Here is one:


F. Chow, M. Himelstein, E. Killian, L. Weber: Engineering a RISC compiler
system, Digest of Papers of the Thirtyfirst IEEE Computer Society
International Conference (CompCon 86 Spring), February 1986, pp. 132-137.


It describes the MIPS C compiler which has the optimization you mentioned.
