This adds support for the C++11 "enum class" feature. This is PR c++/15246. I chose to use the existing TYPE_DECLARED_CLASS rather than introduce a new type code. This seemed both simple and clear to me. I made overloading support for the new enum types strict. This is how it works in C++; and it didn't seem like an undue burden to keep this, particularly because enum constants are printed symbolically by gdb. Built and regtested on x86-64 Fedora 20. 2014-04-14 Tom Tromey <tromey@redhat.com> PR c++/15246: * c-exp.y (type_aggregate_p): New function. (qualified_name, classify_inner_name): Use it. * c-typeprint.c (c_type_print_base): Handle TYPE_DECLARED_CLASS and TYPE_TARGET_TYPE of an enum type. * dwarf2read.c (read_enumeration_type): Set TYPE_DECLARED_CLASS on an enum type. (determine_prefix) <case DW_TAG_enumeration_type>: New case; handle TYPE_DECLARED_CLASS. * gdbtypes.c (rank_one_type): Handle TYPE_DECLARED_CLASS on enum types. * gdbtypes.h (TYPE_DECLARED_CLASS): Update comment. * valops.c (enum_constant_from_type): New function.
