s-intman-posix.adb (Notify_Exception): Adjust signature, as handler for sigactions with SA_SIGINFO set.
2005-03-08 Olivier Hainque <hainque@adacore.com>
* s-intman-posix.adb (Notify_Exception): Adjust signature, as handler
for sigactions with SA_SIGINFO set. Call
__gnat_adjust_context_for_raise before raising, to perform the
potentially required adjustments to the machine context for the GCC
unwinder.
* raise.h (__gnat_adjust_context_for_raise): New prototype.
* init.c (__gnat_adjust_context_for_raise) HPUX: Initial revision.
Adjust PC by one in the provided machine context.
(__gnat_install_handler) HPUX: Set SA_SIGINFO in the sigaction flags,
so that the handler is passed the context structure to adjust prior to
the raise.
(__gnat_error_handler) HPUX: Adjust the signature to match what an
SA_SIGINFO sigaction should look like. Call
__gnat_adjust_context_for_raise before actually raising.
(__gnat_adjust_context_for_raise): Default noop to help PC
adjustments before raise from signal handlers.
(__gnat_error_handler): Indirectly call a predicate function to
determine if a condition should be resignaled or not.
(__gnat_set_resignal_predicate): User interface to modify the predicate.
(__gnat_default_resignal_p): Default GNAT predicate.
