Recently there were some articles which refered to Joshi-Dhamdhere

algorithm for Composite Hoisting and Strength Reduction. This is an old

paper and a new version of the same work was published in 1989. It seems

that researchers are unware of this later developement, hence I am posting

the reference:

@article{nchsa,

author = {D. M. Dhamdhere},

title = {A new algorithm for composite hoisting and strength reduction

optimization},

journal = {International Journal of Computer Mathematics},

volume = 27,

number = 1,

pages = {1--14},

year = 1989

*}*

However, this too is an old work (this is 1992 :-)); Some further work is

in progress at IIT Bombay. A new paper which eliminates some of the

drawbacks of nchsa(1989) is under preparation.

P.S. : Sometime back I had posted an article to gather information on

the use of bidirectional data flow problems in production compilers.

I got only one reply from Bill Leonard of Harris Computer Systems

Division which mentioned that the Harris Night Hawk compilers for C,

FORTRAN, and Ada use the Morel-Renvoise algorithm for CSE detection.

Are the bidirectional folks not tuned on, or is it that the interest

in bidirectional flows is its infacy ??? :-(
