 All unallocated relocation types are reserved for use by future revisions of this specification.
 
+PAuthABI relocations
+^^^^^^^^^^^^^^^^^^^^
+
+The `PAuthABIELF64`_ ELF extension, currently in Alpha state, defines several relocations in the vendor experiment space. Arm reserves codes 580 to 600 for static `PAuthABIELF64`_ relocations and 1040 - 1060 for dynamic `PAuthABIELF64`_ relocations. When the extension moves to Release state the relocations defined in `PAuthABIELF64`_ will be added to this document and all unused codes in the reserved ranges will be released.
