| ## Test that non-alloc section .foo can be assigned to a segment. Check that |
| ## the values of the offset and file size of this segment's PHDR are correct. |
| ## |
| ## This functionality allows non-alloc metadata, which is not required at |
| ## run-time, to be added to a custom segment in a file. This metadata may be |
| ## read/edited by tools/loader using the values of the offset and file size from |
| ## the custom segment's PHDR. This is particularly important if section headers |
| ## have been stripped. |
