| 10 * SUMMARY: Passing (RegExp object, flag) to RegExp() function. | |
| 11 * This test arose from Bugzilla bug 61266. The ECMA3 section is: | |
| 12 * | |
| 13 * 15.10.3 The RegExp Constructor Called as a Function | |
| 14 * | |
| 15 * 15.10.3.1 RegExp(pattern, flags) | |
| 16 * | |
| 17 * If pattern is an object R whose [[Class]] property is "RegExp" | |
| 18 * and flags is undefined, then return R unchanged. Otherwise | |
| 19 * call the RegExp constructor (section 15.10.4.1), passing it the | |
| 20 * pattern and flags arguments and return the object constructed | |
| 21 * by that constructor. | |
| 22 * | |
| 23 * | |
| 24 * The current test will check the first scenario outlined above: | |
| 25 * | |
| 26 * "pattern" is itself a RegExp object R | |
| 27 * "flags" is undefined | |
| 28 * | |
| 29 * This test is identical to test 15.10.3.1-1.js, except here we do: | |
| 30 * | |
| 31 * RegExp(R, undefined); | |
| 32 * | |
| 33 * instead of: | |
| 34 * | |
| 35 * RegExp(R); | |
| 36 * | |
| 37 * | |
| 38 * We check that RegExp(R, undefined) returns R - | |
