From f1bd2e48c5324d3f7cda4090c87f8a5b6f463ce2 Mon Sep 17 00:00:00 2001 From: "Zancanaro; Carlo" Date: Mon, 15 Oct 2012 17:08:15 +1100 Subject: Fix up the Equation System generation. Now there's a bug in the solver. The solver seems to work fine when run as a tool by itself, but not in the clang stuff. Very annoying. --- .../Core/IntervalConstraintManager.cpp | 27 +++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) (limited to 'clang/lib/StaticAnalyzer/Core') diff --git a/clang/lib/StaticAnalyzer/Core/IntervalConstraintManager.cpp b/clang/lib/StaticAnalyzer/Core/IntervalConstraintManager.cpp index 9d04720..dc2f0d9 100644 --- a/clang/lib/StaticAnalyzer/Core/IntervalConstraintManager.cpp +++ b/clang/lib/StaticAnalyzer/Core/IntervalConstraintManager.cpp @@ -254,6 +254,7 @@ private: ConstraintManager* ento::CreateIntervalConstraintManager(ProgramStateManager&, SubEngine &subeng) { + llvm::errs() << "Creating interval constraint manager\n"; return new IntervalConstraintManager(subeng); } @@ -294,7 +295,7 @@ IntervalConstraintManager::GetRange(ProgramStateRef state, SymbolRef sym) { } //===------------------------------------------------------------------------=== -// assumeSymX methods: public interface for IntervalConstraintManager. +// eSymX methods: public interface for IntervalConstraintManager. //===------------------------------------------------------------------------===/ // The syntax for ranges below is mathematical, using [x, y] for closed ranges @@ -309,6 +310,10 @@ ProgramStateRef IntervalConstraintManager::assumeSymNE(ProgramStateRef state, SymbolRef sym, const llvm::APSInt& Int, const llvm::APSInt& Adjustment) { + llvm::errs() << "AssumeNE\n"; + state->dump(); + sym->dump(); + BasicValueFactory &BV = state->getBasicVals(); llvm::APSInt Lower = Int-Adjustment; @@ -326,6 +331,10 @@ ProgramStateRef IntervalConstraintManager::assumeSymEQ(ProgramStateRef state, SymbolRef sym, const llvm::APSInt& Int, const llvm::APSInt& Adjustment) { + llvm::errs() << "AssumeEQ\n"; + state->dump(); + sym->dump(); + // [Int-Adjustment, Int-Adjustment] BasicValueFactory &BV = state->getBasicVals(); llvm::APSInt AdjInt = Int-Adjustment; @@ -337,6 +346,10 @@ ProgramStateRef IntervalConstraintManager::assumeSymLT(ProgramStateRef state, SymbolRef sym, const llvm::APSInt& Int, const llvm::APSInt& Adjustment) { + llvm::errs() << "AssumeLT\n"; + state->dump(); + sym->dump(); + BasicValueFactory &BV = state->getBasicVals(); QualType T = state->getSymbolManager().getType(sym); @@ -358,6 +371,10 @@ ProgramStateRef IntervalConstraintManager::assumeSymGT(ProgramStateRef state, SymbolRef sym, const llvm::APSInt& Int, const llvm::APSInt& Adjustment) { + llvm::errs() << "AssumeGT\n"; + state->dump(); + sym->dump(); + BasicValueFactory &BV = state->getBasicVals(); QualType T = state->getSymbolManager().getType(sym); @@ -379,6 +396,10 @@ ProgramStateRef IntervalConstraintManager::assumeSymGE(ProgramStateRef state, SymbolRef sym, const llvm::APSInt& Int, const llvm::APSInt& Adjustment) { + llvm::errs() << "AssumeGE\n"; + state->dump(); + sym->dump(); + BasicValueFactory &BV = state->getBasicVals(); QualType T = state->getSymbolManager().getType(sym); @@ -401,6 +422,10 @@ ProgramStateRef IntervalConstraintManager::assumeSymLE(ProgramStateRef state, SymbolRef sym, const llvm::APSInt& Int, const llvm::APSInt& Adjustment) { + llvm::errs() << "AssumeLE\n"; + state->dump(); + sym->dump(); + BasicValueFactory &BV = state->getBasicVals(); QualType T = state->getSymbolManager().getType(sym); -- cgit v1.2.3
