Convert parse_tree_indirect to take a pointer to struct object_id. Update all the callers. This transformation was achieved using the following semantic patch and manual updates to the declaration and definition. Update builtin/checkout.c manually as well, since it uses a ternary expression not handled by the semantic patch. @@ expression E1; @@ - parse_tree_indirect(E1.hash) + parse_tree_indirect(&E1) @@ expression E1; @@ - parse_tree_indirect(E1->hash) + parse_tree_indirect(E1) Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
