+ * and produces exactly the same output as IJG's original 'jpeg_idct_ifast'
+ * function from jidctfst.c
+ *
+ * Normally 1-D AAN DCT needs 5 multiplications and 29 additions.
+ * But in Arm Neon case some extra additions are required because VQDMULH
+ * instruction can't handle the constants larger than 1. So the expressions
+ * like "x * 1.082392200" have to be converted to "x * 0.082392200 + x",
+ * which introduces an extra addition. Overall, there are 6 extra additions
+ * per 1-D IDCT pass, totalling to 5 VQDMULH and 35 VADD/VSUB instructions.

+ * Samples s0A-s2C were created by averaging the original pixel component
+ * values centered at positions p0-p35 above. To approximate one of those
+ * original pixel component values, we proportionally blend the sample
+ * containing the pixel center with the nearest neighboring samples in each
+ * row, column, and diagonal.
+ *
+ * An upsampled pixel component value is computed by first blending the sample
+ * containing the pixel center with the nearest neighboring samples in the
+ * same column, in the ratio 3:1, and then blending each column sum with the
+ * nearest neighboring column sum, in the ratio 3:1. For example:
+ * p14(upsampled) = 3/4 * (3/4 * s1B + 1/4 * s1A) +
+ * 1/4 * (3/4 * s0B + 1/4 * s0A)
+ * = 9/16 * s1B + 3/16 * s1A + 3/16 * s0B + 1/16 * s0A
+ * When computing the first and last pixel component values in the row, there
+ * is no horizontally adjacent sample to blend, so:
+ * p12(upsampled) = 3/4 * s0B + 1/4 * s0A
+ * p23(upsampled) = 3/4 * s2B + 1/4 * s2C
+ * When computing the first and last pixel component values in the column,
+ * there is no vertically adjacent sample to blend, so:
+ * p2(upsampled) = 3/4 * s1A + 1/4 * s0A
+ * p33(upsampled) = 3/4 * s1C + 1/4 * s2C
+ * When computing the corner pixel component values, there is no adjacent
+ * sample to blend, so:
+ * p0(upsampled) = s0A
+ * p35(upsampled) = s2C

+ *
+ * Optimization techniques used for fast data access:
+ *
+ * In each pass, the inverse DCT is computed for the left and right 4x8 halves
+ * of the DCT block. This avoids spilling due to register pressure, and the
+ * increased granularity allows for an optimized calculation depending on the
+ * values of the DCT coefficients. Between passes, intermediate data is stored
+ * in 4x8 workspace buffers.
+ *
+ * Transposing the 8x8 DCT block after each pass can be achieved by transposing
+ * each of the four 4x4 quadrants and swapping quadrants 1 and 2 (refer to the
+ * diagram below.) Swapping quadrants is cheap, since the second pass can just
+ * swap the workspace buffer pointers.
+ *
+ * +-------+-------+ +-------+-------+
+ * | | | | | |

+ * | | | | | |
+ * +-------+-------+ +-------+-------+
+ *
+ * Optimization techniques used to accelerate the inverse DCT calculation:
+ *
+ * In a DCT coefficient block, the coefficients are increasingly likely to be 0
+ * as you move diagonally from top left to bottom right. If whole rows of
+ * coefficients are 0, then the inverse DCT calculation can be simplified. On
+ * the first pass of the inverse DCT, we test for three special cases before
+ * defaulting to a full "regular" inverse DCT:
+ *
+ * 1) Coefficients in rows 4-7 are all zero. In this case, we perform a
+ * "sparse" simplified inverse DCT on rows 0-3.
+ * 2) AC coefficients (rows 1-7) are all zero. In this case, the inverse DCT
+ * result is equal to the dequantized DC coefficients.
+ * 3) AC and DC coefficients are all zero. In this case, the inverse DCT
+ * result is all zero. For the left 4x8 half, this is handled identically
+ * to Case 2 above. For the right 4x8 half, we do no work and signal that
+ * the "sparse" algorithm is required for the second pass.
+ *
+ * In the second pass, only a single special case is tested: whether the AC and
+ * DC coefficients were all zero in the right 4x8 block during the first pass
+ * (refer to Case 3 above.) If this is the case, then a "sparse" variant of
+ * the second pass is performed for both the left and right halves of the DCT
+ * block. (The transposition after the first pass means that the right 4x8
+ * block during the first pass becomes rows 4-7 during the second pass.)

