* Add TYPE_EMPTY_RECORD for C++ empty classhjl/pr60336/x86H.J. Lu2016-02-1723-18/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Empty record should be returned and passed the same way in C and C++. This patch overloads a bit, side_effects_flag, in tree_base for C++ empty class. Middle-end and x86 backend are updated to ignore empty records for parameter passing and function value return. Other targets may need similar changes. get_ref_base_and_extent is changed to set bitsize to 0 for empty records so that when ref_maybe_used_by_call_p_1 calls get_ref_base_and_extent to get 0 as the maximum size on empty record. Otherwise, find_tail_calls won't perform tail call optimization for functions with empty record parameters, as shown in g++.dg/pr60336-1.C and g++.dg/pr60336-2.C. A new cxx target hook, function_skip_empty_class_p, is added, which defaults to return false. This ABI change is enabled only if the ABI level is at least 10, which is updated in GCC 6, and the target hook TARGET_CXX_FUNCTION_SKIP_EMPTY_CLASS_P returns true. gcc/ PR c++/60336 PR middle-end/67239 PR target/68355 * calls.c (initialize_argument_information): Warn empty record if they are used in a variable argument list or aren't the last arguments.
