ATTRIBUTE_UNUSED

[Doug Evans]

Instead of doing things like this:

Index: m32r-dis.c
===================================================================
RCS file: /cvs/src/src/opcodes/m32r-dis.c,v
retrieving revision 1.4
diff -c -p -r1.4 m32r-dis.c

  static void
  print_normal (cd, dis_info, value, attrs, pc, length)
+ #ifdef CGEN_PRINT_NORMAL
       CGEN_CPU_DESC cd;
+ #else
+      CGEN_CPU_DESC cd ATTRIBUTE_UNUSED;
+ #endif

How about just

-      CGEN_CPU_DESC cd;
+      CGEN_CPU_DESC cd ATTRIBUTE_UNUSED;
