2009-05-21Template instantiation for C99 designated initializers, because weDouglas Gregor
can. Also, delay semantic analysis of initialization for value-dependent as well as type-dependent expressions, since we can't always properly type-check a value-dependent expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72233 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-16PR3009: Get rid of bogus warning for scalar compound literals.Eli Friedman
This patch isn't quite ideal in that it eliminates the warning for constructs like "int a = {1};", where the braces are in fact redundant. However, that would have required a bunch of refactoring, and it's much less likely to cause confusion compared to redundant nested braces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71939 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-25fix PR4073 by making designated initializer checking code useChris Lattner
VerifyIntegerConstantExpression instead of isIntegerConstantExpr. This makes it ext-warn but tolerate things that fold to a constant but that are not valid i-c-e's. There must be a bug in the i-c-e computation though, because it doesn't catch this case even with pedantic. This also switches the later code to use EvaluateAsInt which is simpler and handles everything that evaluate does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70081 91177308-0d34-0410-b5e6-96231b3b80d8

syntax into extension warnings, and provide code-modification hints showing how to fix the problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67885 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-21Fix a thinko in the pre-allocation strategy for structured initializerDouglas Gregor
lists. The code wasn't accounting for the distinction between the top-level call to getStructuredSubobjectInit and later calls that occur deeper in the hierarchy. This problem manifested itself as over-allocation in cases where we have large arrays of small structures (<rdar://problem/6707362>). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67452 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-20When building the structured initializer list, pre-allocate storage inDouglas Gregor
its vectors based on the subobject type we're initializing and the (unstructured) initializer list. This eliminates some malloc thrashing when parsing initializers (from 117 vector reallocations down to 0 when parsing Cocoa.h). We can't always pre-allocate the right amount of storage, since designated initializers can cause us to initialize in non-predictable patterns. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67421 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-20Allow flexible array initializers that are not surrounded byDouglas Gregor
braces. We now build the appropriate fully-structured initializer list for such things. Per PR3618, verified that we're getting the right code generation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67353 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26ok, not as broken as I thought, just confusing. This allows Chris Lattner
initialization of wchar_t arrays with wide strings, and generalizes wchar_size.c to work on all targets. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65586 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18Downgrade the "excess elements in initializer" errors to warnings *inDouglas Gregor
C*. They're required errors in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64964 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12Fix a bug with designated initializers where we were stepping out of aDouglas Gregor
union subobject initialization before checking whether the next initiailizer was actually a designated initializer. This led to spurious "excess elements in union initializer" errors. Thanks to rdivacky for reporting the bug! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64392 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-09When handling "the rest" of a designated array subobject, maybe sureDouglas Gregor
to tell it that it wasn't (directly) designated. This way, we unwind back to the explicit initializer list properly rather than getting stuck in the wrong subobject. Fixes llvm.org/PR3519 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64155 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04Implement semantic analysis for the GNU flexible array initializationDouglas Gregor
extension. The interaction with designated initializers is a bit... interesting... but we follow GNU's lead and don't permit too much crazy code in this area. Also, make the "excess initializers" error message a bit more informative. Addresses PR2561: http://llvm.org/bugs/show_bug.cgi?id=2561 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63785 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-30Upgrade the "excess elements in array initializer" warning to anDouglas Gregor
error, since both C99 and C++ consider it an error. For reference, GCC makes this a warning while G++ makes it an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63435 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30Implement and test aggregate initialization in C++. Major changes:Douglas Gregor
- Support initialization of reference members; complain if any reference members are left uninitialized. - Use C++ copy-initialization for initializing each element (falls back to constraint checking in C) - Make sure we diagnose when one tries to provide an initializer list for a non-aggregate. - Don't complain about empty initializers in C++ (they are permitted) - Unrelated but necessary: don't bother trying to convert the decl-specifier-seq to a type when we're dealing with a C++ constructor, destructor, or conversion operator; it results in spurious warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63431 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30Switch Type::isAggregateType to use the C++ definition of "aggregateDouglas Gregor
type" rather than the C definition. We do this because both C99 and Clang always use "aggregate type" as "aggregate or union type", and the C++ definition includes union types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63395 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29Introduce a new expression node, ImplicitValueInitExpr, thatDouglas Gregor
represents an implicit value-initialization of a subobject of a particular type. This replaces the (ab)use of CXXZeroValueInitExpr within initializer lists for the "holes" that occur due to the use of C99 designated initializers. The new test case is currently XFAIL'd, because CodeGen's ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be taught to value-initialize when it sees ImplicitValueInitExprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63317 91177308-0d34-0410-b5e6-96231b3b80d8
