From: Reid Kleckner Date: Wed, 31 Aug 2016 15:59:30 +0000 (+0000) Subject: [codeview] Emit vtable shape information X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9dac47319d29430e6fc6e04d2839e0f2c45dffac;p=platform%2Fupstream%2Fllvm.git [codeview] Emit vtable shape information The shape of the vtable is passed down as the size of the __vtbl_ptr_type. This special pointer type appears both as the pointee type of the vptr type, and by itself in every dynamic class. For classes with multiple vtables, only the shape of the primary vftable is included, as the shape of all secondary vftables will be the same as in the base class.
