9808 /* Some instructions can be left alone too. Unconditional
9809 branches, except for bcctr with BO=0x14 (bctr, bctrl),
9810 avoid the icache failure.
9811
9812 The problem occurs due to prefetch across a page boundary
9813 where stale instructions can be fetched from the next
9814 page, and the mechanism for flushing these bad
9815 instructions fails under certain circumstances. The
9816 unconditional branches:
9817 1) Branch: b, bl, ba, bla,
9818 2) Branch Conditional: bc, bca, bcl, bcla,
9819 3) Branch Conditional to Link Register: bclr, bclrl,
9820 where (2) and (3) have BO=0x14 making them unconditional,
9821 prevent the bad prefetch because the prefetch itself is
9822 affected by these instructions. This happens even if the
9823 instruction is not executed.
9824
9825 A bctr example:
9826 .
9827 . lis 9,new_page@ha
9828 . addi 9,9,new_page@l
9829 . mtctr 9
9830 . bctr
9831 . nop
9832 . nop
9833 . new_page:
9834 .
9835 The bctr is not predicted taken due to ctr not being
9836 ready, so prefetch continues on past the bctr into the
9837 new page which might have stale instructions. If they
9838 fail to be flushed, then they will be executed after the
9839 bctr executes. Either of the following modifications
9840 prevent the bad prefetch from happening in the first
9841 place:
9842 .
1b786873
L
9843 . lis 9,new_page@ha lis 9,new_page@ha
9844 . addi 9,9,new_page@l addi 9,9,new_page@l
