The configure checks for sigcontext (aka sigcontext_struct) have failed
for a long time without anyone noticing. The MR_GET_FAULT_ADDR macro
that is also needed for the sigcontext code paths was only ever defined
for __i386__ and __mc68000__.
According to the sigaction(2) man page, the struct sigcontext
argument was obsoleted by the introduction of the SA_SIGINFO flag
(which we also have code for, though also not working either).
configure.ac:
Delete checks related to struct sigcontext.
Delete check for asm/sigcontext.h
runtime/mercury_conf.h.in:
Delete macros that are no longer defined.
runtime/mercury_memory_handlers.c:
runtime/mercury_signal.c:
runtime/mercury_signal.h:
Delete code for using signal handlers that take a sigcontext argument.
Add XXX where native GC casts a context parameter to
struct sigcontext * when it should be a ucontext_t *.
Possibly never tested.
runtime/mercury_faultaddr.h:
Delete this file containing only the MR_GET_FAULT_ADDR macro which is
no longer used.
runtime/RESERVED_MACRO_NAMES:
ssdb/RESERVED_MACRO_NAMES:
trace/RESERVED_MACRO_NAMES:
Delete macros that are no longer defined.
tools/configure_mingw_cross:
Don't need to set variables mercury_cv_sigcontext_struct_2arg and
mercury_cv_sigcontext_struct_3arg any more.
