From 3d567982aca11c85a7fa31f13046de3271d3afc8 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 27 Mar 2014 12:24:27 -0600 Subject: implement support for "enum class" 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 PR c++/15246: * c-exp.y (type_aggregate_p): New function.
