2010-12-02Do not change the size of LookupResult::Filter based on the NDEBUGDouglas Gregor
macri; the extra bool fits into padding anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120708 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-02Remove NDEBUG-controlled extra data fromDouglas Gregor
TemplateArgumentLocInfo. Unfortunately, this means that we lose some internal consistency checking when building a debug Clang. However, having data structures change size/layout depending on NDEBUG causes pain for clients of the Clang API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120706 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-02Add a test for calling a Neon intrinsic macro with the wrong vector type.Bob Wilson
This does not work so well with the -fno-lax-vector-conversions option for testing the arm_neon.h header but that is a really useful test, so I split this out to a separate Sema test to check for the warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120694 91177308-0d34-0410-b5e6-96231b3b80d8
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. This is part of PR279 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120645 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-01Extend ExternalASTSource with the ability to lazily complete theDouglas Gregor
definition of an Objective-C class. Unlike with C/C++ classes, we don't have a well-defined point in Sema where Objective-C classes are checked for completeness, nor do we need to involve Sema when completing a class. Therefore, we take the appropriate of having the external AST source mark a particular Objective-C class as having an external declaration; when using one of the accessors of an Objective-C class that has an external declaration, we request that the external AST source fill in the Objective-C class definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120627 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-01Improve our handling of cv-qualifiers in Objective-C pointerDouglas Gregor
conversions. Previously, we would end up collapsing qualification conversions into the Objective-C pointer conversion step, including (possibly) stripping qualifiers that shouldn't be removed. This generalizes BuildSimilarlyQualifiedPointerType() to also work on Objective-C object pointers, then eliminates the (redundant, not totally correct) BuildSimilarlyQualifiedObjCObjectPointerType() function.
