+/* 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)
+ FAKE_RELOC (R_foo_illegal, 2)
+ EMPTY_RELOC (R_foo_max)
+ END_RELOC_NUMBERS
+
+ 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_illegal = 2,
+ R_foo_max
+ };
+
+ If RELOC_MACROS_GEN_FUNC *is* defined, then instead the
+ following function will be generated:
+
+ static char * foo PARAMS ((unsigned long rtype));
+ static char *
+ foo (rtype)
+ unsigned long rtype;
+ {
+ switch (rtype)
+ {
+ case 0: return "R_foo_NONE";
+ case 1: return "R_foo_32";
+ default: return NULL;
+ }
