Is All_Calls_Remote permitted in non DSA code?

Is All_Calls_Remote permitted in non DSA code?

[Dr. Adrian Wrigley]

Hi!

(Continuing my monolog on issues linked to Annex E...)

I have found that GNAT 3.15p generates code that won't run properly when
calling subprograms in a unit marked "pragma All_Calls_Remote;"

gnatmake builds the program fine, and then a Program_Error is raised
at runtime at the point of call.  I hadn't anticipated this.

Adding an Annex E pragma shouln't stop normal compilation of the code,
should it?  Simply adding a  "pragma Remote_Call_Interface;" doesn't stop
normal operation.

Thank you for your suggestions.

"pragma All_Calls_Remote" forces all calls to subprograms in the
designated units to go through the PCS (Partition Communication
Subsystem). Therefore, you have to use "gnatdist" to build your
application (which is part of GLADE) instead of "gnatmake".
