public class FinalMIRExpansion extends IRTools
One job of this phase is to handle the expansion of the remains of
table switch. The code looks like a mess (which it is), but there
is little choice for relocatable IA32 code that does this. And the
details of this code are shared with the baseline compiler and
dependent in detail on the Assembler (see Assembler.emitOFFSET_Imm_ImmOrLabel(int, int, int)). If you want to mess with
it, you will probably need to mess with them as well.
