Port to Linux-m68k. A lot of this work was done by Roman Hodek,
<Roman.Hodek@informatik.uni-erlangen.de>.
README.Linux-m68k:
Mention that we have a port to the 68k.
configure.in:
Add a test for two different sorts of signal handlers
void handler(int signum, struct sigcontext_struct context)
and
void handler(int signum, int code, struct sigcontext_struct context)
Set HAVE_SIGCONTEXT_STRUCT_2ARG or HAVE_SIGCONTEXT_STRUCT_3ARG
appropriately.
Add support for shared libraries on the m68k as they should
work.
Make "working struct sigcontext" tests use MR_GET_FAULT_ADDR.
boehm_gc/config.h:
Add some definitions for the m68k.
boehm_gc/os_dep.c:
Get fault addresses using m68k specific code.
runtime/mercury_conf.h.in:
Add new configuration definitions HAVE_SIGCONTEXT_STRUCT_2ARG,
and HAVE_SIGCONTEXT_STRUCT_3ARG.
runtime/mercury_faultaddr.h:
Add MR_GET_FAULT_ADDR.
runtime/mercury_goto.h:
Add support for non-local gotos with Linux-68k.
runtime/mercury_memory_handlers.c:
Handle 2 or 3 argument signal handlers.
