llvm's integrated assembler cannot handle immediate values which are calculated with two local labels: <instantiation>:3:13: error: invalid operand for instruction clgfi %r14,.Lsie_done - .Lsie_gmap Workaround this by adding clang specific code which reads the specific value from memory. Since this code is within the hot paths of the kernel and adds an additional memory reference, keep the original code, and add ifdef'ed code.
