+ The Scalable Vector Extension (SVE) is now supported as an
+ optional extension to the Armv8.2-A architecture and newer.
+ This support includes automatic vectorization with SVE instructions,
+ but it does not yet include the SVE Arm C Language Extensions (ACLE).
+ It can be enabled by specifying the <code>+sve</code> architecture
+ extension (for example, <code>-march=armv8.2-a+sve</code>).
+ By default, the generated code works with all vector lengths,
+ but it can be made specific to <i>N</i>-bit vectors using
+ <code>-msve-vector-bits=<i>N</i></code>.
