This is not enough. As I commented earlier in
http://permalink.gmane.org/gmane.linux.bluez.kernel/31567
"neon code also provides optimized "sbc_enc_process_input_*" functions,
which are not going to work correctly for mSBC:
state->sbc_enc_process_input_8s_le = sbc_enc_process_input_8s_le_neon;
state->sbc_enc_process_input_8s_be = sbc_enc_process_input_8s_be_neon;"
And if we had, for example, an SSSE3 implementation of
"sbc_enc_process_input_*" functions for x86 (via PSHUFB instruction),
then it would also have the same problem.
