This patch

2003-03-31  Eric Christopher  <echristo at redhat dot com>

	* combine.c (can_combine_p): Allow ZERO_EXTRACT and     STRICT_LOW_PART.
	(combinable_i3pat): Remove call to expand_field_assignment and
	#if 0'd code.

introduces a number of testsuite regressions on hppa64-hp-hpux11*.  For
example, the following ICE occurs with gcc.c-torture/compile/920501-13.c:

-bash-2.05b$ /xxx/gnu/gcc-3.3/objdir/gcc/stage1/xgcc -B/xxx/gnu/gcc-3.3/objdir/gcc/stage1/ -S -O1  920501-13.c
920501-13.c: In function `y':
920501-13.c:1: internal compiler error: in find_free_reg, at local-alloc.c:2185
