introduce call_function_by_hand_dummy
This provides a variant of call_function_by_hand that allows the dummy
frame destructor to be set. This is used by the compiler code to
manage some resources when calling the gdb-generated inferior
function.
gdb/ChangeLog
2014-12-12 Jan Kratochvil <jan.kratochvil@redhat.com>
* infcall.h (call_function_by_hand_dummy): Declare.
* infcall.c (call_function_by_hand): Use
call_function_by_hand_dummy.
(call_function_by_hand_dummy): Rename from call_function_by_hand.
Add arguments. Register a destructor.
