Using inline assembler

[Etienne via Digitalmars-d-learn]

Maybe someone can help with the more specific problem. I'm translating a 
crypto engine here:

https://github.com/etcimon/botan/blob/master/source/botan/block/aes_ni/aes_ni.d

But I need this to work on DMD, LDC and GDC. I decided to write the 
assembler code directly for the functions in this module:

https://github.com/etcimon/botan/blob/master/source/botan/utils/simd/xmmintrin.d

If there's anything someone can tell me about this, I'd be thankful. I'm 
very experienced in every aspect of programming, but still at my first 
baby steps in assembler.
