--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> ---
-m64 requires 64-bit instructions.  We will ICE if we try to generate code
for -m64 without support for 64-bit insns enabled in the compiler.  For
example, the stdu insn is required to implement the ABI sanely.

If the user said they want a -mcpu=3D for a CPU that has no 64-bit insns,
but also wants to use -m64, we should just say sorry, that won't fly.=
