From 2278363015a2a5cc850b38213833096d33b496e8 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Tue, 22 Sep 2009 18:12:39 -0700 Subject: slicc: Pure python implementation of slicc. This is simply a translation of the C++ slicc into python with very minimal reorganization of the code. The output can be verified as nearly identical by doing a "diff -wBur". Slicc can easily be run manually by using util/slicc --- src/mem/slicc/symbols/Symbol.py | 78 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 78 insertions(+) create mode 100644 src/mem/slicc/symbols/Symbol.py (limited to 'src/mem/slicc/symbols/Symbol.py') diff --git a/src/mem/slicc/symbols/Symbol.py b/src/mem/slicc/symbols/Symbol.py new file mode 100644 index 000000000..b394fda44 --- /dev/null +++ b/src/mem/slicc/symbols/Symbol.py @@ -0,0 +1,78 @@ +# Copyright (c) 1999-2008 Mark D.
