Re: RFC: fp printing speedup patch

[Paolo Carlini <pcarlini at unitus dot it>]

Hi Jerry. I'm just back and still trying to catch up...

Anyway, I have already printed the patch and was hoping to return
to you tomorrow or at most on monday.

Some things I can tell you immediately:

   1- For something so delicate (it affects the output of *most*
      programs!) we definitely must be *very* careful! You should
      post  *many* details about the tests you have done, perhaps
      many actual testcases too, for instance something like a loop
      generating random floats and comparing the output of the
      library to that of plain "C" printfs (using strings, of course
      for that).

   2- Some more numbers about performance: for sure it's a big
      improvement (thanks again) but which is still the gap wrt v2
      for some interesting examples (big number of digits/small
      number of digits)

   3- Due to 1-, above, I (we) would appreciate if you could outline
      a bit the algorithms used, the role of the dtoa thing, and so on.

If you want, I have time to help soon for 1- and also, I hope, for the
various configury issues, but I have to really allocate some time to
this in the next days.

More comments soon...

Paolo.

P.S. Later on, we should of course deal with the other uses of
    __convert_from_v, since the final goal is removing it completely.