+; Shorthand used to describe SIMD operations:
+; wN: xmmN treated as eight signed 16-bit values
+; wN[i]: perform the same operation on all eight signed 16-bit values, i=0..7
+; bN: xmmN treated as 16 unsigned 8-bit values, or

+; Contents of SIMD registers are shown in memory order.
+
+; Fill the bit buffer to capacity with the leading bits from code, then output
+; the bit buffer and put the remaining bits from code into the bit buffer.
+;
+; Usage:
+; code - contains the bits to shift into the bit buffer (LSB-aligned)
+; %1 - temp register
+; %2 - low byte of temp register
+; %3 - second byte of temp register
+; %4-%8 (optional) - extra instructions to execute before the macro completes
+; %9 - the label to which to jump when the macro completes
+;
+; Upon completion, free_bits will be set to the number of remaining bits from
+; code, and put_buffer will contain those remaining bits. temp and code will
+; be clobbered.
+;
+; This macro encodes any 0xFF bytes as 0xFF 0x00, as does the EMIT_BYTE()
+; macro in jchuff.c.

+;
+; NOTES:
+; When shuffling data, we try to avoid pinsrw as much as possible, since it is
+; slow on many CPUs. Its reciprocal throughput (issue latency) is 1 even on
+; modern CPUs, so chains of pinsrw instructions (even with different outputs)
+; can limit performance. pinsrw is a VectorPath instruction on AMD K8 and
+; requires 2 µops (with memory operand) on Intel. In either case, only one
+; pinsrw instruction can be decoded per cycle (and nothing else if they are
+; back-to-back), so out-of-order execution cannot be used to work around long
+; pinsrw chains (though for Sandy Bridge and later, this may be less of a
+; problem if the code runs from the µop cache.)
+;
+; We use tzcnt instead of bsf without checking for support. The instruction is
+; executed as bsf on CPUs that don't support tzcnt (encoding is equivalent to
+; rep bsf.) The destination (first) operand of bsf (and tzcnt on some CPUs) is
+; an input dependency (although the behavior is not formally defined, Intel
+; CPUs usually leave the destination unmodified if the source is zero.) This
+; can prevent out-of-order execution, so we clear the destination before
+; invoking tzcnt.

+ ;
+ ; - The second operand for the shifts is not treated as packed.
+ ;
+ ;
+ ; We work around the first problem by implementing this algorithm:

+ ; signed short sx = (signed short)x;

+ ; if (sy < 0) sz += (long)sx << SHORT_BIT;
+ ;
+ ; return (unsigned long)sz;
+ ; }
+ ;
+ ; (note that a negative sx adds _sy_ and vice versa)
+ ;
+ ; For the second problem, we replace the shift by a multiplication.

+; NOTES:
+; When shuffling data, we try to avoid pinsrw as much as possible, since it is
+; slow on many CPUs. Its reciprocal throughput (issue latency) is 1 even on
+; modern CPUs, so chains of pinsrw instructions (even with different outputs)
+; can limit performance. pinsrw is a VectorPath instruction on AMD K8 and
+; requires 2 µops (with memory operand) on Intel. In either case, only one
+; pinsrw instruction can be decoded per cycle (and nothing else if they are
+; back-to-back), so out-of-order execution cannot be used to work around long
+; pinsrw chains (though for Sandy Bridge and later, this may be less of a
+; problem if the code runs from the µop cache.)

+; We use tzcnt instead of bsf without checking for support. The instruction is
+; executed as bsf on CPUs that don't support tzcnt (encoding is equivalent to
+; rep bsf.) The destination (first) operand of bsf (and tzcnt on some CPUs) is
+; an input dependency (although the behavior is not formally defined, Intel
+; CPUs usually leave the destination unmodified if the source is zero.) This
+; can prevent out-of-order execution, so we clear the destination before
+; invoking tzcnt.
