uint8_t DSPContext::idct_permutation[64]

idct input permutation.

several optimized IDCTs need a permutated input (relative to the normal order of the reference IDCT) this permutation must be performed before the idct_put/add, note, normally this can be merged with the zigzag/alternate scan
an example to avoid confusion:

(->decode coeffs -> zigzag reorder -> dequant -> reference idct ->...)
(x -> reference dct -> reference idct -> x)
(x -> reference dct -> simple_mmx_perm = idct_permutation -> simple_idct_mmx -> x)
(->decode coeffs -> zigzag reorder -> simple_mmx_perm -> dequant -> simple_idct_mmx ->...)
