title: Create new segment in linker script while keeping default ones
body: <p>I have created some special sections in a linked file and I want them to be in separated segments to have different page permissions.</p>
  
  <p>In linker script, PHDRS command can specify segments in linked file. However, as the <a href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/4/html/Using_ld_the_GNU_Linker/phdrs.html" rel="noreferrer">document</a> says, PHDRS will create no default-defined segments other than specified in the command. And I found no PHDRS command in <code>ld --verbose</code> output.</p>
  
  <p>Is there any way to keep the default ones? Or what is the default specifications of segments so I can write them in my own linker script?</p>
