#ifndef SPU_SHUFFLE_H
#define SPU_SHUFFLE_H
/*
* Generate shuffle patterns with minimal fuss.
*
* Based on ideas from
* http://www.insomniacgames.com/tech/articles/0408/files/shuffles.pdf
*
* A-P indicates 0-15th position in first vector
* a-p indicates 0-15th position in second vector
*
* +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
* |00|01|02|03|04|05|06|07|08|09|0a|0b|0c|0d|0e|0f|
* +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
* | A| B| C| D|
* +-----+-----+-----+-----+-----+-----+-----+-----+
* | A| B| C| D| E| F| G| H|
* +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
* | A| B| C| D| E| F| G| H| I| J| K| L| M| N| O| P|
* +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
*
* x or X indicates 0xff
* 8 indicates 0x80
* 0 indicates 0x00
*
* The macros SHUFFLE4() SHUFFLE8() and SHUFFLE16() provide a const vector
* unsigned char literal suitable for use with spu_shuffle().
*
* The macros SHUFB4() SHUFB8() and SHUFB16() provide a const qword vector
* literal suitable for use with si_shufb().
*
*
* For example :
* SHUFB4(A,A,A,A)
* expands to :
* ((const qword){0,1,2,3,0,1,2,3,0,1,2,3,0,1,2,3})
*
* SHUFFLE8(A,B,a,b,C,c,8,8)
* expands to :
* ((const vector unsigned char){0x00,0x01,0x02,0x03,0x10,0x11,0x12,0x13,
* 0x04,0x05,0x14,0x15,0xe0,0xe0,0xe0,0xe0})
