--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

(zero_extend:DI (subreg:SI (symbol_ref:DI ("y") [flags 0x2] <var_decl
0x7ffff79d01c8 y>) 0))


DEF_RTL_EXPR(SUBREG, "subreg", "ep", RTX_EXTRA)

So subreg is not handled.

"p" is a poly_uint16 offset.

It was "i" before r8-5466-g91914e56a5e952.

It looks like it was a latent bug until now too.
