Inferior function calls are powerful but might lead to undesired results such as crashes when calling nested functions (frequently used in particular in Ada). This implements a GDB setting to disable calling inferior functions. Note: the idea is that if/when the 'slash command' patch is pushed, that this setting can be changed e.g. by using the shortcut /c. This is version 2 of the patch. It handles all the received comments, mostly replace 'can-call' by 'may-call', and avoid using 'inferior function call' in factor of 'calling function in the program'. 2019-04-26 Philippe Waroquiers <philippe.waroquiers@skynet.be> gdb/ChangeLog * NEWS: Mention the new set|show may-call-functions. * infcall.c (may_call_functions_p): New variable. (show_may_call_functions_p): New function. (call_function_by_hand_dummy): Throws an error if not may-call-functions. (_initialize_infcall): Call add_setshow_boolean_cmd for may-call-functions. gdb/testsuite/ChangeLog * gdb.base/callexit.exp: Test may-call-functions off. gdb/doc/ChangeLog * gdb.texinfo (Calling): Document the new set|show may-call-functions.
