| 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. | |
| 29 | |
| 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 . | |

| 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 | |

| 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 | |
| 110 | |
| 111 ; e.g. | |
| 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) | |
| 114 | |
| 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. | |
