compute regex vs substr (v7)

Revision 7 of this benchmark created on

Description

http://stackoverflow.com/questions/11818896/how-do-i-make-an-anchored-regex-match-in-the-middle-of-a-string-in-javascript (edit 1) bugfix: don't substr in case 1. The RegExp moves the starting position.

Setup

var target = "foobar barse";
    
    var str_match = "bar";
    var pre_regex = /^bar/;
