git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129269 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

2011-04-11Replace a couple of Builder.CreateICmpEQ with Builder.CreateIsNull. No ↵Anders Carlsson
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
2011-01-29When calling a virtual member function on a base class and the most derived ↵Anders Carlsson
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
2011-01-28More work to support -fapple-kext regarding Fariborz Jahanian
indirect vf calls and addition of extra entry at bottom of vtbls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124507 91177308-0d34-0410-b5e6-96231b3b80d8

Pure motion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124484 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-28Reorganize the value-dominance metaprogram and introduce a specializationJohn McCall
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
2011-01-27Do a proper recursive lookup when deciding whether a class's usualJohn McCall
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

Improve on test case. Per Doug's comment. wip. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123954 91177308-0d34-0410-b5e6-96231b3b80d8

counterparts where char units are needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123805 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

2010-12-07PR5207: Change APInt methods trunc(), sext(), zext(), sextOrTrunc() andJay Foad

2010-09-30Introduce -flimit-debug-info.Devang Patel
In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115188 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-27Kill FunctionDecl's IsCopyAssignment bit; it duplicated what couldDouglas Gregor
already be determined by isCopyAssignmentOperator(), and was set too late in the process for all clients to see the appropriate value. Cleanup only; no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114916 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-18Fix a bug with binding l-values to elided temporaries, and leave a coupleJohn McCall
helpful asserts behind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114250 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-17When emitting a new-expression inside a conditional expression,John McCall
the cleanup might not be dominated by the allocation code. In this case, we have to store aside all the delete arguments in case we need them later. There's room for optimization here in cases where we end up not actually needing the cleanup in different branches (or being able to pop it after the initialization code). Also make sure we only call this operator delete along the path where we actually allocated something. Fixes rdar://problem/8439196. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114145 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-15one piece of code is responsible for the lifetime of every aggregateJohn McCall
slot. The easiest way to do that was to bundle up the information we care about for aggregate slots into a new structure which demands that its creators at least consider the question. I could probably be convinced that the ObjC 'needs GC' bit should be rolled into this structure. Implement generalized copy elision. The main obstacle here is that IR-generation must be much more careful about making sure that exactly git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113962 91177308-0d34-0410-b5e6-96231b3b80d8
