I am not sure about this. There is an earlier if statement in the loop
that does a 'return' instead of a break (or continue) and there is a
return in the 'else' part of the if that sets must_annul. Both of these
are inside the loop that looks at all t

While doing more testing of the MIPS frame header optimization I checked
in earlier, I found I could not build the elf toolchain when I turned the
optimization on by default. This is because GCC was putting a frame related
instruction (the save of the return address) into an annulled delay slot.
