* Implementing C99 partial re-initialization behavior (DR-253)Yunzhong Gao2015-06-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Based on previous discussion on the mailing list, clang currently lacks support for C99 partial re-initialization behavior: Reference: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-April/029188.html Reference: http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_253.htm This patch attempts to fix this problem. Given the following code snippet, struct P1 { char x[6]; }; struct LP1 { struct P1 p1; }; struct LP1 l = { .p1 = { "foo" }, .p1.x[2] = 'x' }; // this example is adapted from the example for "struct fred x[]" in DR-253; // currently clang produces in l: { "\0\0x" }, // whereas gcc 4.8 produces { "fox" }; // with this fix, clang will also produce: { "fox" }; Differential Review: http://reviews.llvm.org/D5789 llvm-svn: 239446
* Rename MacroDefinition -> MacroDefinitionRecord, ↵Richard Smith2015-05-041-17/+15
| | | | | | | | | | Preprocessor::MacroDefinition -> MacroDefinition. clang::MacroDefinition now models the currently-defined value of a macro. The previous MacroDefinition type, which represented a record of a macro definition directive for a detailed preprocessing record, is now called MacroDefinitionRecord. llvm-svn: 236400

* [c++1z] N4295: fold-expressions.Richard Smith2014-11-081-0/+1
| | | | | | | | | | | | | | | | This is a new form of expression of the form: (expr op ... op expr) where one of the exprs is a parameter pack. It expands into (expr1 op (expr2onwards op ... op expr)) (and likewise if the pack is on the right). The non-pack operand can be omitted; in that case, an empty pack gives a fallback value or an error, depending on the operator. llvm-svn: 221573

* Add the intrinsic __builtin_convertvectorHal Finkel2013-09-181-0/+1
| | | | | | | | | | | | | | | | | | LLVM supports applying conversion instructions to vectors of the same number of elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to cause such instructions to be generated when using builtin vector types. C-style casting on vectors is already defined in terms of bitcasts, and so cannot be used for these conversions as well (without leading to a very confusing set of semantics). As a result, this adds a __builtin_convertvector intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is intended to aid the creation of vector intrinsic headers that create generic IR instead of target-dependent intrinsics (in other words, this is a generic _mm_cvtepi32_ps). As noted in the documentation, the action of __builtin_convertvector is defined in terms of the action of a C-style cast on each vector element. llvm-svn: 190915
* Remove unnecessary inclusion of Sema.hDavid Blaikie2013-09-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let me tell you a tale... Within some twisted maze of debug info I've ended up implementing an insane man's Include What You Use device. When the debugger emits debug info it really shouldn't, I find out why & then realize the code could be improved too. In this instance CIndexDiagnostics.cpp had a lot more debug info with Clang than GCC. Upon inspection a major culprit was all the debug info describing clang::Sema. This was emitted because clang::Sema is befriended by DiagnosticEngine which was rightly required, but GCC doesn't emit debug info for friends so it never emitted anything for Clang. Clang does emit debug info for friends (will be fixed/changed to reduce debug info size). But why didn't Clang just emit a declaration of Sema if this entire TU didn't require a definition? 1) Diagnostic.h did the right thing, only using a declaration of Sema and not including Sema.h at all. 2) Some other dependency of CIndexDiagnostics.cpp didn't do the right thing. ASTUnit.h, only needing a declaration, still included Sema.h (hence this commit which removes that include and adds the necessary includes to the cpp files that were relying on this) 3) -flimit-debug-info didn't save us because of EnterExpressionEvaluationContext, defined inline in Sema.h which fires the "requiresCompleteType" check/flag (since it uses nested types from Sema and calls Sema member functions) and thus, if debug info is ever emitted for the type, the whole type is emitted and not just a declaration. Improving -flimit-debug-info to account for this would be... hard. Modifying the code so that's not 'required to be complete' might be possible, but probably only by moving EnterExpressionEvaluationContext either into Sema, or out of Sema.h. That might be a bit too much of a contortion to be bothered with. Also, this is only one of the cases where emitting debug info for friends caused us to emit a lot more debug info (this change reduces Clang's DWO size by 0.93%, dropping friends entirely reduces debug info by 3.2%) - I haven't hunted down the other cases, but I assume they might be similar (Sema or something like it). IWYU or a similar tool might help us reduce build times a bit, but analyzing debug info to find these differences isn't worthwhile. I'll take the 3.2% win, provide this small improvement to the code itself, and move on. llvm-svn: 190715

* PR12086, PR15117Richard Smith2013-06-121-0/+1
| | | | | | | | | | | | | | | | | | | Introduce CXXStdInitializerListExpr node, representing the implicit construction of a std::initializer_list<T> object from its underlying array. The AST representation of such an expression goes from an InitListExpr with a flag set, to a CXXStdInitializerListExpr containing a MaterializeTemporaryExpr containing an InitListExpr (possibly wrapped in a CXXBindTemporaryExpr). This more detailed representation has several advantages, the most important of which is that the new MaterializeTemporaryExpr allows us to directly model lifetime extension of the underlying temporary array. Using that, this patch *drastically* simplifies the IR generation of this construct, provides IR generation support for nested global initializer_list objects, fixes several bugs where the destructors for the underlying array would accidentally not get invoked, and provides constant expression evaluation support for std::initializer_list objects. llvm-svn: 183872

| | | | | | | | | | | Add a CXXDefaultInitExpr, analogous to CXXDefaultArgExpr, and use it both in CXXCtorInitializers and in InitListExprs to represent a default initializer. There's an additional complication here: because the default initializer can refer to the initialized object via its 'this' pointer, we need to make sure that 'this' points to the right thing within the evaluation. llvm-svn: 179958
