Hi Paul, All
attached a little fix in clone asm code for SH to use a delayed branch
instead of a normal branch.
Let me know so I can commit it.
Regards,
Carmelo
A little optimization in clone sanity check: use a delayed branch
instruction (bt/s) so that null pointer check for second input
argument (hold on r5) is done into the delay slot.
