Subject: [PATCH] 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.
