--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems tree-data-ref.c creates on this testcase (many apparently) ADDR_EXPRs of
these hard register VAR_DECLs and some of them survive until expansion, which
ICEs on them.  We should never try to create ADDR_EXPR of DECL_HARD_REGISTER
VAR_Ps IMHO.
