| ## This checks that: |
| ## 1) Address of _etext is the first location after the last read-only loadable segment. |
| ## 2) Address of _edata points to the end of the last non SHT_NOBITS section. |
| ## That is how gold/bfd do. At the same time specs says: "If the address of _edata is |
| ## greater than the address of _etext, the address of _end is same as the address |
| ## of _edata." (https://docs.oracle.com/cd/E53394_01/html/E54766/u-etext-3c.html). |
| ## 3) Address of _end is different from _edata because of 2. |
| ## 4) Addresses of _edata == edata, _end == end and _etext == etext. |
