There was one gcc bug[1] that I fixed but the rest are cases that gcc cannot detect due to the point at which it does the fallthrough check. Most of this patch adds __builtin_unreachable() hints in places that throw this warning to indicate to gcc that the fallthrough will never happen. The remaining cases are actually possible fallthroughs due to incorrect code running on the simulator; in which case an Unknown instruction is returned.

There is already a GCC fix [1] submitted for review but, until it is merged into GCC trunk, GEM5 will not build with GCC 7 due to these fallthrough warnings. This patch silences the spurious fallthrough warn |
