From 8f9f0f97804eb461ac2397403f5e128578ba15a2 Mon Sep 17 00:00:00 2001 From: Zvonimir Date: Mon, 17 Nov 2014 17:59:55 -0700 Subject: [PATCH 001/187] Bug fix. Assignments created from PHI nodes should be done in parallel. Here is an example of multiple PHI assignments that Shaobo discovered are causing problems: p4 := p8; p5 := p4; // this p4 here should refer to p4 from a previous block and not the one right above! The committed fix is to translate PHI assignments to be performed in parallel, like this: p4, p5 := p8, p4; That should fix this issue. --- include/smack/BoogieAst.h | 1 + lib/smack/BoogieAst.cpp | 4 ++++ lib/smack/SmackInstGenerator.cpp | 9 +++++++-- 3 files changed, 12 insertions(+), 2 deletions(-) diff --git a/include/smack/BoogieAst.h b/include/smack/BoogieAst.h index e6ce71cda..8737241ec 100644 --- a/include/smack/BoogieAst.h +++ b/include/smack/BoogieAst.h @@ -180,6 +180,7 @@ class Stmt { static const Stmt* annot(const Attr* a);

Adjusted makefiles and the main build script accordingly. Also extended smackgen script to involve a linking step. Now users should be able to include the SMACK header files from multiple files in their projects, and then link with the compiled C files containing definitions.

Moved SMACK definitions, such as memory models, from a header file into a C file in the share/smack/lib folder. Adjusted makefiles, cmake files, and the main build script accordingly. Also extended smackgen script to compile SMACK headers and to link them against the input file. Added an example simple project showing how to work with SMACK when you have multiple project files. Now users should be able to include the SMACK header files from multiple files in their projects, and then link with the compiled C files containing definitions.
