; 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

; Currently this works only for leaf functions which load all their arguments

; 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.

; Pops anything that was pushed by PROLOGUE

 | 
						|
; which are slow when a normal ret follows a branch.
