system-vms-ia64.ads (Stack_Check_Limits): New target parameter.
(Always_Compatible_Rep): New flag to control trampolines globally.
(Dynamic_Trampolines_Used): New flag for implementing the
No_Implicit_Dynamic_Code restriction more correctly (not yet used,
and not yet set correctly for some targets).
* s-taprop-vxworks.adb: Use stack limit method of stack checking.
Simply indirectly call s-stchop when a task is created.
* ali.ads:
New flag added: Stack_Check_Switch_Set which is set when '-fstack-check'
appears as an argument (entries A) in an ALI file.
* fe.h (Stack_Check_Limits): Declare new target parameter.
(Check_Implicit_Dynamic_Code_Allowed): New procedure.
* init.c: Declare __gnat_set_stack_limit_hook for VxWorks kernel RTS.
This variable is declared in C to be sure not subject to elaboration
code.
(__gnat_map_signal, VxWorks): In kernel mode, map SIGILL to
Storage_Error.
* targparm.ads, targparm.adb (Stack_Check_Limits): New parameter.
(Always_Compatible_Rep, Dynamic_Trampolines_Used): New parameters.
* s-stchop.ads: Add comments.
* s-stchop-vxworks.adb: Package almost fully rewritten to use stack
limit method of stack checking.
* s-stchop-limit.ads: New file.
