2010-12-06Rename CXXExprWithTemporaries -> ExprWithCleanups; there's no theoreticalJohn McCall
reason this is limited to C++, and it's certainly not limited to temporaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120996 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. Leave a FIXME for how to solve this problem for agg __blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120992 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-05Fix a bug in the emission of __real/__imag l-values on scalar operands.John McCall
Fix a bug in the emission of complex compound assignment l-values. Introduce a method to emit an expression whose value isn't relevant. Make that method evaluate its operand as an l-value if it is one. Fixes our volatile compliance in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120931 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-04More anonymous struct/union redesign. This one deals with anonymous field ↵Francois Pichet
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

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

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

2010-12-02Enhance the init generation logic to emit a memset followed by a few stores whenChris Lattner
a global is larger than 32 bytes and has fewer than 6 non-zero values in the initializer. Previously we'd turn something like this: char test8(int X) { char str[10000] = "abc"; into a 10K global variable which we then memcpy'd from. Now we generate: %str = alloca [10000 x i8], align 16 %tmp = getelementptr inbounds [10000 x i8]* %str, i64 0, i64 0 call void @llvm.memset.p0i8.i64(i8* %tmp, i8 0, i64 10000, i32 16, i1 false) store i8 97, i8* %tmp, align 16 %0 = getelementptr [10000 x i8]* %str, i64 0, i64 1 store i8 98, i8* %0, align 1 %1 = getelementptr [10000 x i8]* %str, i64 0, i64 2 store i8 99, i8* %1, align 2 Which is much smaller in space and also likely faster.
