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:

Tejas, I can only reproduce this with -fPIC using trunk r218582. No issue
without this option.

Yes, but I don't know how to change the "Assigned to" field after I logged in
as "fei.yang0953@gmail.com". Can anyone help me on this? Thanks.
