<pre>I was playing around with llvm-size to see how good a fit it is with GNU size,
and discovered that its sysv output format does not match GNU's because it uses
different rules to GNU size's rules.
llvm-size's current rules are simply to omit any SHT_NULL, SHT_SYMTAB,
SHT_STRTAB, SHT_REL, and SHT_RELA sections. However, I observed that GNU size
sometimes includes at least relocation and string table sections. For example,
the .dynstr, .rela.plt and .rela.dyn sections are all included. I tried
generating an artificial input using yaml2obj to exercise this and have not
been able to identify the rules used, so I'm filing this bug for now rather
than providing a patch.
Likely whoever implements this will need to inspect the GNU size source code to
determine its rules.</pre>
