1 * bench.pl 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). 6 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. 10 11 BISON=_build/tests/bison CC='gcc -O2' ./bench.pl 12 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.) 16 17 -- 18 19 Copyright (C) 2006, 2009-2012 Free Software Foundation, Inc. 20 21 This file is part of Bison, the GNU Compiler Compiler. 22 23 This program is free software: you can redistribute it and/or modify 24 it under the terms of the GNU General Public License as published by 25 the Free Software Foundation, either version 3 of the License, or 26 (at your option) any later version. 27 28 This program is distributed in the hope that it will be useful, 29 but WITHOUT ANY WARRANTY; without even the implied warranty of 30 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
