Generally speaking a MIPS assembler is free to do arbitrary reordering.
In the past there have been non-GNU assembler that were doing more massive
reordering than gcc does ... Using .set noreorder means you dump the
assembler's intelligence and take full responsibility for dealing with
all interlocks (or the lack thereof) and other performance issues
yourself.
