2009-11-10Minor optimization to skip null check in generated code where it isn'tEli Friedman
necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86741 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-10Fix for PR5454: make sure to use the right block as the predecessor in theEli Friedman

2009-11-09Make sure that Type::getAs<ArrayType>() (or Type::getAs<subclass ofDouglas Gregor
ArrayType>()) does not instantiate. Update all callers that used this unsafe feature to use the appropriate ASTContext::getAs*ArrayType method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86596 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Rearrange function to avoid recursive use-after-free.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86516 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Explicitly note that pre-inc/dec lvalues are not supported yet, so that itEli Friedman
doesn't crash. (Such expressions are valid in C++, but not in C.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86513 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Rename areAllFields32Or64BitBasicType to canExpandIndirectArgument to closer ↵Daniel Dunbar
match what it is semantically used for. Also, fix a major bug where fields from a C++ struct might be dropped -- the expand action doesn't handle them correctly yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86502 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Unify the codepaths used to verify base and member initializers for explicitlyEli Friedman
and implicitly defined constructors. This has a number of benefits: 1. Less code. 2. Explicit and implicit constructors get the same diagnostics. 3. The AST explicitly contains constructor calls from implicit default constructors. This allows handing some cases that previously weren't handled correctly in IRGen without any additional code. Specifically, implicit default constructors containing calls to constructors with default arguments are now handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86500 91177308-0d34-0410-b5e6-96231b3b80d8
