| 2 * Unfortunately the code we got from ETSI makes heavy use of two global | |
| 3 * Boolean flags named Carry and Overflow that function like equally named | |
| 4 * processor state flags on many CPU architectures. They are not part | |
| 5 * of persistent codec session state for either the encoder or the decoder, | |
| 6 * instead they are "short-term" globals much like UNIX errno. | |
| 7 * | |
| 8 * Given this unfortunate reality plus the natural desire to make our | |
| 9 * AMR library thread-safe (a transcoding MGW handling a large volume of | |
| 10 * simultaneous calls is exactly the kind of application that would benefit | |
| 11 * from utilitizing all CPU cores), our current workaround is to use | |
| 12 * thread-local storage. | |
