- * Delay slots on QEMU/CRIS.

- * If an exception hits on a delayslot, the core will let ERP (the Exception
- * Return Pointer) point to the branch (the previous) insn and set the lsb to
- * to give SW a hint that the exception actually hit on the dslot.
- *
- * CRIS expects all PC addresses to be 16-bit aligned. The lsb is ignored by
- * the core and any jmp to an odd addresses will mask off that lsb. It is
- * simply there to let sw know there was an exception on a dslot.
- *
- * When the software returns from an exception, the branch will re-execute.
- * On QEMU care needs to be taken when a branch+delayslot sequence is broken
- * and the branch and delayslot dont share pages.
- *
- * The TB contaning the branch insn will set up env->btarget and evaluate
- * env->btaken. When the translation loop exits we will note that the branch
- * sequence is broken and let env->dslot be the size of the branch insn (those
- * vary in length).
- *
- * The TB contaning the delayslot will have the PC of its real insn (i.e no lsb
- * set). It will also expect to have env->dslot setup with the size of the
- * delay slot so that env->pc - env->dslot point to the branch insn. This TB
- * will execute the dslot and take the branch, either to btarget or just one
- * insn ahead.
- *
- * When exceptions occur, we check for env->dslot in do_interrupt to detect
- * broken branch sequences and setup $erp accordingly (i.e let it point to the
- * branch and set lsb). Then env->dslot gets cleared so that the exception
- * handler can enter. When returning from exceptions (jump $erp) the lsb gets
- * masked off and we will reexecute the branch insn.
