           Summary: internal compiler error: in gen_movsi when compiling
                    on arm some files of lttng-tools with -fPIE
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target

Preprocessed problematic file main.i

When I try to compile the attached file on arm, I get this error messaage:

main.c: In function ‘thread_manage_kernel’:
main.c:886:1: internal compiler error: in gen_movsi, at config/arm/arm.md:5539
 }

I compile with:
gcc -fPIE -O2 -c main.i
if I remove -fPIE, it compiles correctly. 

Using gcc 3.8.1 on fedora.
