/*
|
|
* Since regular expressions have been part of JavaScript since 1.2, there
|
|
* are already tests for regular expressions in the js1_2/regexp folder.
|
|
*
|
|
* These new tests try to supplement the existing tests, and verify that
|
|
* our implementation of RegExp conforms to the ECMA specification, but
|
|
* does not try to be as exhaustive as in previous tests.
|
|
*
|
|
* The [,limit] argument to String.split is new, and not covered in any
|
|
* existing tests.
|
|
*
|
|
* String.split cases are covered in ecma/String/15.5.4.8-*.js.
|
|
* String.split where separator is a RegExp are in
|
|
* js1_2/regexp/string_split.js
