> Hi all,
>=20
> This patch adds support for the vectorisation of the rounding
> functions:
> floorf, ceilf, truncf, roundf. These can be implemented using the ARMv8
> NEON
> instructions: vrintm, vrintp, vrintz, vrinta.
> This is done by defining the TARGET_VECTORIZE_BUILTINS and
> TARGET_VECTORIZE_BUILTIN_VECTORIZED_FUNCTION macros and the function
> arm_builtin_vectorized_function that returns the decl of the vector
> form
> of a builtin function, or NULL_TREE if no vector variant exists.
>=20
> No regressions on arm-none-eabi with AEM.
>=20
> Ok for trunk?
