I'm looking for statistics about what proportion of instructions use as
operands the results of immediately preceding instructions, preferably for
optimally reordered code and subdivided into loads and computes.  I want to
compute the benefit of various forms of register forwarding.

Does anyone have these figures, or references to where I can find them ?

Many thanks,

--Phil.
