* ALAC (Apple Lossless Audio Codec) decoder
* @author 2005 David Hammerton
*
* For more information on the ALAC format, visit:
* http://crazney.net/programs/itunes/alac.html
*
* Note: This decoder expects a 36- (0x24-)byte QuickTime atom to be
* passed through the extradata[_size] fields. This atom is tacked onto
* the end of an 'alac' stsd atom and has the following format:
* bytes 0-3 atom size (0x24), big-endian
* bytes 4-7 atom type ('alac', not the 'alac' tag from start of stsd)
* bytes 8-35 data bytes needed by decoder
*
* Extradata:
* 32bit size
* 32bit tag (=alac)
* 32bit zero?
* 32bit max sample per frame
* 8bit ?? (zero?)
* 8bit sample size
* 8bit history mult
* 8bit initial history
* 8bit kmodifier
* 8bit channels?
* 16bit ??
* 32bit max coded frame size
* 32bit bitrate?
* 32bit samplerate

We can suppose that result of two multiplications can't be greater than 0xFFFF
i.e. is 16-bit, so we use here only PMULLW instruction and can avoid
a complex multiplication.
=====================================================
Full formula for multiplication of 2 integer numbers
which are represent as high:low words:
input: value1 = high1:low1
value2 = high2:low2
output: value3 = value1*value2
value3=high3:low3 (on overflow: modulus 2^32 wrap-around)
this mean that for 0x123456 * 0x123456 correct result is 0x766cb0ce4
but this algorithm will compute only 0x66cb0ce4
this limited by 16-bit size of operands
---------------------------------
tlow1 = high1*low2
tlow2 = high2*low1
tlow1 = tlow1 + tlow2
high3:low3 = low1*low2
high3 += tlow1

; This is true in practice (since we never do any 64bit arithmetic on strides,
; and x264's strides are all positive), but is not guaranteed by the ABI.
; Name of the .rodata section.

; x86_64 can't fit 64bit address literals in most instruction types,

; in memory) must use an address mode that does fit.
; So all accesses to global variables must use this macro, e.g.
; mov eax, [foo GLOBAL]
; instead of
; mov eax, [foo]
;
; x86_32 doesn't require PIC.
; Some distros prefer shared objects to be PIC, but nothing breaks if
; the code contains a few textrels, so we'll skip that complexity.

; Macros to eliminate most code duplication between x86_32 and x86_64:
; Currently this works only for leaf functions which load all their arguments
; into registers at the start, and make no other use of the stack. Luckily that
; covers most of x264's asm.
; PROLOGUE:
; %1 = number of arguments. loads them from stack if needed.
; %2 = number of registers used. pushes callee-saved regs if needed.
; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
; %4 = list of names to define to registers
; PROLOGUE can also be invoked by adding the same options to cglobal
; e.g.
; cglobal foo, 2,3,0, dst, src, tmp
; declares a function (foo), taking two args (dst and src) and one local variable (tmp)
; TODO Some functions can use some args directly from the stack. If they're the
; last args then you can just not declare them, but if they're in the middle
; we need more flexible macro.
; RET:
; Pops anything that was pushed by PROLOGUE
; REP_RET:
; Same, but if it doesn't pop anything it becomes a 2-byte ret, for athlons
; which are slow when a normal ret follows a branch.
; registers:
; rN and rNq are the native-size register holding function argument N
; rNd, rNw, rNb are dword, word, and byte size
; rNm is the original location of arg N (a register or on the stack), dword
; rNmp is native size

; I would like to not have to manually keep track of the permutations:
; If I insert a permutation in the middle of a function, it should automatically
; change everything that follows. For more complex macros I may also have multiple
; implementations, e.g. the SSE2 and SSSE3 versions may have different permutations.
;
; Hence these macros. Insert a PERMUTE or some SWAPs at the end of a macro that
; permutes its arguments. It's equivalent to exchanging the contents of the
; registers, except that this way you exchange the register names instead, so it
; doesn't cost any cycles.
%macro PERMUTE 2-* ; takes a list of pairs to swap
%rep %0/2

%rep %0-1

CAT_XDEFINE n, m%1, %1

; If we were called as "SWAP m0,m1" rather than "SWAP 0,1" infer the original numbers here.
; Be careful using this mode in nested macros though, as in some cases there may be
; other copies of m# that have already been dereferenced and don't get updated correctly.

/* Bitstream description
* The picture is divided into blocks that are zlib compressed.
*
* The decoder is fed complete frames, the frameheader contains:
* 4bits of block width
* 12bits of frame width
* 4bits of block height
* 12bits of frame height
*
* Directly after the header are the compressed blocks. The blocks
* have their compressed size represented with 16bits in the beginnig.
* If the size = 0 then the block is unchanged from the previous frame.
* All blocks are decompressed until the buffer is consumed.
*
* Encoding ideas, a basic encoder would just use a fixed block size.
* Block sizes can be multipels of 16, from 16 to 256. The blocks don't
* have to be quadratic. A brute force search with a set of diffrent
* block sizes should give a better result then to just use a fixed size.
