The macros required for DeclNodes use have changed to match the use of StmtNodes. The FooFirst enumerator constants have been named firstFoo to match usage elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105165 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-30Fix for PR7040: Don't try to compute the LLVM type for a function where itEli Friedman
isn't possible to compute. This patch is mostly refactoring; the key change is the addition of the code starting with the comment, "Check whether the function has a computable LLVM signature." The solution here is essentially the same as the way the vtable code handles such functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105151 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-25Improve name mangling for blocks and support mangling of static localDouglas Gregor
variables within blocks. We loosely follow GCC's mangling, but since these are always internal symbols the names don't really matter. I intend to revisit block mangling later, because GCC's mangling is rather verbose. <rdar://problem/8015719>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104610 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-25If a function definition has any sort of weak linkage, its static localJohn McCall
variables should have that linkage. Otherwise, its static local variables should have internal linkage. To avoid computing this excessively, set a function's linkage before we emit code for it. Previously we were assigning weak linkage to the static variables of static inline functions in C++, with predictably terrible results. This fixes that and also gives better linkage than 'weak' when merging is required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104581 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-22Improve our handling of reference binding for subobjects ofDouglas Gregor
temporaries. There are actually several interrelated fixes here: - When converting an object to a base class, it's only an lvalue cast when the original object was an lvalue and we aren't casting pointer-to-derived to pointer-to-base. Previously, we were misclassifying derived-to-base casts of class rvalues as lvalues, causing various oddities (including problems with reference binding not extending the lifetimes of some temporaries). - Teach the code for emitting a reference binding how to look through no-op casts and parentheses directly, since Expr::IgnoreParenNoOpCasts is just plain wrong for this. Also, make sure that we properly look through multiple levels of indirection from the temporary object, but destroy the actual temporary object; this fixes the reference-binding issue mentioned above. - Teach Objective-C message sends to bind the result as a temporary when needed. This is actually John's change, but it triggered the reference-binding problem above, so it's included here. Now John can actually test his return-slot improvements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104434 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-20Assert that we do not try to memcpy a non-POD class type in C++. ThisDouglas Gregor
particular issue was the cause of the Boost.Interprocess failures, and in general will lead to horrendous, hard-to-diagnose miscompiles. The assertion itself has survives self-host and a full Boost build, so we are close to eradicating this problem in C++. Note that the assertion is *not* turned on for Objective-C++, where we still have problems with introducing memcpy's of non-POD class types. That part of the assertion will go away as soon as we fix the known issues in Objective-C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104227 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-20Rework our handling of binding a reference to a temporaryDouglas Gregor
subobject. Previously, we could only properly bind to a base class subobject while extending the lifetime of the complete object (of a derived type); for non-static data member subobjects, we could memcpy (!) the result and bind to that, which is rather broken. Now, we pull apart the expression that we're binding to, to figure out which subobject we're accessing, then construct the temporary object (adding a destruction if needed) and, finally, dig out the subobject we actually meant to access. This fixes yet another instance where we were memcpy'ing rather than doing the right thing. However, note the FIXME in references.cpp: there's more work to be done for binding to subobjects, since the AST is incorrectly modeling some member accesses in base classes as lvalues when they are really rvalues. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104219 91177308-0d34-0410-b5e6-96231b3b80d8
