(unloop): Likewise. (remove_path): Update. (fix_loop_placements): Update. * tree-ssa-loop-ivcanon.c (try_unroll_loop_completely): Add loop_closed_ssa_invalidated parameter; pass it around. (canonicalize_loop_induction_variables): Update loop closed SSA form if needed. (tree_unroll_loops_completely): Likewise; do irred update out of the outer loop; verify that SSA form is closed. * cfgloop.h (unrloop): Update. * gfortran.dg/pr54967.f90: New testcase.
