            Bug ID: 18748
           Summary: Inconsistent handling of  __TEXT,__cstring and
                    __TEXT,__ustring with regards to L labels
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: MC

Given

------------------------------
.section  __TEXT,__cstring
L1:

.section  __TEXT,__ustring
L2:
------------------------------

We put L1 in symbol table but not L2. Whatever relocation issues that exist
that require L1 to be visible also exist for L2, no?

If the relocation issue still exists, it looks like we would be miscompiling
utf-16 string.

The bigger question is why put L symbols in the symbol table? If the are
needed, why not just have codegen use "l"?
