This is used by the compiler code to manage some resources when calling the gdb-generated inferior function. 2014-05-16 Jan Kratochvil * 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.
