Instead first perform use-based DCE and then remove stmts which may have uses in code that CFG cleanup will remove. This requires tracking stmts in to_remove by their SSA def so we can check whether it was removed before without running into the issue that PHIs can be ggc_free()d upon removal. So this adds to_remove_defs in addition to to_remove which has to stay to track GIMPLE_NOPs we want to elide. PR tree-optimization/116460 * tree-ssa-forwprop.cc (pass_forwprop::execute): First do simple_dce_from_worklist and then remove stmts in to_remove. Track defs to be removed in to_remove_defs. * g++.dg/torture/pr116460.C: New testcase.
