This updates our in-tree copy of libvpx to the v1.3.0 git tag (2e88f2f2ec777259bda1714e72f1ecd2519bceb5) libvpx 1.3.0 adds support for VP9. VP9 support is built but not yet exposed with this commit. Our update.sh script is replaced with update.py that can update the build system to a given git commit. - checkout out upstream git - create platform dependend config files - add/remove changed libvpx files - update moz.build - warn about new build categories in libvpx

; 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

; 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, and returns.
|
|
|
|
; 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
