Hi,
With this exec:
...
$ gcc -gdwarf-5 -fdebug-types-section hello.c
...
we run into:
...
$ dwz a.out
dwz: a.out: DWARF CU type DW_UT_type unhandled
dwz: a.out: Could not find DWARF abbreviation 8620
...
Remove the second message by bailing out of read_debug_info once the
unhandled dwarf-5 CU type is encountered.
Committed to trunk.
Thanks,
- Tom
