| # 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.) |
