tree-optimization/106249 - unroll-and-jam and LC SSA upate
When I delayed the LC SSA update in unroll-and-jam this exposed
an issue that tree_transform_and_unroll_loop does a full function
LC SSA verification when new_loop is NULL (when it doesn't need to
do versioning). That wasn't intended. I also took the chance
to make the versioning in tree_transform_and_unroll_loop use
TODO_update_ssa_nophi for the loop versioning SSA update which
I somehow missed earlier.
PR tree-optimization/106249
* tree-ssa-loop-manip.cc (tree_transform_and_unroll_loop):
Only verify LC SSA of the new_loop if we created it.
Use TODO_update_ssa_nophi for the SSA update after versioning
the loop.
* gcc.dg/pr106249.c: New testcase.
