Yes, that fixes the issue, thanks.
The only diff in the assembly now, compared to before the "else" patch, is the
zero-initialization is gone. This is good; the mysterious extra code seemed
like a step back

I think it also shows that the openMP SIMD handling for the SIMD vars lacks
optimization:
int D.2004[64];
int D.2003[64];
int D.2001[64];
...
those were supposed to be vector registers in the end,

This is the code:
vect__23.27_8 = .MASK_GATHER_LOAD (&MEM [(void *)&k + -88B], {
0, -15, -30, -45, -60, -75, -90, -105, -120, -135, -150, -165, -180, -195,
-210, -225, -240, -255, -270, -285, -300, -315, -3

The mask is a 64-bit integer value in the "exec" register.
I agree that I cannot see the problem staring at it. Like I said, I changed the
backend so that it generated the zero-initializers anyway, and the

We're not emitting the VEC_COND because type_mode_padding_p is false.
My check compares the precision of the scalar type vs the precision of the
vector mode's inner mode which is both 32 here: int vs E_V64SImod
