   1 * bench.pl
   2 A primitive Perl script to run benches.  Currently its only bench is
   3 the usual calculator: it has a lightweight processing part (but not
   4 null), so it is really emphasizing the cost of the whole parsing
   5 (including scanning and I/O).

   7 Set the envvars BISON and CC to the programs and flags you want to
   8 use.  They default to bison and gcc.  To run a non-installed bison
   9 from a tarball built in _build, I suggest the following.
  10
  11      BISON=_build/tests/bison CC='gcc -O2' ./bench.pl
  12
  13 (The _build/tests/bison wrapper makes sure that _build/src/bison will
  14 use the tarballs' skeletons, not those already installed as a
  15 straightforward use of _build/src/bison would.)
