From d25db7ed0f8ec288a770a75b88caaa688ac22079 Mon Sep 17 00:00:00 2001 From: John McCall Date: Mon, 6 May 2013 21:39:12 +0000 Subject: Grab-bag of bit-field fixes: - References to ObjC bit-field ivars are bit-field lvalues; fixes rdar://13794269, which got me started down this. - Introduce Expr::refersToBitField, switch a couple users to it where semantically important, and comment the difference between this and the existing API. - Discourage Expr::getBitField by making it a bit longer and less general-sounding. - Lock down on const_casts of bit-field gl-values until we hear back from the committee as to whether they're allowed. llvm-svn: 181252 --- clang/lib/Sema/SemaChecking.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'clang/lib/Sema/SemaChecking.cpp') diff --git a/clang/lib/Sema/SemaChecking.cpp b/clang/lib/Sema/SemaChecking.cpp index e14635ee25d..a0998a46c66 100644 --- a/clang/lib/Sema/SemaChecking.cpp +++ b/clang/lib/Sema/SemaChecking.cpp @@ -4311,7 +4311,7 @@ static IntRange GetExprRange(ASTContext &C, Expr *E, unsigned MaxWidth) { IntRange::forValueOfType(C, E->getType()); } - if (FieldDecl *BitField = E->getBitField()) + if (FieldDecl *BitField = E->getSourceBitField()) return IntRange(BitField->getBitWidthValue(C), BitField->getType()->isUnsignedIntegerOrEnumerationType()); @@ -4688,7 +4688,7 @@ static void AnalyzeAssignment(Sema &S, BinaryOperator *E) { // We want to recurse on the RHS as normal unless we're assigning to // a bitfield. - if (FieldDecl *Bitfield = E->getLHS()->getBitField()) { + if (FieldDecl *Bitfield = E->getLHS()->getSourceBitField()) { if (AnalyzeBitFieldAssignment(S, Bitfield, E->getRHS(), E->getOperatorLoc())) { // Recurse, ignoring any implicit conversions on the RHS. -- cgit v1.2.3
