* jump.c (mark_all_labels): Work in cfglayout mode.
* cfgcleanup.c (cleanup_cfg): Do not call delete_dead_jumptables when in cfglayout mode, because there are no dead jumptables visible. * cfgrtl.c (commit_one_edge_insertion): Don't set bb->aux when in cfglayout mode. (commit_edge_insertions): Do not allow insertion of instructions with control flow insns when in cfglayout mode. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@119191 138bc75d-0d04-0410-961f-82ee72b054a4
