           Summary: Clang ignores leading dot in symbol name
           Product: clang
           Version: unspecified
          Platform: PC
               URL: http://svn.freebsd.org/viewvc/base/head/lib/libc/gmon/gm
                    on.c?view=markup
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: LLVM Codegen
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: ed at 80386.nl

When compiling the attached code with GCC, nm will show the following:

                 U .foo
0000000000000000 T main

If we compile the same code with LLVM, we get:

                 U foo
0000000000000000 T main

This causes FreeBSD's libc to load correctly. If libc is compiled with LLVM,
except gmon.c, libc seems to work properly.
