From 8cf64490f293549a0b8e64342d7c97099df19974 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 3 Jun 2011 15:32:44 +0000 Subject: [PATCH] gdb * python/py-inferior.c (python_inferior_exit): Use inferior's exit code fields. * python/py-exitedevent.c (create_exited_event_object): Change type of 'exit_code'. Optionally add exit_code attribute. (emit_exited_event): Change type of 'exit_code'. * python/py-event.h (emit_exited_event): Update. * mi/mi-interp.c (mi_inferior_exit): Print exit code. * infrun.c (handle_inferior_event): Set exit code fields on inferior. * inferior.h (struct inferior) : New fields. * inferior.c (exit_inferior_1): Initialize new fields. gdb/doc * gdb.texinfo (GDB/MI Async Records): Document 'exit-code' field.
