libgsmhr1/dec_func.c: rm unused static functions
In the original code, sp_dec.c held two kinds of functions: those
needed only as part of the decoder, and those used by both decoder
and encoder engines. In this library, we have moved the latter
class of functions to dec_func.c module. Almost all static functions
from the original sp_dec.c, with the exception of aToRc(), are
needed only on sp_dec.c side of the new divide - remove them from
dec_func.c, where they became dead code.

/* * The function implemented in this module is an aid for AMR-EFR interworking; * it is meant to be invoked directly after amr_encode_frame(). It checks * the encoder output for MR122 DHF and turns it into EFR DHF just like * amr_dhf_subst_efr(), but only if the input PCM frame was an EHF. This * slightly more complicated logic is needed in order to replicate the observed * behavior of AMR-EFR speech encoder in the extant GSM network of T-Mobile USA. */ #include "tw_amr.h" #include "namespace.h" #include "e_homing.h" void amr_dhf_subst_efr2(struct amr_param_frame *frame, const int16_t *pcm) { if (encoder_homing_frame_test(pcm)) amr_dhf_subst_efr(frame); }
