A full comparison build is now running. I should have results soon. In the
meantime, I tried it on a target that generates a 30Mb shared object:

Without your patch, I see these segment sizes:

     text      data       bss     debug debug.dwo    symtab    strtab
other     total filename
  8505260    444768    308624  12140854         0   1226952   5631742
1632669  29588116 file.so


With your patch:
     text      data       bss     debug debug.dwo    symtab    strtab
other     total filename
  8505260    444768    308624  12565490         0   1226952   5631742
1632669  30012748 file.so

That's a 3.5% growth in debug info size, for a total size increase of ~1%.

I'll send numbers over a full build as soon as I get them.


Diego.
