Summary: NetBSD uses typical UNIX interfaces. All tests pass except instrprof-dlopen-dlclose-gcov.test, as there is not supported semantics of atexit(3) in dlopen(3)ed+dlclose(3)d DSO. NetBSD also ships an older version of LLVM profile (ABI v.2 predating ABI v.4 in upstream version) inside libc. That copy has been manually removed during the porting and testing process of the upstream version to NetBSD. Otherwise there were conflicts between them two.
