            Bug ID: 67848
           Summary: ICE on gcc.dg/atomic/pr65345-4.c and
                    gcc.dg/pr65345-3.c
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: clyon at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64-none-elf, aarch64-none-linux-gnu,
                    arm-none-linux-gnueabihf

The tests introduced at r228343 cause ICEs on aarch64-none-elf,
aarch64-none-linux-gnu and arm-none-linux-gnueabihf targets (works for me on
arm-none-linux-gnueabi).

On aarch64-none-elf:

On aarch64-none-linux-gnu and arm-none-linux-gnueabihf we also have
gcc.dg/atomic/pr65345-4.c with a similar backtrace:
