+Subject: [PATCH] Partial backport r256656
+
+2018-06-29  Martin Liska  <mliska@suse.cz>
+
+        Backport from mainline
+        2018-01-10  Kelvin Nilsen  <kelvin@gcc.gnu.org>
+
+        * lex.c (search_line_fast): Remove illegal coercion of an
+        unaligned pointer value to vector pointer type and replace with
+        use of __builtin_vec_vsx_ld () built-in function, which operates
+        on unaligned pointer values.
+
+Upstream-Status: Backport
+Signed-off-by: Joel Stanley <joel@jms.id.au>
