cp-tree.h (enum cp_lvalue_kind): Add clk_packed.
cp:
* cp-tree.h (enum cp_lvalue_kind): Add clk_packed.
* tree.c (lvalue_p_1): Set it.
* class.c (check_field): Don't allow non-packed non-POD fields to
be packed.
* call.c (reference_binding): Need a temporary for all bitfield
and packed fields.
(convert_like_real): Check it is ok to make a temporary here.
testsuite:
* g++.dg/ext/packed3.C: New test.
* g++.dg/ext/packed4.C: New test.
