1.11 + File Name: 11.10-3.js
1.12 + ECMA Section: 11.10-3 Binary Bitwise Operators: ^
1.13 + Description:
1.14 + Semantics
1.15 +
1.16 + The production A : A @ B, where @ is one of the bitwise operators in the
1.17 + productions &, ^, | , is evaluated as follows:
1.18 +
1.19 + 1. Evaluate A.
1.20 + 2. Call GetValue(Result(1)).
1.21 + 3. Evaluate B.
1.22 + 4. Call GetValue(Result(3)).
1.23 + 5. Call ToInt32(Result(2)).
1.24 + 6. Call ToInt32(Result(4)).
1.25 + 7. Apply the bitwise operator @ to Result(5) and Result(6). The result is
1.26 + a signed 32 bit integer.
1.27 + 8. Return Result(7).
