The patch doesn't create "V64SCImode", it creates "CV64SImode".
GET_UNIT_SIZE returns the size of V64SImode, so it is a tuple with a
vector in each field.
For GCN specifically, I think this would make sense (hypothetically); it
would give each notional SIMT "thread" a real and complex part in
consecutive registers, meaning it can add all the reals in one
instruction, and subtract all the imaginaries in another instruction,
and then multiply them together (or whatever) in a very natural way.
Meanwhile, the interleaved approach requires masking half the lanes to
do the add, mask the other lanes to do the subtract, do a permutation to
operate on them together, and then do it all again for the other half of
the values in the other vector. GCN also has load/store instructions
that can interleave two, three, or four, registers when storing them
(this is what V64DImode and V64TImode do already), so there's no extra
pain there.
Anyway, I didn't actually want to do any of that, at this time, I just
want DIVMOD to work but the middle-end models it as having a complex int
return value. If the complex modes do not exist then the middle-end does
not fail, but the code expands to nonsense RTL because the types are all
VOIDmode.

In my libgcc __divmodv64si4 routine I return a V64DImode value with the
two values as the high and low parts. GCN supports DImode values as
pairs of SImode registers, and V64DImode is a pair of V64SImode
registers such that each vector lane works exactly like the scalar case
(indeed, scalars are basically "V1DImode" for many operators, since the
scalar registers do not have a full set of instructions). This means
that the quotients are returned in v8 and the remainders are returned in
v9, and because all the compiler sees the wider mode it doesn't treat
them as an aggregate.
Then in my TARGET_EXPAND_DIVMOD_LIBFUNC implementation I have this
(simplified slightly to illustrate only the SImode case):
emit_library_call_value (libfunc, gen_rtx_REG (widemode,
RETURN_VALUE_REG),
LCT_NORMAL, widemode, op0, mode, op1, mode);
*quot = gen_rtx_REG (mode, RETURN_VALUE_REG);
*rem = gen_rtx_REG (mode, RETURN_VALUE_REG + 1);
I think this hook is necessary because this libfunc can have a custom
ABI? Maybe this isn't how a CV64SImode would actually get returned?
Anyway, this is how this libfunc works.
When CV64SImode exists the above works, otherwise I get an ICE because
it tries to store a VOIDmode register using my scatter_store_v64si
instruction and that isn't valid.

I have attempted to get expand_DIVMOD to do the right thing without the
new complex-of-vectors but there's no way to fix it with the existing
hooks. I have experimented with simply fixing up the VOIDmode values in
the backend, but the dataflow remains broken (the register it tries to
store is not connected to the "quot" and "rem" values provided by my
hook). I'll need to change the way DIVMOD works, somehow, but it's
relying on the complex int representation to pass the return values
onward so if I can't provide that then I'll need to code some kind of
non-obvious alternative.
Any suggestions? My unfinished patches are attached (I think I only need
to tidy a few bits and write a changelog).
Thanks

amdgcn: minimal V64TImode vector support
Just enough support for TImode vectors to exist, load, store, move,
without any real instructions available.
This is primarily for the use of divmodv64di4, which uses TImode to
return a pair of DImode values.
gcc/ChangeLog:
* config/gcn/gcn-protos.h (vgpr_4reg_mode_p): New function.
* config/gcn/gcn-valu.md (V_4REG, V_4REG_ALT): New iterators.
(V_MOV, V_MOV_ALT): Likewise.
(scalar_mode, SCALAR_MODE): Add TImode.
(vnsi, VnSI, vndi, VnDI): Likewise.
(vec_merge, vec_merge_with_clobber, vec_merge_with_vcc): Use V_MOV.
(mov<mode>, mov<mode>_unspec): Use V_MOV.
(*mov<mode>_4reg): New insn.
(mov<mode>_exec): New 4reg variant.
(mov<mode>_sgprbase): Likewise.
(reload_in<mode>, reload_out<mode>): Use V_MOV.
(vec_set<mode>): Likewise.
(vec_duplicate<mode><exec>): New 4reg variant.
(vec_extract<mode><scalar_mode>): Likewise.
(vec_extract<V_ALL:mode><V_ALL_ALT:mode>): Rename to ...
(vec_extract<V_MOV:mode><V_MOV_ALT:mode>): ... this, and use V_MOV.
(vec_extract<V_4REG:mode><V_4REG_ALT:mode>_nop): New 4reg variant.
(fold_extract_last_<mode>): Use V_MOV.
(vec_init<V_ALL:mode><V_ALL_ALT:mode>): Rename to ...
(vec_init<V_MOV:mode><V_MOV_ALT:mode>): ... this, and use V_MOV.
(gather_load<mode><vnsi>, gather<mode>_expr<exec>,
gather<mode>_insn_1offset<exec>, gather<mode>_insn_1offset_ds<exec>,
gather<mode>_insn_2offsets<exec>): Use V_MOV.
(scatter_store<mode><vnsi>, scatter<mode>_expr<exec_scatter>,
scatter<mode>_insn_1offset<exec_scatter>,
scatter<mode>_insn_1offset_ds<exec_scatter>,
scatter<mode>_insn_2offsets<exec_scatter>): Likewise.
(maskload<mode>di, maskstore<mode>di, mask_gather_load<mode><vnsi>,
mask_scatter_store<mode><vnsi>): Likewise.
* config/gcn/gcn.cc (gcn_class_max_nregs): Use vgpr_4reg_mode_p.
(gcn_hard_regno_mode_ok): Likewise.
(GEN_VNM): Add TImode support.
(USE_TI): New macro. Separate TImode operations from non-TImode ones.
(gcn_vector_mode_supported_p): Add V64TImode, V32TImode, V16TImode,
V8TImode, and V2TImode.
(print_operand): Add 'J' and 'K' print codes.
