-// The reason that interpreter initialization is split into two parts is that the first part
-// needs to run before methods are loaded (which with CDS implies linked also), and the other
-// part needs to run after. The reason is that when methods are loaded (with CDS) or linked
-// (without CDS), the i2c adapters are generated that assert we are currently in the interpreter.
-// Asserting that requires knowledge about where the interpreter is in memory. Therefore,
-// establishing the interpreter address must be done before methods are loaded. However,
-// we would like to actually generate the interpreter after methods are loaded. That allows
-// us to remove otherwise hardcoded offsets regarding fields that are needed in the interpreter
-// code. This leads to a split if 1. reserving the memory for the interpreter, 2. loading methods
-// and 3. generating the interpreter.
