2011-07-06Properly implement the scope restriction on the NRVO forDouglas Gregor
throw-expressions, such that we don't consider the NRVO when the non-volatile automatic object comes from outside the innermost try scope (C++0x [class.copymove]p13). In C++98/03, our ASTs were incorrect but it didn't matter because IR generation doesn't actually apply the NRVO here. In C++0x, however, we were moving from an object when in fact we should have copied from it.

2011-07-06Build up statistics about the work done for analysis based warnings.Chandler Carruth
Special detail is added for uninitialized variable analysis as this has serious performance problems than need to be tracked. Computing some of this data is expensive, for example walking the CFG to determine its size. To avoid doing that unless the stats data is going to be used, we thread a bit into the Sema object to track whether detailed stats should be collected or not. This bit is used to avoid computations whereever the computations are likely to be more expensive than checking the state of the flag. Thus, counters are in some cases unconditionally updated, but the more expensive (and less frequent) aggregation steps are skipped. With this patch, we're able to see that for 'gcc.c': *** Analysis Based Warnings Stats: 232 functions analyzed (0 w/o CFGs). 7151 CFG blocks built. 30 average CFG blocks per function. 1167 max CFG blocks per function. 163 functions analyzed for uninitialiazed variables 640 variables analyzed. 3 average variables per function. 94 max variables per function. 96409 block visits. 591 average block visits per function. 61546 max block visits per function. And for the reduced testcase in PR10183: *** Analysis Based Warnings Stats: 98 functions analyzed (0 w/o CFGs). 8526 CFG blocks built. 87 average CFG blocks per function. 7277 max CFG blocks per function. 68 functions analyzed for uninitialiazed variables 1359 variables analyzed. 19 average variables per function. 1196 max variables per function. 2540494 block visits. 37360 average block visits per function. 2536495 max block visits per function.

2011-07-01Fix AST representations of alias-declarations which define tag types. Inside ↵Richard Smith
classes, the tag types need to have an associated access specifier, and inside function definitions, they need to be included in the declarations of the DeclStmt.

2011-07-01Introduce the notion of instantiation dependence into Clang's AST. ADouglas Gregor
type/expression/template argument/etc. is instantiation-dependent if it somehow involves a template parameter, even if it doesn't meet the requirements for the more common kinds of dependence (dependent type, type-dependent expression, value-dependent expression). When we see an instantiation-dependent type, we know we always need to perform substitution into that instantiation-dependent type. This keeps us from short-circuiting evaluation in places where we shouldn't, and lets us properly implement C++0x [temp.type]p2. In theory, this would also allow us to properly mangle instantiation-dependent-but-not-dependent decltype types per the Itanium C++ ABI, but we aren't quite there because we still mangle based on the canonical type in cases like, e.g., template<unsigned> struct A { }; template<typename T> void f(A<sizeof(sizeof(decltype(T() + T())))>) { } template void f<int>(A<sizeof(sizeof(int))>); and therefore get the wrong answer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134225 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-18Accept no-return stripping conversions for pointer type arguments afterChandler Carruth
deducing template parameter types. Recently Clang began enforcing the more strict checking that the argument type and the deduced function parameter type (after substitution) match, but that only consideres qualification conversions. One problem with this patch is that we check noreturn conversions and qualification conversions independently. If a valid conversion would require *both*, perhaps interleaved with each other, it will be rejected. If this actually occurs (I'm not yet sure it does) and is in fact a problem (I'm not yet sure it is), there is a FIXME to implement more intelligent conversion checking. However, this step at least allows Clang to resume accepting valid code we're seeing in the wild. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133327 91177308-0d34-0410-b5e6-96231b3b80d8
