2011-05-02Simplify code a bit by using CallArgList::add. No intended functionality ↵Eli Friedman
change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130699 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-01Fully implement delegating constructors!Sean Hunt
As far as I know, this implementation is complete but might be missing a few optimizations. Exceptions and virtual bases are handled correctly. Because I'm an optimist, the web page has appropriately been updated. If I'm wrong, feel free to downgrade its support categories. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130642 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-28Cut down unnecessary zero'ing when value-initializing arrays of C++ objects.Argyrios Kyrtzidis
-C++ objects with user-declared constructor don't need zero'ing. -We can zero-initialize arrays of C++ objects in "bulk" now, in which case don't zero-initialize each object again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130453 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-26Make yet another placeholder type, this one marking that an expression is a ↵John McCall
bound member function, i.e. something of the form 'x.f' where 'f' is a non-static member function. Diagnose this in the general case. Some of the new diagnostics are probably worse than the old ones, but we now get this right much more universally, and there's certainly room for improvement in the diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130239 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129682 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-13Use EmitCallOrInvoke in EmitBadTypeidCall and EmitBadCastCall.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129424 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-11If there's an invoke destination, we should use invoke instead of call when ↵Anders Carlsson
calling the __cxa_bad_typeid function. Fixes PR7400. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129273 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-11When we know that a dynamic_cast always returns null, we can makeAnders Carlsson
CodeGenFunction::EmitDynamicCast always return null or throw a bad_cast exception. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129264 91177308-0d34-0410-b5e6-96231b3b80d8

functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129261 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-10Strip off parens and no-op casts when deciding if an expr can be ↵Anders Carlsson
devirtualized. Fixes the second half of PR9660. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129253 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-09Make sure we or together the overflow flags of the multiply and add, so theEli Friedman
check is triggered appropriately. Reported on cfe-dev. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129231 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-30Remove PHINode::reserveOperandSpace(). Instead, add a parameter toJay Foad
PHINode::Create() giving the (known or expected) number of operands. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128538 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-13Instead of storing an ASTContext* in FunctionProtoTypes with computed ↵Sebastian Redl
noexcept specifiers, unique FunctionProtoTypes with a ContextualFoldingSet, as suggested by John McCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127568 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-12Propagate the new exception information to FunctionProtoType.Sebastian Redl
Change the interface to expose the new information and deal with the enormous fallout. Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications. Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127537 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-11Use a slightly more semantic interface for emitting call arguments.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127494 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07The conditional needs to be pushed before the branch. Make the test lessJohn McCall
trivial to check this. Adjust for style. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127151 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-07An operator new with an empty exception specifier returns null on a badJohn McCall
allocation and therefore requires a null-check. We were doing that, but we weren't treating the new-initializer as being conditionally executed, which means it was possible to get ill-formed IR as in PR9298. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127147 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-08Reorganize CodeGen{Function,Module} to eliminate the unfortunateJohn McCall
Block{Function,Module} base class. Minor other refactorings. Fixed a few address-space bugs while I was there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125085 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-29When trying to get the most derived class, don't assume that we can ignore ↵Anders Carlsson
all casts. We can only ignore derived-to-base and no-op casts. Fixes selfhost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124528 91177308-0d34-0410-b5e6-96231b3b80d8

class is marked 'final', we can devirtualize the call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124524 91177308-0d34-0410-b5e6-96231b3b80d8

for CodeGen's RValue type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124483 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-28Convert the exception-freeing cleanup over to the conditional cleanups code,John McCall
fixing a crash which probably nobody was ever going to see. In doing so, fix a horrendous number of problems with the conditional-cleanups code. Also, make conditional cleanups re-use the cleanup's activation variable, which avoids some unfortunate repetitiveness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124481 91177308-0d34-0410-b5e6-96231b3b80d8

deallocation function has a two-argument form. Store the result of this check in new[] and delete[] nodes. Fixes rdar://problem/8913519 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124373 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-18Add support for explicit constructor calls in Microsoft mode.Francois Pichet
For example: class A{ public: A& operator=(const A& that) { if (this != &that) { this->A::~A(); this->A::A(that); // <=== explicit constructor call. } return *this; } }; More work will be needed to support an explicit call to a template constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123735 91177308-0d34-0410-b5e6-96231b3b80d8
