[PATCH][PR tree-optimization/68198] Avoid CFG explosion due to threading
PR tree-optimization/68198
* tree-ssa-threadupdate.c (valid_jump_thread_path): Distinguish
between threading a multi-way branch and a thread path that contains
a multi-way branch. Disallow the case where a path contains a
multi-way branch and does not thread a multi-way branch.
(thread_through_all_blocks): Update comment.
PR tree-optimization/68198
* gcc.dg/tree-ssa/pr66752-3.c: Update expected output for VRP1.
* gcc.dg/tree-ssa/pr68198.c: New test.
