- Purpose:
- abstract base class of comiler IR code builder
-
- Notes:
- All "CG_outputRepr *" parameters are consumed inside the the function
- unless explicitly stated otherwise, i.e., not valid after the call.
- Parameter "indent" normally not used except it is used in unstructured
- string output for correct indentation.

- 04/17/96 created - Lei Zhou
- 05/02/08 clarify integer floor/mod/ceil definitions, -chen
- 05/31/08 use virtual clone to implement CreateCopy, -chun
- 08/05/10 clarify NULL parameter allowance, -chun
