/* MI's builder. */
PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.
