I think neg_odd_64 was already applied.
Mostly added SSE2 versions, and fixed !PIC issues.

Christophe Gisquet (7):
  x86: sbrdsp: implement SSE/SSE2 qmf_pre_shuffle
  x86: sbrdsp: implement SSE qmf_deint_neg
  x86: sbrdsp: implement SSE qmf_deint_bfly
  x86: sbrdsp: implement SSE hf_apply_noise
  sbrdsp: unroll sbr_autocorrelate_c
  sbrdsp: unroll and use integer operations
  autocorrelate
