From 48a0f6937d7c1faadf16f5ff7bd227a8392ddfe8 Mon Sep 17 00:00:00 2001 From: Andrew Pinski Date: Sun, 15 Sep 2024 16:43:24 -0700 Subject: vect: Set pattern_stmt_p on the newly created stmt_vec_info While adding simple_dce_worklist to the vectorizer, there was a regression due to the slp patterns would create a SSA name but never free it even if it never existed in the IR (this case as addsub but complex ones had the same issue). The reason why it was never freed was the stmt_vec_info was not marked as a pattern stmt, unlike the other pattern stmts that use vect_init_pattern_stmt instead of vec_info::add_pattern_stmt (which is used for SLP patterns). Bootstrapped and tested on x86_64-linux-gnu. gcc/ChangeLog: * tree-vectorizer.cc (vec_info::add_pattern_stmt): Set pattern_stmt_p.
