* bench.pl
|
|
A primitive Perl script to run benches. Currently its only bench is
|
|
the usual calculator: it has a lightweight processing part (but not
|
|
null), so it is really emphasizing the cost of the whole parsing
|
|
(including scanning and I/O).
|
|
|
|
Set the envvars BISON and CC to the programs and flags you want to
|
|
use. They default to bison and gcc. To run a non-installed bison
|
|
from a tarball built in _build, I suggest the following.
|
|
|
|
BISON=_build/tests/bison CC='gcc -O2' ./bench.pl
|
|
|
|
(The _build/tests/bison wrapper makes sure that _build/src/bison will
|
|
use the tarballs' skeletons, not those already installed as a
|
|
straightforward use of _build/src/bison would.)
