+description: Variable binding value is updated following evaluation (IfStatement with a declaration in both statement positions in the global scope)
+esid: sec-functiondeclarations-in-ifstatement-statement-clauses
+flags: [generated, noStrict]
+info: |
+    The following rules for IfStatement augment those in 13.6:
+
+    IfStatement[Yield, Return]:
+        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return]
+        if ( Expression[In, ?Yield] ) Statement[?Yield, ?Return] else FunctionDeclaration[?Yield]
+        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
+        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]
+
+
+    B.3.3.2 Changes to GlobalDeclarationInstantiation
+
+    [...]
+    e. When the FunctionDeclaration f is evaluated, perform the following steps
+       in place of the FunctionDeclaration Evaluation algorithm provided in
+       14.1.21:
+       i. Let genv be the running execution context's VariableEnvironment.
+       ii. Let genvRec be genv's EnvironmentRecord.
+       iii. Let benv be the running execution context's LexicalEnvironment.
+       iv. Let benvRec be benv's EnvironmentRecord.
+       v. Let fobj be ! benvRec.GetBindingValue(F, false).
+       vi. Perform ? genvRec.SetMutableBinding(F, fobj, false).
+       vii. Return NormalCompletion(empty).
