            Bug ID: 78382
           Summary: ICE when compiling on aarch64 in ILP32 mode with
                    traditional thread local storage and pic
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sje at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64

Compiling this code:

__thread int abc;
void foo()
{
        int *p;
        p = &abc;
}

With thee options '-O0 -fpic -mabi=ilp32 -mtls-dialect=trad' generates an ICE
in the aarch64 backend.

You may need to configure GCC with "--with-multilib-list=lp64,ilp32" to get
a GCC that supports the "-mabi=ilp32" flag.
