 Hi,
 
 I can confirm that this bug is still present on 3.3 branch and mainline  
 (20030506). It does not appear to be itanium2 related, and crashes just  
 fine from a generic cross compiler :-(

 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.

 Your attachment is empty.  If you send it again I can see if the problem
 still exists with the GCC 3.2 branch (soon to be released as 3.2.1) and
 the mainline.

Source file is from opendx 4.2 (www.opendx.org).
Compiling on a dual processor HP zx6000 Itanium-2
(1GHz).  Problem first encountered in gcc-2.96,
then in gcc-3.0.4.  Compiling with lower optimization
does not help.  Report from test of build
of gcc-3.2 has been submitted.
