But if they are then the diff comes from this gas issue: https://sourceware.org/bugzilla/show_bug.cgi?id=3D26740 Even though unused gas -g might emit the input file name in the file table = in some situations. It is harmless but since the the generated assembly file n= ame might be different between stage2 and stage3 you will see a diff. If this really is an issue I think a workaround might be to make sure that = the .file 1 directive is emitted as early as possible.=
