Jeff/Vlad, how hard would it be to try to split the insn into two insns instead
of a spill failure (for insns using a MEM whose address uses more than one hard
register) - one which forces the address into register (assuming it is
supported) and the store (or load) which would use a simpler address form?

I guess it would be possible for reload to split an insn in some circumstances,
particularly when there's complex addressing modes and multiple registers dying
within the insn.
As you know, I've been poking at range splitting and we might be able to model
this case too. Right now I split based on unallocated pseudos and expect to
split ranges based on pseudos getting the wrong kind of register in the future.
However, there's a couple areas were we still want to split ranges and we may
be able to come up with a generic way to express the other ranges we want to
split:

If it is done in reload (and imho this is the most right place to do), I think
it would be hard. It needs some person with a good knowledge of the reload.
It is also possible to do some splitting in other parts of compiler but it
would an approximate solution (it means not all such cases will be avoided
or/and it will hurt performance in general case).

I want to say this is really a dup of bug 44174.

Try with "-O2 -fno-gcse -fno-omit-frame-pointer -m32", it fails on 4.6+.

> Reconfirmed.
BTW: Moving the complex address to the temporary (as proposed in Comment #4)
would help "atomic_compare_and_swap<dwi>_doubleword" on 32bit x86 targets, too.
This pattern uses cmpxchg8b_pic_memory_operand predicate to limit the number of
address registers for 32bit x86 targets, in order to avoid spill failures.
Please see i386/sync.md.
