From 92ae16b0ae05dd1128d5492faaac9cdb15c7476a Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 13 Oct 2009 06:04:29 +0000 Subject: number address-taken labels from 1. This allows 0 to be used as a sentinel for a null pointer. In other words, "&&foo != NULL" will always work out to true. llvm-svn: 83948 --- clang/lib/CodeGen/CodeGenFunction.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'clang/lib/CodeGen') diff --git a/clang/lib/CodeGen/CodeGenFunction.cpp b/clang/lib/CodeGen/CodeGenFunction.cpp index 10c10d9a8a3..2d4dc455f22 100644 --- a/clang/lib/CodeGen/CodeGenFunction.cpp +++ b/clang/lib/CodeGen/CodeGenFunction.cpp @@ -444,7 +444,7 @@ void CodeGenFunction::ErrorUnsupported(const Stmt *S, const char *Type, unsigned CodeGenFunction::GetIDForAddrOfLabel(const LabelStmt *L) { // Use LabelIDs.size() as the new ID if one hasn't been assigned. - return LabelIDs.insert(std::make_pair(L, LabelIDs.size())).first->second; + return LabelIDs.insert(std::make_pair(L, LabelIDs.size()+1)).first->second; } void CodeGenFunction::EmitMemSetToZero(llvm::Value *DestPtr, QualType Ty) { -- cgit v1.2.3
