The infrastructure required to support a programming language, startup and shutdown boilerplate, all the required functionality to support standard library features including integration points between language semantics and support code.
Stuff like what code runs before and after main(), trap handlers for floating point arithmetic, handling of thread local storage, bind language heap handling primitives to library code, traps for handling stack overflow errors,....
