Tom Hvitved	5ce9b25ec9	C#: Improve CFG for assignments ... Write accesses in assignments, such as the access to `x` in `x = 0` are not evaluated, so they should not have entries in the control flow graph. However, qualifiers (and indexer arguments) should still be evaluated, for example in ``` x.Foo.Bar = 0; ``` the CFG should be `x --> x.Foo --> 0 --> x.Foo.Bar = 0` (as opposed to `x --> x.Foo --> x.Foo.Bar --> 0 --> x.Foo.Bar = 0`, prior to this change). A special case is assignments via acessors (properties, indexers, and event adders), where we do want to include the access in the control flow graph, as it represents the accessor call: ``` x.Prop = 0; ``` But instead of `x --> x.set_Prop --> 0 --> x.Prop = 0` the CFG should be `x --> 0 --> x.set_Prop --> x.Prop = 0`, as the setter is called *after* the assigned value has been evaluated. An even more special case is tuple assignments via accessors: ``` (x.Prop1, y.Prop2) = (0, 1); ``` Here the CFG should be `x --> y --> 0 --> 1 --> x.set_Prop1 --> y.set_Prop2 --> (x.Prop1, y.Prop2) = (0, 1)`.	2019-02-16 19:19:24 +01:00
