Be careful with the frame pointer. On X86, for example, it is used to process exceptions in C++ programs. I don't know how it behaves in this case on m68k. Also, yesterday I add a problem with gcc 2.95 on m68k, and a program dealing with 64 bits integer. long long values where stored in the stack frame, link/unlk instructions where used, even if I add -fomit-frame-pointer. The best thing you can do, is try to run gdb on a program compiled without the frame pointer. -- Patrice Mandin WWW: http://pmandin.atari.org/ Programmeur Linux, Atari Spécialité: Développement, jeux
