+/* Implement elf_backend_eh_frame_address_size.  This differs from
+   the default in the way it handles EABI64.
+
+   EABI64 was originally specified as an LP64 ABI, and that is what
+   -mabi=eabi normally gives on a 64-bit target.  However, gcc has
+   historically accepted the combination of -mabi=eabi and -mlong32,
+   and this ILP32 variation has become semi-official over time.
+   Both forms use elf32 and have pointer-sized FDE addresses.
+
+   If an EABI object was generated by GCC 4.0 or above, it will have
+   an empty .gcc_compiled_longXX section, where XX is the size of longs
+   in bits.  Unfortunately, ILP32 objects generated by earlier compilers
+   have no special marking to distinguish them from LP64 objects.
+
+   We don't want users of the official LP64 ABI to be punished for the
+   existence of the ILP32 variant, but at the same time, we don't want
+   to mistakenly interpret pre-4.0 ILP32 objects as being LP64 objects.
+   We therefore take the following approach:
+
+      - If ABFD contains a .gcc_compiled_longXX section, use it to
+        determine the pointer size.
+
+      - Otherwise check the type of the first relocation.  Assume that
+        the LP64 ABI is being used if the relocation is of type R_MIPS_64.
+
+      - Otherwise punt.
+
+   The second check is enough to detect LP64 objects generated by pre-4.0
+   compilers because, in the kind of output generated by those compilers,
+   the first relocation will be associated with either a CIE personality
+   routine or an FDE start address.  Furthermore, the compilers never
+   used a special (non-pointer) encoding for this ABI.
+
+   Checking the relocation type should also be safe because there is no
+   reason to use R_MIPS_64 in an ILP32 object.  Pre-4.0 compilers never
+   did so.  */
