It seems to me, the last phenomena is explained by swift compiler bug. Let us
look into clang/lib/Lex/ModuleMap.cpp source file, method parseHeaderDecl. We
can find, for example, following lines:
if (llvm::sys::path::is_absolute(Header.FileName)) {
RelativePathName = Header.FileName;
File = SourceMgr.getFileManager().getFile(RelativePathName);
}
We can see, that sysroot (or isysroot) argument is ignored. What can you say
about that?
