[llvm-dev] Use Global ISel or SelectionDAG

[floris westermann via llvm-dev]

Hi llvm-dev,

I am currently writing a backend for an architecture I am designing in my
bachelor's thesis and recently came across the GlobalISel Selection
Framework.
Should already start using this over the more common Selection DAG?
Being new llvm backend development, I am not sure if GlobalISel would be
"easier" to implement than ISelDAG and if there is any decent documentation
on how to do so.

Cheers,
Floris
