| * Date: 29 Oct 2002 |
| * SUMMARY: Testing "use" and "set" operations on expressions like a[i][j][k] |
| * See http://bugzilla.mozilla.org/show_bug.cgi?id=96526#c52 |
| * |
| * Brendan: "The idea is to cover all the 'use' and 'set' (as in modify) |
| * operations you can do on an expression like a[i][j][k], including variations |
| * where you replace |a| with arguments (literally) and |i| with 0, 1, 2, etc. |
| * (to hit the optimization for arguments[0]... that uses JSOP_ARGSUB)." |
