I'm not sure how to fix this. The debug trace here says it all: We try to
force something into an operand using an optab with a mode for which we have no
handler:

I have considered several possibilities; by far the simplest seems to be
to either just fail in this case in move_invariant_reg, or try calling
emit_move_insn on the original SET_SRC (set) if force_operand returns
NULL (http://gcc.gnu.org/ml/gcc-patches/2006-02/msg01009.html may be
useful in both cases).

Not fixed, please look for the same failure at PR32123.
start_sequence ();
op = force_operand (SET_SRC (set), reg);
+ if (!op)
+ {
+ end_sequence ();
+ goto fail;

if (op != reg)
Also, this fix is wrong, force opereand will not return NULL, but will ICE if
value can't be expanded via optab.

Hm, this bug was misteriously fixed. It was manifested as
gcc.target/i386/sse2-vec-6.c failure in [1] and this failure is not present
anymore in [2]:
[1]: http://gcc.gnu.org/ml/gcc-testresults/2007-05/msg01375.html
[2]: http://gcc.gnu.org/ml/gcc-testresults/2007-05/msg01530.html
I'm closing it as WORKSFORME due to these misteries. The fix is IMO still
wrong.

cofirmed by a couple of dupes. From PR 33428:

actually the fix in loop-invariant is correct for the original problem (where
expand_simple_binop fails and returns NULL_RTX).

(In reply to comment #23)
> This works for me on the branch. Uros, what is exactly failing?
The code that was removed from the mainline (Comment #21) is still present in
4.2 branch. According to comments #13, #15 and #17, this bug comes and goes,
and at this moment it looks that it is latent on the branch (at least all
testcases compile OK).
Let's pretend it is fixed as WORKSFORME.

Open bugs should not have milestones of past releases.
