* Make special cases (0 inf nan) work for frem.Dale Johannesen2009-01-215-38/+384

| | | | | | | | | | | | | | | SDNode subclasses to keep state that requires non-trivial destructors, however it was already effectively impossible, since the destructor isn't actually ever called. There currently aren't any SDNode subclasses affected by this, and in general it's desireable to keep SDNode objects light-weight. This eliminates the last virtual member function in the SDNode class, so it eliminates the need for a vtable pointer, making SDNode smaller. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62539 91177308-0d34-0410-b5e6-96231b3b80d8
