2009-11-04Merge constant array and structures. This will create a global variables for ↵Tanya Lattner
arrays and structs that are constant and their initializer is constant. It is on by default but can be disable with the flag -fno-merge-all-constants. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85991 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-04Split out return adjustments in thunks from this adjustment in thunksMike Stump

2009-10-28Implement clang support for indirect branch and address of labelChris Lattner
using the new LLVM support for this. This is temporarily hiding behind horrible and ugly #ifdefs until the time when the optimizer is stable (hopefully a week or so).

2009-10-28Mangle based on the declaration we're given, not the canonicalDouglas Gregor
declaration, since attributes that affect mangling may have been added to subsequent declarations. However, to determine the linkage of the declaration, we need to look at the canonical declaration.

2009-10-27Implement proper linkage for explicit instantiation declarations ofDouglas Gregor
inlined functions. For example, given template<typename T> class string { unsigned Len; public: unsigned size() const { return Len; } }; extern template class string<char>; we now give the instantiation of string<char>::size available_externally linkage (if it is ever instantiated!), as permitted by the C++0x standard. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85340 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27__builtin_object_size refinements. Ensure we handle expressions withMike Stump
side-effects up front, as when we switch to the llvm intrinsic call for __builtin_object_size later, it will have two evaluations. We also finish off the intrinsic version of the code so we can just turn it on once llvm has the intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85324 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-26Prep for future __builtin_object_size refinements. The theory is thatMike Stump
someone will add an llvm intrinsic for us to use, so the optimizer can figure out the hard cases. WIP. For those that want to help, double check with Eric before starting. He has a bit of code this will plug into. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85175 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-23Store the builtin types as CanQualTypes. Expand a bit on the CanQual API,John McCall
but also remove some methods that cause ambiguities, and generally make CanQual<blah> more analogous to QualType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84976 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-23Eliminate QualifiedDeclRefExpr, which captured the notion of aDouglas Gregor
qualified reference to a declaration that is not a non-static data member or non-static member function, e.g., namespace N { int i; } int j = N::i; Instead, extend DeclRefExpr to optionally store the qualifier. Most clients won't see or care about the difference (since QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the number of top-level expression types that clients need to cope with, brings the implementation of DeclRefExpr into line with MemberExpr, and simplifies and unifies our handling of declaration references. Extended DeclRefExpr to (optionally) store explicitly-specified template arguments. This occurs when naming a declaration via a template-id (which will be stored in a TemplateIdRefExpr) that, following template argument deduction and (possibly) overload resolution, is replaced with a DeclRefExpr that refers to a template specialization but maintains the template arguments as written. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84962 91177308-0d34-0410-b5e6-96231b3b80d8
