| // Function MultiVersioning (FMV) properties. FMV features are accepted by the |
| // attributes target_version and target_clones, and they correspond to a mapping |
| // from the FMV feature name to: |
| // - A bit in the FMV ABI, as defined by the ACLE. |
| // - The FMV priority, as defined by the ACLE. |
| // - A list of backend features. |
| // |
| // The list of backend features is not a set of dependencies; it is specific to |
| // LLVM and indicates how to do codegen when the FMV feature is present. |
| // |
| // Therefore FMVExtensions are separated from regular AArch64 Extensions, which |
| // encode dependencies between themselves and other SubtargetFeatures. |
