Guido, Here is a mockup patch that should be roughly what you need. Note that I haven't sanity checked the exact types and sizes for the calls in libgcc-compat. Someone on mips will have to do that. Also if you haven't gone through every single debian package and scanned for symbols you may need to add more to libgcc-compat.c. You can look at...
http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/powerpc/Attic/libgcc-compat.c?cvsroot=glibc to see some other ones you may actually need. ------------------------------------------------------------------------------- diff -uNr libc/sysdeps/mips/Dist libc.mips/sysdeps/mips/Dist --- libc/sysdeps/mips/Dist 2001-07-27 22:52:19.000000000 -0700 +++ libc.mips/sysdeps/mips/Dist 2002-10-14 06:28:16.000000000 -0700 @@ -1,3 +1,5 @@ +divdi3.c +libgcc-compat.c setjmp_aux.c regdef.h sgidefs.h diff -uNr libc/sysdeps/mips/divdi3.c libc.mips/sysdeps/mips/divdi3.c --- libc/sysdeps/mips/divdi3.c 1969-12-31 17:00:00.000000000 -0700 +++ libc.mips/sysdeps/mips/divdi3.c 2002-10-14 06:03:04.000000000 -0700 @@ -0,0 +1,44 @@ +/* 64-bit multiplication and division libgcc routines for 32-bit Mips + Copyright (C) 2002 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
