This patch implements support for %C in dump_printf for dumping
cgraph_node *.
(I would have preferred to have a code for printing symtab_node *
and both subclasses, but there doesn't seem to be a good way for
-Wformat to handle inheritance, so, failing that, I went with
this approach).
gcc/c-family/ChangeLog:
* c-format.c (local_cgraph_node_ptr_node): New variable.
(gcc_dump_printf_char_table): Add entry for %C.
(get_pointer_to_named_type): New function, taken from the handling
code for "gimple *" from...
(init_dynamic_diag_info): ...here. Add handling for
"cgraph_node *".
* c-format.h (T_CGRAPH_NODE): New.
gcc/ChangeLog:
* dump-context.h (ASSERT_IS_CGRAPH_NODE): New macro.
* dumpfile.c (make_item_for_dump_cgraph_node): Move to before...
(dump_pretty_printer::decode_format): Implement "%C" for
cgraph_node *.
(selftest::test_capture_of_dump_calls): Rename "where" to
"stmt_loc". Convert test_decl to a function decl and set its
location. Add a symbol_table_test RAII instance and a
cgraph_node, using it to test "%C" and dump_symtab_node.
gcc/testsuite/ChangeLog:
* gcc.dg/format/gcc_diag-10.c (cgraph_node): New typedef.
(test_dump): Add testing of %C.
