; This is a header file for the x264ASM assembly language, which uses
|
|
; NASM/YASM syntax combined with a large number of macros to provide easy
|
|
; abstraction between different calling conventions (x86_32, win64, linux64).
|
|
; It also has various other useful features to simplify writing the kind of
|
|
; DSP functions that are most often used in x264.
|
|
|
|
; Unlike the rest of x264, this file is available under an ISC license, as it
|
|
; has significant usefulness outside of x264 and we want it to be available
|
|
; to the largest audience possible. Of course, if you modify it for your own
|
|
; purposes to add a new feature, we strongly encourage contributing a patch
|
|
; as this feature might be useful for others as well. Send patches or ideas
|
|
; to x264-devel@videolan.org .

; 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

; I often want to use macros that permute their arguments. e.g. there's no
|
|
; efficient way to implement butterfly or transpose or dct without swapping some
|
|
; arguments.
|
|
;
|
|
; 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
