174 Changes to the Hexagon Target
175 -----------------------------
177 * Hexagon now supports auto-vectorization for HVX. It is disabled by default
178 and can be turned on with ``-fvectorize``. For auto-vectorization to take
179 effect, code genration for HVX needs to be enabled with ``-mhvx``.
180 The complete set of options should include ``-fvectorize``, ``-mhvx``,
181 and ``-mhvx-length={64b|128b}``.
183 * The support for Hexagon ISA V4 is deprecated and will be removed in the
184 next release.
