ff_sws_shuffle_mask()

int ff_sws_shuffle_mask	(	const SwsUOp *	uop,

Compute a shuffle mask for pshufb-style ASM functions, by repeating the shuffle pattern for as many groups as will fit.

Parameters

uop	An operation of type SWS_UOP_RW_SHUFFLE.
shuffle	The output shuffle index mask (or -1 to clear bytes).
size	The maximum size (in bytes) of the output shuffle mask.

Returns

the number of groups on success, or a negative error code.

Note

The shuffle mask is already pre-expanded to fill up to 16 bytes, so this is only needed for larger shuffle instructions (e.g. vpermb).
