That statement seems to contradict what Peter Smith says: https://github.com/ClangBuiltLinux/linux/issues/1288#issuecomment-770693582 https://reviews.llvm.org/D58655#1410282 > I can send a patch to address the build error and mark big-endian > as "depends on !LD_IS_LLD || COMPILE_TEST" to reflect that > and help with randconfig testing. I have no strong opinion on handling this though. Cheers, Nathan
