1079 The first three errors are only deteced by GAS while the
1080 AARCH64_OPDE_INVALID_VARIANT error can only be spotted by libopcodes as
1081 only libopcodes has the information about the valid variants of each
1084 The enumerators have an increasing severity. This is helpful when there are
1085 multiple instruction templates available for a given mnemonic name (e.g.
1086 FMOV); this mechanism will help choose the most suitable template from which
1087 the generated diagnostics can most closely describe the issues, if any. */
