Re: [Caml-list] Runtime overflow and what to do

Hi,

I am following the discussion. But do not understand this. Is this a
solution to eliminate overhead in integer arithmetic.

Personnally I thought to try to capture the overflow status flag for the
pentium processor on my Windows XP.

Thx

Scott

  The above can be reduced to one line, without temporary file.
  In fact, I feel more like we would need a "-silent" option, to get rid
  of prompts and types (this is already the default with scripts).

  echo "print_int Sys.word_size;;" | \
  ocaml | grep "^# ." | sed -e "s/# //" -e "s/- :.*//"

  A shorter but more specific approach is

  echo "Sys.word_size;;" | ocaml | grep "# -" | sed -e "s/.*= //"
