+    <li>The inline assembly register constraint <code>"A"</code> has
+        been renamed <code>"c"</code>.  This constraint is used to
+        select a floating-point register that can be used as the

+    <li>New inline assembly register constraints <code>"A"</code> and

+        resolve to all general registers when compiling for AM33, and
+        resolve to address registers only or data registers only when
+        compiling for MN10300.
