--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> --- If I recall correctly, old binutils issue warning when plugin produce IL file which is done for incremental linking. I do not think there is a way to prevent this message from gcc side other than requiring binutils 2.27+ One way to silence the warning would be simply to add -flinker-output=nolto-rel to all the testcases (so we do not do incremental IL linking) but it will make it still harder to add testcases for incremental link IL linking if we want to support them on older binutils somehow (i.e. by disabling the tests or tolerating false warning)
