5## Test that non-alloc section .foo can be assigned to a segment. Check that
6## the values of the offset and file size of this segment's PHDR are correct.

8## This functionality allows non-alloc metadata, which is not required at
9## run-time, to be added to a custom segment in a file. This metadata may be
10## read/edited by tools/loader using the values of the offset and file size from
11## the custom segment's PHDR. This is particularly important if section headers
12## have been stripped.
