Just like memcheck supports suppression files to hide known/intentional memory leaks, it would be useful if massif supported suppression files to provide --alloc-fn arguments for common malloc() wrappers. For example, I run massif for GLib applications using the following: --alloc-fn=g_malloc --alloc-fn=g_object_new --alloc-fn=g_malloc0 --alloc-fn=g_malloc0_n --alloc-fn=g_malloc_n --alloc-fn=g_realloc --alloc-fn=g_realloc_n --alloc-fn=g_slice_alloc --alloc-fn=g_slice_alloc0 --alloc-fn=g_type_create_instance --alloc-fn=g_object_new_internal --alloc-fn=g_object_new_with_properties --alloc-fn=g_object_newv --alloc-fn=g_object_new_valist --alloc-fn=g_try_malloc --alloc-fn=g_try_malloc_n --alloc-fn=g_hash_table_realloc_key_or_value_array --alloc-fn=realloc_arrays --alloc-fn=g_hash_table_resize --alloc-fn=g_hash_table_maybe_resize --alloc-fn=g_hash_table_insert_node --alloc-fn=g_hash_table_insert_internal --alloc-fn=g_hash_table_setup_storage just so that various internal GLib wrappers around malloc() are ignored and the output focuses on the code which is calling them. It would be more convenient to be able to put these arguments in the shared suppression file which GLib already installs for memcheck, so that users of GLib don’t have to reinvent this list for themselves. Thanks.
