+/* 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. */
