2010-12-04When deciding whether to complain about the type of a boolean condition, useJohn McCall
the type of the expression *after* array/function decay. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120895 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

2010-12-04Introduce CompilerInvocation::setLangDefaults functionPeter Collingbourne
This patch refactors the CompilerInvocation code to introduce a CompilerInvocation::setLangDefaults function, which can set up a LangOptions with the defaults for a given language and language standard. This function is useful for non-command line based Clang clients which need to set up a CompilerInvocation manually for a specific language. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120874 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-03Implement caching for the linkage and visibility calculations ofDouglas Gregor
declarations. The motivation for this patch is that linkage/visibility computations are linear in the number of redeclarations of an entity, and we've run into a case where a single translation unit has > 6500 redeclarations of the same (unused!) external variable. Since each redeclaration involves a linkage check, the resulting quadratic behavior makes Clang slow to a crawl. With this change, a simple test with 512 redeclarations of a variable syntax-checks ~20x faster than before. That said, I hate this change, and will probably end up reverting it in a few hours. Reasons to hate it: - It makes NamedDecl larger, since we don't have enough free bits in Decl to squeeze in the extra information about caching. - There are way too many places where we need to invalidate this cache, because the visibility of a declaration can change due to redeclarations (!). Despite self-hosting and passing the testsuite, I have no confidence that I've found all of places where this cache needs to be invalidated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120808 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
