+/* These macros are used by the various *.h target specific header
+   files to either generate an enum containing all the known relocations
+   for that target, or if RELOC_MACROS_GEN_FUNC is defined, a recognition
+   function is generated instead.  (This is used by binutils/readelf.c)
+
+   Given a header file like this:
+
+   	START_RELOC_NUMBERS (foo)
+   	    RELOC_NUMBER (R_foo_NONE,    0)
+   	    RELOC_NUMBER (R_foo_32,      1)
+   	    EMPTY_RELOC  (R_foo_good)
+   	    FAKE_RELOC   (R_foo_illegal, 9)
+   	END_RELOC_NUMBERS (R_foo_count)
+
+   Then the following will be produced by default (ie if
+   RELOC_MACROS_GEN_FUNC is *not* defined).
+
+   	enum foo
+	{
+   	  R_foo_NONE = 0,
+   	  R_foo_32 = 1,
+	  R_foo_good,
+   	  R_foo_illegal = 9,
+   	  R_foo_count
+   	};
+
+   Note: The value of the symbol defined in the END_RELOC_NUMBERS
+   macro (R_foo_count in the case of the example above) will be
+   set to the value of the whichever *_RELOC macro precedes it plus
+   one.  Therefore if you intend to use the symbol as a sentinel for
+   the highest valid macro value you should make sure that the
+   preceding *_RELOC macro is the highest valid number.  ie a
+   declaration like this:
+
+   	START_RELOC_NUMBERS (foo)
+   	    RELOC_NUMBER (R_foo_NONE,    0)
+   	    RELOC_NUMBER (R_foo_32,      1)
+   	    FAKE_RELOC   (R_foo_illegal, 9)
+   	    FAKE_RELOC   (R_foo_synonym, 0)
+   	END_RELOC_NUMBERS (R_foo_count)
+
+   will result in R_foo_count having a value of 1 (R_foo_synonym + 1)
+   rather than 10 or 2 as might be expected.
+
+   Alternatively you can assign a value to END_RELOC_NUMBERS symbol
+   explicitly, like this:
+
+   	START_RELOC_NUMBERS (foo)
+   	    RELOC_NUMBER (R_foo_NONE,    0)
+   	    RELOC_NUMBER (R_foo_32,      1)
+   	    FAKE_RELOC   (R_foo_illegal, 9)
+   	    FAKE_RELOC   (R_foo_synonym, 0)
+   	END_RELOC_NUMBERS (R_foo_count = 2)
+
+   If RELOC_MACROS_GEN_FUNC *is* defined, then instead the
+   following function will be generated:
+
+   	static const char *foo (unsigned long rtype);
+   	static const char *
+   	foo (unsigned long rtype)
+   	{
+   	   switch (rtype)
+   	   {
+   	   case 0: return "R_foo_NONE";
+   	   case 1: return "R_foo_32";
+   	   default: return NULL;
+   	   }
+   	}
