Subject: [PATCH] Partial backport r256656
2018-06-15 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.
