6 * lex.c (search_line_fast): Add new version to be used for Power8
7 and later targets when Altivec is enabled. Restrict the existing
8 Altivec version to big-endian systems so that lvsr is not used on
9 little endian, where it is deprecated. Remove LE-specific code
10 from the now-BE-only version.
