Fix typo in DWARF 5 line table readers
|
|
|
|
This typo meant the directory entry was most often zero, which
|
|
happened to be sometimes correct anyway (since zero is the compdir).
|
|
So for simple testcases it looked correct. But it would be wrong for
|
|
compilation units not in the current compdir. Like files compiled with
|
|
a relative of absolute path.
|
|
|
|
The same typo was in both readdwarf.c (read_dwarf2_lineblock) and
|
|
readdwarf3.c (read_filename_table). read_dwarf2_lineblock also had
|
|
an extra "dwarf" string in the debug-line output.
