+/* 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
+       };
+
+   If RELOC_MACROS_GEN_FUNC *is* defined, then instead the
+   following function will be generated:
+
+       static const char * foo PARAMS ((unsigned long rtype));
+       static const char *
+       foo (rtype)
+           unsigned long rtype;
+       {
+          switch (rtype)
+          {
+          case 0: return "R_foo_NONE";
+          case 1: return "R_foo_32";
+          default: return NULL;
