No, but you can ask questions here. I've done some minor x86_64
assembler work for image processing. Things like format conversions,
uniform lighting, rotate, erosion/dilation etc.
Thanks for offering. I am particularly interested in knowing the
tricks that can be done with masking, e.g. to prevent branching. In
the first place to get an idea what can be done with vector code and
what not. I guess I should read the Intel and AMD processor docs first.
Well, saturation often avoids branches, as well as built in min/max
instructions.
pcmpgtb and friends are kind of the x86 setcc like instructions. Store
the result of a comparison(s) to a register.
