It also moves flag handling to finish_options per Jakub's request. As the -fsanitize-recover option comes from clang originally, I think this needs coordination with them (whether clang will also rename the option), and certainly keep -fsanitize-recover as a non-documented compat option alias for -fubsan-recover. So, can you please talk to the clang folks about it? Jakub
