There are still failures with the ODR support when building the testcases with -gdwarf-5, specifically: FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-class-ns.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-def-decl.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-loc.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-struct.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-struct-ns.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-union.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-class.sh FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-union-ns.sh It looks like ODR detection simply doesn't work with DWARF5, so no size reduction is produced. I haven't figured out why yet. That said, it would be nice to see a new release. We can always say that ODR support is experimental and doesn't yet work for DWARF5. Cheers, Mark
