# 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.)
