Subject: a.out questions
Date: Fri, 01 May 1998 13:02:00 -0000 [thread overview]
Message-ID: <Pine.LNX.3.96.980501220036.256A-100000@bartlet.df.lth.se> (raw)
I'm in the process of porting binutils to NetBSD's a.out shared library
format, and I have a couple of questions...
In our exec header, there is a flag that tells if the code in the file
is position independent. Should I add this to the flags in BFD, or is
this attribute obscure enough to keep only as private data in the a.out
backend?
Since I thought that our a.out format was close to sunos, I have based
my version on sunos.c. There are however two differences that are big
enough to cause problems;
- The nlist pointed to by the dynamic_link structure isn't a nlist in
NetBSD (it's a nlist with on word appended.) This does unfortunatly
break (at least) aout_link_add_symbols() in aoutx.h
- Weak symbols are handled by setting a flag in the n_other field (instead
of handling it in n_type that binutils does). This breaks the conversion
functions in aoutx.h.
Are there any hooks I have missed that can solve my problems? As far I can
see, the hooks are present on a too high level, so I end up duplicating
nearly the whole aoutx.h. Or should I try to add new hooks?
By the way, are this mailing list the correct place to discuss changes to
ld, or are there a ld list somewhere?
