-Subject: [PATCH] tree-optimization/109469 - SLP with returns-twice region
- start
-
-The following avoids an SLP region starting with a returns-twice
-call where we cannot insert stmts at the head.
-
-	PR tree-optimization/109469
-	* tree-vect-slp.cc (vect_slp_function): Skip region starts with
-	a returns-twice call.
-
-	* gcc.dg/torture/pr109469.c: New testcase.
