Hi,
With this executable:
...
$ gcc -ggdb3 -gdwarf-5 hello.c
...
we run into:
...
$ cp a.out 1; cp 1 2; ./dwz-for-test -m 3 1 2
./dwz-for-test: 1: Unhandled .debug_macro version 5
./dwz-for-test: 2: Unhandled .debug_macro version 5
./dwz-for-test: No suitable DWARF found for multifile optimization
...
Fix this by allowing version 5 when reading .debug_macro.
Committed to trunk.
Thanks,
- Tom
