From 867c8db5cc6bf062c1324213656ddf1d7ddb5ad9 Mon Sep 17 00:00:00 2001 From: Simon Pilgrim Date: Wed, 16 Oct 2019 10:38:49 +0000 Subject: CGDebugInfo - silence static analyzer dyn_cast<> null dereference warnings. NFCI. The static analyzer is warning about potential null dereferences, but in these cases we should be able to use cast<> directly and if not assert will fire for us. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@374989 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CGDebugInfo.cpp | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/lib/CodeGen/CGDebugInfo.cpp b/lib/CodeGen/CGDebugInfo.cpp index c6662e5f8b..3d140ba7d7 100644 --- a/lib/CodeGen/CGDebugInfo.cpp +++ b/lib/CodeGen/CGDebugInfo.cpp @@ -1791,6 +1791,7 @@ CGDebugInfo::CollectTemplateParams(const TemplateParameterList *TPList, CGM.getContext().toCharUnitsFromBits((int64_t)fieldOffset); V = CGM.getCXXABI().EmitMemberDataPointer(MPT, chars); } + assert(V && "Failed to find template parameter pointer"); V = V->stripPointerCasts(); } TemplateParams.push_back(DBuilder.createTemplateValueParameter( @@ -3327,13 +3328,13 @@ llvm::DISubprogram *CGDebugInfo::getFunctionFwdDeclOrStub(GlobalDecl GD, unsigned Line = getLineNumber(Loc); collectFunctionDeclProps(GD, Unit, Name, LinkageName, DContext, TParamsArray, Flags); - auto *FD = dyn_cast(GD.getDecl()); + auto *FD = cast(GD.getDecl()); // Build function type.
