Hi All,
This has been split off from the FMV docs patch.
Builds cleanly.
Thanks,
Alfie

GCC implements extensions for C as described in the ARM C Language
Extensions (ACLE) specification, which can be found at

SIMD

-The built-in intrinsics for the Advanced SIMD extension are available when
-NEON is enabled.

-Currently, ARM and AArch64 back ends do not support ACLE 2.0 fully. Both
-back ends support CRC32 intrinsics and the ARM back end supports the
-Coprocessor intrinsics, all from @file{arm_acle.h}. The ARM back end's 16-bit
-floating-point Advanced SIMD intrinsics currently comply to ACLE v1.1.
-AArch64's back end does not have support for 16-bit floating point Advanced
SIMD
-intrinsics yet.

+Not all aspects of ACLE are supported. Support for each feature of the ACLE
+can be determined with the @code{__ARM_FEATURE_@var{X}} macros.
See @ref{ARM Options} and @ref{AArch64 Options} for more information on the
availability of extensions.
