It fixes up the edges and jumps on those edges, but when after reorder blocks and in rtl (non-cfglayout) mode that is clearly not enough, because it keeps the block order the same and so we can end up with more than 1 hot/cold section transition in the same function. So, this patch fixes that up too. 2021-03-03 Jakub Jelinek <ja...@redhat.com> PR target/99085 * cfgrtl.c (fixup_partitions): When changing some bbs from hot to cold partitions, if in non-layout mode after reorder_blocks also move affected blocks to ensure a single partition transition. * gcc.dg/graphite/pr99085.c: New test.
