Re. comment #5 -- rth, any suggestions what an algorithm would look like to
"minimize the number of branches, or the total size of all of the branch
instructions"? And what do you mean with "some clever changes to the
shorten_branches code"? Did you mean the calculation of insn sizes, or
avoiding padding, or something else completely? Hope you can help a bit...
