| 9 * SUMMARY: Testing script with at least 64K of different string literals | |
| 10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334 | |
| 11 * | |
| 12 * Testing that script engine can handle scripts with at least 64K of different | |
| 13 * string literals. The following will evaluate, via eval(), a script like this: | |
| 14 * | |
| 15 * f('0') | |
| 16 * f('1') | |
| 17 * ... | |
| 18 * f('N - 1') | |
| 19 * | |
| 20 * where N is 0xFFFE | |
| 21 * | |
