So basically their is room to improve our assembly code for various target. How do you plan to proceed ? Add a dependency or move the useful code inside of Evas ? Also did you do any comparison on why our assembly and their assembly have different profile. I am wondering if we need to use all of libyuv code or if only a part of it is interesting to us by complementing our current assemblty code. -- Cedric BAIL ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
