Ok,
When given:
N+0: branch foo
N+2: nop
PC=N (or N+1)
SPC=N+2
would this result in a double single-step leaving PC==foo? If it does
then you've at least got STEP_SKIPS_DELAY like behavior.
Actually, both when PC=N (at the branch instruction) and when PC=N+1 (in
the delay slot) a *single* single-step will leave us at PC==foo - the
single-step exception fires after the instruction pointed out by SPC has
been executed.
I'll go and have a closer look at STEP_SKIPS_DELAY.
