@cindex @code{prefer-vector-width} function attribute, x86
On x86 targets, the @code{prefer-vector-width} attribute informs the
compiler to use @var{OPT}-bit vector width in instructions
instead of the default on the selected platform.
Valid @var{OPT} values are:
@table @samp

No extra limitations applied to GCC other than defined by the selected platform.

Prefer 128-bit vector width for instructions.

Prefer 512-bit vector width for instructions.

On the x86, the inliner does not inline a
function that has different target options than the caller, unless the
callee has a subset of the target options of the caller. For example
a function declared with @code{target("sse3")} can inline a function
with @code{target("sse2")}, since @code{-msse3} implies @code{-msse2}.
