…n MIPS Modify: Add a global variable 'CurForbiddenSlotAttr' to save current instruction's forbidden slot and whether set reorder. This is the judgment condition for whether to add nop. We would add a couple of '.set noreorder' and '.set reorder' to wrap the current instruction and the next instruction. Then we can get previous instruction`s forbidden slot attribute and whether set reorder by 'CurForbiddenSlotAttr'. If previous instruction has forbidden slot and .set reorder is active and current instruction is CTI. Then emit a NOP after it. Fix https://github.com/llvm/llvm-project/issues/61045. Because https://reviews.llvm.org/D158589 was 'Needs Review' state, not ending, so we commit pull request again. (cherry picked from commit 96abee5eef31274415681018553e1d4a16dc16c9)
