Subject: Add a script for converting ads arm assembly to microsoft armasm format
X-Git-Tag: v1.3.0~1122^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a83db43632ba99c4232a059d2b1c9266c99886d2;p=libvpx

Add a script for converting ads arm assembly to microsoft armasm format

The formats are basically the same, but a few minor details need
to be adjusted. Addiitonally, when building for the WinRT/Windows
Phone 8 platforms, one has to build for thumb, so convert instructions
accordingly.
