The following puts the logic into find_insert_point itself instead. 2022-04-06 Richard Biener <rguent...@suse.de> PR tree-optimization/105173 * tree-ssa-reassoc.cc (find_insert_point): Get extra insert_before output argument and compute it. (insert_stmt_before_use): Adjust. (rewrite_expr_tree): Likewise. * gcc.dg/pr105173.c: New testcase.
