1287522 - Wrong evaluation order in RegExp.prototype.toString

Status: RESOLVED FIXED

(Core :: JavaScript: Standard Library, defect)

Description

[André Bargull [:anba]]

ToString needs to be applied before retrieving the "flags" property.


Test case:
---
RegExp.prototype.toString.call({
  get source() {
    print("get source");
    return {toString() {print("source-tostring")}};
  },
  get flags() {
    print("get flags");
    return {toString() {print("flags-tostring")}};
  },
});
---

Expected: Prints "source-tostring" before "get flags"
Actual: Prints "source-tostring" after "get flags"

Attachment: Apply ToString in correct order in RegExp.prototype.toString.

Added explicit ToString call to pattern and flags, in correct order, and renumbered the spec steps.
