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

87 ; x86_32 doesn't require PIC.
88 ; Some distros prefer shared objects to be PIC, but nothing breaks if
89 ; the code contains a few textrels, so we'll skip that complexity.
96 ; Always use long nops (reduces 0x90 spam in disassembly on x86_32)
99 ; Macros to eliminate most code duplication between x86_32 and x86_64:
100 ; Currently this works only for leaf functions which load all their arguments
101 ; into registers at the start, and make no other use of the stack. Luckily that
102 ; covers most of x264's asm.
105 ; %1 = number of arguments. loads them from stack if needed.
106 ; %2 = number of registers used. pushes callee-saved regs if needed.
107 ; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
108 ; %4 = list of names to define to registers
109 ; PROLOGUE can also be invoked by adding the same options to cglobal
112 ; cglobal foo, 2,3,0, dst, src, tmp
113 ; declares a function (foo), taking two args (dst and src) and one local variable (tmp)
115 ; TODO Some functions can use some args directly from the stack. If they're the
116 ; last args then you can just not declare them, but if they're in the middle
117 ; we need more flexible macro.
120 ; Pops anything that was pushed by PROLOGUE, and returns.
123 ; Same, but if it doesn't pop anything it becomes a 2-byte ret, for athlons
124 ; which are slow when a normal ret follows a branch.
127 ; rN and rNq are the native-size register holding function argument N
128 ; rNd, rNw, rNb are dword, word, and byte size
129 ; rNh is the high 8 bits of the word size
130 ; rNm is the original location of arg N (a register or on the stack), dword
131 ; rNmp is native size
