Hi,
When using -ggnu-pubnames to generate .debug_gnu_{names,types} sections we run
into:
...
$ gcc hello.c -g -ggnu-pubnames
$ dwz a.out
dwz: a.out: Unknown debugging section .debug_gnu_pubnames
...
Fix this conservatively by dropping the section, similar to how the
.debug_{names,types} sections are handled.
Committed to trunk.
Thanks,
- Tom
