2010-12-17Give hidden visibility to RTTI for derived types. This is kindof a hackyJohn McCall
way to do this, but it fixes rdar://problem/8778973 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122033 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-15Implement builtins for Neon half-precision float conversions.Bob Wilson

2010-12-15Set the "implicitly inline" bit on a method as soon as we see a definitionJohn McCall

2010-12-14Factor out most of the extra state in a FunctionProtoType into a separateJohn McCall
class to be passed around. The line between argument and return types and everything else is kindof vague, but I think it's justifiable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121752 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10It's kindof silly that ExtQuals has an ASTContext&, and we can use thatJohn McCall
space better. Remove this reference. To make that work, change some APIs (most importantly, getDesugaredType()) to take an ASTContext& if they need to return a QualType. Simultaneously, diminish the need to return a QualType by introducing some useful APIs on SplitQualType, which is just a std::pair<const Type *, Qualifiers>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121478 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-06__block variables require us to evaluate the RHS of an assignment beforeJohn McCall
the LHS, or else the pointer might be invalid. This is kindof dumb, but go ahead and make sure we're doing that for l-value scalar assignment, which fixes a miscompile of obj-c++.dg/block-seq.mm.

Fix a bug in the emission of complex compound assignment l-values. Introduce a method to emit an expression whose value isn't relevant.

used in a constructor initializer list: struct X { X() : au_i1(123) {} union { int au_i1; float au_f1; }; }; clang will now deal with au_i1 explicitly as an IndirectFieldDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120900 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Remove some defensive calls to EmitLoadOfPropertyRefLValue that shouldn'tJohn McCall
be required, and then fix up some missing loads on overloaded-operator paths which that exposed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120896 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Although we currently have explicit lvalue-to-rvalue conversions, they'reJohn McCall
not actually frequently used, because ImpCastExprToType only creates a node if the types differ. So explicitly create an ICE in the lvalue-to-rvalue conversion code in DefaultFunctionArrayLvalueConversion() as well as several other new places, and consistently deal with the consequences throughout the compiler. In addition, introduce a new cast kind for loading an ObjCProperty l-value, and make sure we emit those nodes whenever an ObjCProperty l-value appears that's not on the LHS of an assignment operator. This breaks a couple of rewriter tests, which I've x-failed until future development occurs on the rewriter. Ted Kremenek kindly contributed the analyzer workarounds in this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120890 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Test case for the l-value base only being evaluated once.John McCall
Also, move the l-value emission code into CGObjC.cpp and teach it, for completeness, to store away self for a super send.

2010-12-02Improve codegen for initializer lists to use memset more aggressivelyChris Lattner
when an initializer is variable (I handled the constant case in a previous patch). This has three pieces: 1. Enhance AggValueSlot to have a 'isZeroed' bit to tell CGExprAgg that the memory being stored into has previously been memset to zero. 2. Teach CGExprAgg to not emit stores of zero to isZeroed memory. 3. Teach CodeGenFunction::EmitAggExpr to scan initializers to determine whether they are profitable to emit a memset + inividual stores vs stores for everything. The heuristic used is that a global has to be more than 16 bytes and has to be 3/4 zero to be candidate for this xform. The two testcases are illustrative of the scenarios this catches. We now codegen test9 into: call void @llvm.memset.p0i8.i64(i8* %0, i8 0, i64 400, i32 4, i1 false) %.array = getelementptr inbounds [100 x i32]* %Arr, i32 0, i32 0 %tmp = load i32* %X.addr, align 4 store i32 %tmp, i32* %.array and test10 into: call void @llvm.memset.p0i8.i64(i8* %0, i8 0, i64 392, i32 8, i1 false) %tmp = getelementptr inbounds %struct.b* %S, i32 0, i32 0 %tmp1 = getelementptr inbounds %struct.a* %tmp, i32 0, i32 0 %tmp2 = load i32* %X.addr, align 4 store i32 %tmp2, i32* %tmp1, align 4 %tmp5 = getelementptr inbounds %struct.b* %S, i32 0, i32 3 %tmp10 = getelementptr inbounds %struct.a* %tmp5, i32 0, i32 4 %tmp11 = load i32* %X.addr, align 4 store i32 %tmp11, i32* %tmp10, align 4 Previously we produced 99 stores of zero for test9 and also tons for test10. This xforms should substantially speed up -O0 builds when it kicks in as well as reducing code size and optimizer heartburn on insane cases. This resolves PR279. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120692 91177308-0d34-0410-b5e6-96231b3b80d8
