GNU ld on x86 Solaris

[Fred Richardson]

Mike-

Thanks for the info!  I took a closer look at the program headers when
I link with the Solaris x86 linker.  Here are the 6 fields it uses:

     ============================================
    |  On a x86 Solaris box:

    % ../binutils/objdump --all-headers foo.2

    |  On a sparc Solaris box:

So I wonder what "NOTE" is for...

I also found that if I run the linker without including:
    /usr/ccs/lib/values-Xa.o
the program links successfully.  But on the sparc, the same file is
included without causing a hitch...

Well, one further clue.  On the sparc, each of these files:
    /usr/ccs/lib/values-Xa.o
    /usr/ccs/lib/values-Xc.o
    /usr/ccs/lib/values-Xs.o
    /usr/ccs/lib/values-Xt.o
has these sections:
     0 .text
     1 .data
     2 .rodata
     3 .stab.index
     4 .stab.indexstr
     5 .comment

but on the x86, they have these sections:
     0 .text
     1 .stab.index
     2 .stab.indexstr
     3 .comment
     4 .data
     5 .stab.excl
     6 .stab.exclstr

Could the ".stab.excl" and ".stab.exclstr" have something to do with
the new "NOTE" section?  I'm afraid I don't really know what any of
this is...
