--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Your testcase cannot be built. On GIMPLE ShowBug looks ok so the issue must
be at RTL expansion. _NOTE_ that *(volatile uint32_t*) makes alignment
guarantees to the access while your TimerRegisters struct is aligned at byte
boundary only! I suppose you may want
__attribute__((__packed__,aligned(alignof(uint32_t)))))?
