            Bug ID: 42309
           Summary: Asm goto expected a symbol reference
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux

When compiling the following code I get an error:

int main() {
    asm goto( "jmp %l[labelname]" : /* no outputs */ : /* inputs */ : /*
clobbers */ : labelname /* any labels used */ );
    int a;
    labelname:
    a = 0;
    a++;
    return a;
}


test.c:2:15: error: expected a symbol reference
    asm goto( "jmp %l[labelname]" : /* no outputs */ : /* inputs */ : /*
clobbers */ : labelname /* any labels used */ );
              ^
<inline asm>:1:8: note: instantiated into assembly here
        jmp ""
              ^
1 error generated.

but when compiled with -no-integrated-as I do not get an error.
