>Description:
	When trying to build a cross-compiler (from Debian GNU/Linux 3.0,
	to HP-UX 11.22, I get the following internal error when the compiler
	tries to build itself:
	../../gcc-3.2/gcc/config/ia64/unwind-ia64.c: In function `alloc_reg_state':
	../../gcc-3.2/gcc/config/ia64/unwind-ia64.c:263: Internal compiler error in emit_move_insn, at expr.c:2776
	
>How-To-Repeat:
	Build binutils using the target and prefix values from the script listed
	in "configure with".  Then, build gcc using the script in the "configure
	with" field.  The ICE occurs when trying to compile the file gcc/
	config/ia64/unwind-ia64.c.  At least, that's what I did.  It appears
	that binutils is not involved in this particular problem, though it
	is needed to get this far in the build.
>Fix:
	No known workaround.  I tried several attempts to rewrite the code
	that causes the internal compiler error (in ia64intrin.c and in
	unwind-ia64.c) but made no progress.
