This insn is created in the loop pass:

We had previously in gcse:

Here's the story on this problem. Ada bootstrap was broken on this
target by this change:
2005-04-08 Diego Novillo <dnovillo@redhat.com>
Merge from tree-cleanup-branch: VRP, store CCP, store
copy-prop, incremental SSA updating of FUD chains and
newly exposed symbols.
* Makefile.in (tree-ssa-copy.o): Depend on tree-ssa-propagate.h.
...
The resulting PR was fixed by Kazu with this change:
2005-04-15 Kazu Hirata <kazu@cs.umass.edu>
PR tree-optimization/20936.
* tree-ssa-ccp.c (visit_assignment): Fix a typo.
However, this didn't fix all the problems introduced by the original
change. With Kazu's patch, gnat1 went into an infinite loop in stage3
compiling ada.ads:
stage2/xgcc -Bstage2/ -B/home/dave/opt/gnu/gcc/gcc-4.1.0/hppa-linux/bin/ -c -g -
O2 -gnatpg -gnata -I- -I. -Iada -I../../gcc/gcc/ada ../../gcc/gcc/ada/ada.a
ds -o ada/ada.o
make[2]: *** [ada/ada.o] Interrupt
The above problem was fixed by this change:
2005-04-22 Jeff Law <law@redhat.com>
* tree-ssa-dom.c (block_defs_stack): Remove, no longer needed.
(restore_currdefs_to_original_value): Likewise.
(register_definitions_for_stmt): Likewise.
(tree_ssa_dominator_optimize): No longer initialize CURRENT_DEF
for each variable. Do not allocate/free block_defs_stack either.
Do not iterate if we just thread jumps. Only iterate if the
tree_cleanup_cfg does useful work (temporary).
(dom_opt_initialize_block): No longer push a marker on
BLOCK_DEFS_STACK.
(dom_opt_finalize_block): Removal call to restore currdefs.
Relax restrictions for recording edge equivalences.
(record_equivalences_from_phis): No longer need to track
CURRENT_DEF.
(optimize_stmt): Similarly.
(thread_across_edge): Simplify by removing the requirement that
statements in the block we are threading through must be nops.
(initialize_hash_element): Handle GOTO_EXPR.
Jeff's change exposed the current problem.
