Expand description
This macro tests, at runtime, whether an aarch64
feature is enabled on aarch64 platforms.
Currently most features are only supported on linux-based platforms.
This macro takes one argument which is a string literal of the feature being tested for. The feature names are mostly taken from their FEAT_* definitions in the ARM Architecture Reference Manual.
