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