d)); ^ Disable this code part there now when compiling with Clang, so that the generic code gets used instead.
