If gcc just emits

IIRC, that's exactly what GCC will emit if you don't tell it to try to
fill delay slots.  If it tries to fill delay slots and fails, I doubt
the assembler is going to succeed at that.

Is that a way to tell gcc not to fill the delay slots with nop? If gcc
has nothing else to fill, do nothing and let gas do its thing.

Read mips_output_conditional_branch ()

That part I'm familiar with.  The part I'm not familiar with is
whether this would trigger problems in say the SGI assembler, or
whether such reordering of .sets would violate some MIPS assembler
specification I'm not familiar with.
