            Bug ID: 59904
           Summary: [ARM] tls-reload-1.c fails
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: christophe.lyon at st dot com

Since commit 206897 (LRA fix PR rtl-optimization/59858)
I have noticed that:
gcc.dg/torture/tls/tls-reload-1.c  -Os  -pie -fPIE  execution test
gcc.dg/torture/tls/tls-reload-1.c  -Os  -pie -fpie  execution test

the compiler used to ICE, but after the LRA fix the generated code is not
functional.

I have tested with qemu-arm, target arm-none-linux-gnueabi, --with-mode=thumb
--with-cpu=cortex-a9, using RUNTESTFLAGS=-march=armv5t

gcc.log contains:
qemu: uncaught target signal 6 (Aborted) - core dumped
