I can limit these tests to Linux. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83839 Bootstrap failed on Dawning due to lack of ".set" directive in assembler. I uploaded a patch: https://gcc.gnu.org/bugzilla/attachment.cgi?id=43124 There is no confirmation on it. Also there may be test failures on Dardwin due to difference in assembly output. -- H.J.
