This ties in with the other delay slot issues such as issue #330 for mips and so should be considered when implementing their fix.. I have come across another related issue to the mips branch delay problems. It may be considered that this is just how unicorn works with regards to delay slots.

MIPS branch delay slot question ? I removed MIPS's branch delay slot support in my core. I wrote my own assembler for it. But now I decide to switch to gnu tools. So my question is if there is a compiliation switch in gcc to turn off " mips's branch delay slot" when generate binary image? If No, is it pretty easy to modify assembler... Simon Dardis - [PATCH, Mips] Compact branch/delay slot… Undo delay slot scheduling if an orphaned high-part relocation is in a delay slot and use a compact branch is used instead. Undo delay slot scheduling in the case where a forbidden slot hazard is immediately followed by a delay slot branch. This would cause a nop to be inserted otherwise.

CS252 S05 CMSC 411 - 5 (from Patterson) 9 Scheduling Branch Delay Slots • A is the best choice, fills delay slot & reduces instruction count (IC) • In B, the sub instruction may need to be copied, increasing IC • In B and C, must be okay to execute sub when branch fails add R1,R2,R3 if R2=0 then delay slot A. From before branch B. From branch target C. Exceptions and Interrupts for the MIPS architecture
