Luke Wren 2f6e98335f Add two new tests for IRQs-over-Zcmp, and fix a bug they found: ... Interrupting the PC-setting step of a cm.popret (only) can sample the return target as the exception return PC, which will cause the stack pointer adjust to be skipped when returning from the IRQ. Fix this by making the PC-setting step uninterruptible (note the PC-setting step is the instruction we execute first out of the group of instructions specified in the Zc spec as being atomic wrt interrupts. This does not itself imply that the PC-setting step is uninterruptible, it just requires that when the PC-setting step retires, all following steps also retire. However this is not sufficient given the special case logic that allows the jr ra PC-setting step to execute before the final stack adjust as an optimisation.)		2023-11-03 21:12:21 +00:00
