This change set includes tests for most invocations of the SetFunctionName abstract operation in the ES2015 specification. Practical testing considerations preclude the introduction of tests for certain invocations: - The project is still vetting methods to sustainably test the semantics of the Destructuring Binding pattern across all valid productions. - 13.3.3.6 Runtime Semantics: IteratorBindingInitialization - 13.3.3.7 Runtime Semantics: KeyedBindingInitialization - Without a loader, there is no way to access a function object declared in an ExportDeclaration, so `name` assignment cannot be tested in these cases - 14.1.19 Runtime Semantics: InstantiateFunctionObject - 14.4.12 Runtime Semantics: InstantiateFunctionObject - 14.5.15 Runtime Semantics: BindingClassDeclarationEvaluation - 15.2.3.11 Runtime Semantics: Evaluation

description: Left-hand side as a CoverParenthesizedExpression

info: >
|

AssignmentExpression[In, Yield] :
|
|
LeftHandSideExpression[?Yield] = AssignmentExpression[?In, ?Yield]
|
|
|
|
1. If LeftHandSideExpression is neither an ObjectLiteral nor an
|
|
ArrayLiteral, then
|
|
[...]
|
|
e. If IsAnonymousFunctionDefinition(AssignmentExpression) and
|
|
IsIdentifierRef of LeftHandSideExpression are both true, then
|
|
|
|
i. Let hasNameProperty be HasOwnProperty(rval, "name").
|
|
ii. ReturnIfAbrupt(hasNameProperty).
|
|
iii. If hasNameProperty is false, perform SetFunctionName(rval,
|
|
GetReferencedName(lref)).
