The GCC testsuite has gained a new directive, dg-lto-do incr-link, to facilitate testing of LTO’s incremental linking capabilities. This complements the existing dg-lto-do ar-link option, providing broader coverage for LTO’s various linking strategies. Documentation for the LTO testsuite has been updated accordingly.
