+Subject: [PATCH] [ARM] PR target/71056: Don't use vectorized builtins when
+ NEON is not available
+
+ PR target/71056
+ * config/arm/arm-builtins.c (arm_builtin_vectorized_function): Return
+ NULL_TREE early if NEON is not available. Remove now redundant check
+ in ARM_CHECK_BUILTIN_MODE.
+
+ * gcc.target/arm/pr71056.c: New test.
