One more remark: I was not able to reproduce this behaviour with compact
branches, but it is possible that in some cases Gas' rewrite machinery
might actually move a previous instruction past the branch instead of
inserting a nop. That would in fact be incorrect code with compact
branches.
For example (using a traditional MIPS branch with delay slot) this:
addu $10, $11, $12
beq $13, $14, foo
may turn into:
0: 11aeffff beq $13,$14,0x0
4: 016c5021 addu $10,$11,$12
If that happened with compact branches it would be a disaster.
