Fix compat-table failures: Array.at, AnnexB if-decl, Proxy observable gets by lahma · Pull Request #2365 · sebastienros/jint (original) (raw)

… gets

• Fix Array.prototype.at() returning wrong value for negative out-of-bounds indices by changing ulong to long (C# casts negative double to ulong as 0)
• Fix AnnexB if-decl-else-decl with same function name in both branches by not adding to effectiveLexicalNames for IfStatement siblings
• Use RegExpCreate instead of RegExp.Construct in String.prototype.match/search to avoid extra IsRegExp call (observable Symbol.match access through Proxy)
• Remove observable sticky property read in RegExp.prototype[Symbol.replace] fast path by deriving from already-read flags string
• Fix String.prototype.split to use direct JsRegExp check instead of IsRegExp to avoid observable Symbol.match access
