+   Tests correct signedness of operations on bitfields; in particular

+   casts are present.
+
+   The C front end was eliding the cast of an unsigned bitfield to
+   unsigned as a no-op, when in fact it forces a conversion to a
+   full-width unsigned int. (At the time of writing, the C++ front end
+   has a different bug; it erroneously promotes the uncast unsigned
+   bitfield to an unsigned int).

+   Source: Neil Booth, 25 Jan 2002, based on PR 3325 (and 3326, which
+   is a different manifestation of the same bug).

+       {
+	 int inc = incs[i];

+	 tmp_results[i] = result;
+       }
+     memcpy (results, tmp_results, sizeof (results));
+
+   but without the outermost loop.  The idea is to create high register
+   pressure and ensure that some INC and PTR variables are spilled.
+
+   On ARM targets, sequences like "result += *ptr, ptr += inc" can
+   usually be implemented using (mem (post_modify ...)), and we do
+   indeed create such MEMs before reload for this testcase.  However,
+   (post_modify ...) is not a valid address for coprocessor loads, so
+   for -mfloat-abi=softfp, reload reloads the POST_MODIFY into a base
+   register.  GCC did not deal correctly with cases where the base and
+   index of the POST_MODIFY are themselves reloaded.  */
