trying to understand inlining

[Thomas Wuerthinger]

Graal does not (yet) support invokedynamic. At the moment we are more 
focused on support for multi-language execution that goes beyond adding 
a new Java bytecode. We plan to present our research results in this 
area at this year's JVM language summit.

The two interfaces InliningPolicy and WeightComputationPolicy are 
definitely a good place to start when experimenting with customized 
inlining. Generally, changes of those policies have a big influence on 
our benchmark results (both for Java and Scala). You can also make a 
custom compiler phase (by extending the Phase class) that performs 
certain inlines manually (e.g., by calling InliningUtil.inline).
