; 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 = (optional) stack size to be allocated. If not aligned (x86-32 ICC 10.x, |
|
; MSVC or YMM), the stack will be manually aligned (to 16 or 32 bytes), |
|
; and an extra register will be allocated to hold the original stack |
|
; pointer (to not invalidate r0m etc.). To prevent the use of an extra |
|
; register as stack pointer, request a negative stack size. |
|
; %4+/%5+ = 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, and returns. |
|
|
|
; REP_RET: |
|
; Use this instead of RET if it's a branch target. |
|
|
|
; registers: |
|
; rN and rNq are the native-size register holding function argument N |
|
; rNd, rNw, rNb are dword, word, and byte size |
|
; rNh is the high 8 bits of the word size |
|
; rNm is the original location of arg N (a register or on the stack), dword |
|
; rNmp is native size |
