Enclosing class:

CalcRexImplementorTableImpl

private static class CalcRexImplementorTableImpl.AddCharSetNameInstrImplementor
extends CalcRexImplementorTableImpl.InstrDefImplementor

A Class that gets a specified operand of a call and retrieves its charset name and add it as a vc literal to the program. This of course assumes the operand is a chartype. If this is not the case an assert is fired.

Description copied from class: CalcRexImplementorTableImpl.InstrDefImplementor

Creates the list of registers which will be arguments to the instruction call. i.e implment all the operands of the call and create a result register for the call.

The 0th argument is assumed to hold the result of the call.
