Description

We should generate inline code sequences for the most common cases of dynamic type checking in the baseline compilers implementation of instanceof/checkcast. In particular, if the LHS type is a resolved proper class or interface the inline sequence is actually smaller and easier to generate than the call to the out-of-line routines we are using now.
