From 3ae0a79c0d066a57b3755a2634c8cbd5d1c8fdf2 Mon Sep 17 00:00:00 2001 From: Anna Thomas Date: Thu, 23 Mar 2017 20:00:54 +0000 Subject: [PATCH] [LVIPrinterPass] Print LVI info for function arguments Using AssemblyAnnotationWriter for LVI printer prints for instructions and basic blocks. So, we explicitly need to print LVI info for the arguments of the function (these are values and not instructions). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@298640 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/LazyValueInfo.cpp | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/lib/Analysis/LazyValueInfo.cpp b/lib/Analysis/LazyValueInfo.cpp index 05820529363..17e781375e4 100644 --- a/lib/Analysis/LazyValueInfo.cpp +++ b/lib/Analysis/LazyValueInfo.cpp @@ -486,6 +486,18 @@ namespace { OS << "; OverDefined values for block are: \n"; for (auto *V : ODI->second) OS << ";" << *V << "\n"; + + // Find if there are latticevalues defined for arguments of the function. + auto *F = const_cast(BB->getParent()); + for (auto &Arg : F->args()) { + auto VI = LVICache->ValueCache.find_as(&Arg); + if (VI == LVICache->ValueCache.end()) + continue; + auto BBI = VI->second->BlockVals.find(const_cast(BB)); + if (BBI != VI->second->BlockVals.end()) + OS << "; CachedLatticeValue for: '" << *VI->first << "' is: '" + << BBI->second << "'\n"; + } } virtual void emitInstructionAnnot(const Instruction *I, -- 2.50.1
