## Non-SHF_ALLOC sections are placed after all SHF_ALLOC sections. They will
## thus not be contained in a PT_LOAD segment. data2 has a PT_LOAD segment,
## even if it is preceded by a non-SHF_ALLOC section. Non-SHF_ALLOC orphan
## sections have zero addresses.
## NOTE: GNU ld assigns non-zero addresses to non-SHF_ALLOC non-orphan sections.
