   8 ## Sections matched by patterns between two SORT are sorted separately by input order.
   9 ## Note, GNU ld has a strange behavior with more than one SORT* https://sourceware.org/pipermail/binutils/2020-November/114083.html
  10 ## In the absence of SORT, our multi-pattern behavior matches GNU ld.
