A new testsuite directive, dg-lto-additional-options, has been introduced to simplify the process of adding specific compiler flags to existing LTO test configurations. Previously, overriding options with dg-lto-options removed default configurations, making it cumbersome to add flags like -Wall. This new directive allows augmenting the default set of options, proving useful for testing features like LTO diagnostic pragmas.
