            Bug ID: 27226
           Summary: ld.bfd contains huge .rodata section
           Product: binutils
           Version: 2.35.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: mliska at suse dot cz
  Target Milestone: ---

Looking at the size of ld.bfd binary I see:

$ bloaty /usr/bin/ld.bfd
    FILE SIZE        VM SIZE    
 --------------  -------------- 
  89.5%  7.78Mi  89.5%  7.78Mi    .rodata
   7.0%   623Ki   7.0%   623Ki    .text
   1.2%   103Ki   1.2%   103Ki    .rela.dyn

Where the .rodata section is full of linker scripts:

$ strings /usr/bin/ld.bfd | grep 'this script' | wc -l
927

So there are almost 1000 linker scripts. Would it be possible to save the
scripts in a more compressed form?

$ du -hs ld.bfd
8.7M    ld.bfd
$ xz ld.bfd
$ du -hs ld.bfd.xz
316K    ld.bfd.xz

So one can easily compress the binary size 30x.
