--- Comment #10 from William Ferreira <wqferr at gmail dot com> ---
I come here looking for help; I am confused with regards to some features of
the Dwarf assembler.

In line 503 of gdb.dwarf2/dwarf.exp, it states:

If VALUE starts with the ":" character, then it is a label
    reference.  The rest of VALUE is taken to be the name of a label,
    and DW_FORM_ref4 is used.  See 'new_label' and 'define_label'.

But in line 55 of gdb.dwarf2/dynarr-ptr.exp, I find:

{DW_AT_type :$integer_label}

Where both the : prefix for a label value and the TCL variable expansion symbol
$ are used. From my understanding of the documentation pasted above, the
correct usage would have been:

{DW_AT_type :integer_label}

Since integer_label is a label declared previously in the file.

Could someone explain to me what I am missing, please?
