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/ast/PeekStatementAST.cc | 115 ---------------------------------- 1 file changed, 115 deletions(-) delete mode 100644 src/mem/slicc/ast/PeekStatementAST.cc (limited to 'src/mem/slicc/ast/PeekStatementAST.cc') diff --git a/src/mem/slicc/ast/PeekStatementAST.cc b/src/mem/slicc/ast/PeekStatementAST.cc deleted file mode 100644 index 3e92446dd..000000000 --- a/src/mem/slicc/ast/PeekStatementAST.cc +++ /dev/null @@ -1,115 +0,0 @@ - -/* - * Copyright (c) 1999-2008 Mark D.
