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.
11 BISON=_build/tests/bison CC='gcc -O2' ./bench.pl
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.)
