Has anyone ever tried to implement lazy strength reduction for GCC?


Hello,

One of the suggestions Jeff made wrt. simplifying regmove, was that
some parts of it can be implemented more elegantly with the lazy
strength reduction algorithm, which is an extension of PRE as
implemented in GCC's gcse.c.

Has anyone ever tried implementing this for GCC?  Bonus if there's a
finished or unfinished patch that I could look at ;-)

Thanks,
Gr.

Steven
