 The submitter sent me his preprocessed source file, from which I
 extracted this small test case:
 
   typedef struct { float u; float v; } P2;
 
   static void PointInTri (P2 pl, P2 pn, P2 v0, P2 v1, P2 v2)
   {
     P2 e0 = v2;
   }
 
 This causes the same ICE in simplify_gen_subreg when compiled on
 ia64-linux with gcc version 3.3 20021106 (experimental) and with
 3.2.1 20021105 (prerelease).  GCC 2.96RH ICEs in emit_move_insn.
