@option{-mabi=altivec} to adjust the current ABI with AltiVec ABI
enhancements.
When @option{-maltivec} is used, rather than @option{-maltivec=le} or
@option{-maltivec=be}, the element order for AltiVec intrinsics such
as @code{vec_splat}, @code{vec_extract}, and @code{vec_insert}
When @option{-maltivec} is used, the element order for AltiVec intrinsics
such as @code{vec_splat}, @code{vec_extract}, and @code{vec_insert}
match array element order corresponding to the endianness of the
target. That is, element zero identifies the leftmost element in a
vector register when targeting a big-endian platform, and identifies
the rightmost element in a vector register when targeting a
little-endian platform.
@item -maltivec=be
@opindex maltivec=be
Generate AltiVec instructions using big-endian element order,
regardless of whether the target is big- or little-endian. This is
the default when targeting a big-endian platform. Using this option
is currently deprecated. Support for this feature will be removed in
GCC 9.
The element order is used to interpret element numbers in AltiVec
intrinsics such as @code{vec_splat}, @code{vec_extract}, and
@code{vec_insert}. By default, these match array element order
corresponding to the endianness for the target.
@item -maltivec=le
@opindex maltivec=le
Generate AltiVec instructions using little-endian element order,
regardless of whether the target is big- or little-endian. This is
the default when targeting a little-endian platform. This option is
currently ignored when targeting a big-endian platform.
The element order is used to interpret element numbers in AltiVec
intrinsics such as @code{vec_splat}, @code{vec_extract}, and
@code{vec_insert}. By default, these match array element order
corresponding to the endianness for the target.
