            Bug ID: 64240
           Summary: [5.0 Regression][AArch64] SMS-3.c causes runtime
                    exception(segfault) with -fPIC.
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: belagod at gcc dot gnu.org

When sms-3 is compiled with -fPIC for aarch64, the test itself segfaults during
execution.

 ../../bin/install/bin/aarch64-unknown-linux-gnu-gcc 
-fno-diagnostics-show-caret -fdiagnostics-color=never -O2 -fmodulo-sched
-funroll-loops -fdump-rtl-sms --param sms-min-sc=1
-fmodulo-sched-allow-regmoves  -lm -mcmodel=small testsuite/gcc.dg/sms-3.c -o
/tmp/sms-3.exe -g -fPIC

When I reverse this patch out, it runs fine:
