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