# 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.)
