Problems with m68k-coff-ld

[jw@raven.inka.de (Josef Wolf)]

Hi there!

I have successfully built (and used) an m68k-coff cross-compiler hosted
on a linux box. But there are still some problems with it. Maybe someone
out there could help me with my problems?

First, the versions of the toolchain:
-rw-r-----   1 jw      jw     4480026 Jul 15  1996 binutils-2.7.tar.gz
-rw-r-----   1 jw      jw     7132291 Aug 14  1996 gcc-2.7.2.1.tar.gz
-rw-r-----   1 jw      jw       19184 Jan  6  1996 crossgcc-gcc-2.7.2.patch
-rw-r-----   1 jw      jw     1454028 Jan  6  1996 newlib-1.7.0.tar.gz

And (not installed yet...)
-rw-r-----   1 jw      jw      128790 Jul 21  1996 gdb-4.16-bdm-patches.tgz
-rw-r-----   1 jw      jw      464522 Apr 24  1996 gdb-4.16-testsuite.tar.gz
-rw-r-----   1 jw      jw     5996836 Apr 24  1996 gdb-4.16.tar.gz

Now the Problems:

- Things like

  static char *foo=NULL;
  void bar (void)
  {
    if (foo) do_something (foo);
  }

  fail because foo won't get initialized properly to NULL. Seems to be a
  problem with the startup-code. Currently it clears the BSS segment and
  copies the initialzed data (DATA segment) from ROM into RAM. Do I need
  to do more?

- With -g the compiler generates .file statements, which the linker strips
  off. So I can't do source-level-debugging :-(). Output-format is -ieee.

- When using the standard-library (newlib) the linker always catches the
  68020-version of the library. This leads to problems with my 68332 :-()
  This problem appears when I use m68k-coff-ld directly as well as when
  I use it through m68k-coff-gcc. The --verbose output seems to be OK, so
  I assume the libraries are not properly built? Here's the output:
