* Fix for PR7040: Don't try to compute the LLVM type for a function where itEli Friedman2010-05-301-25/+1
| | | | | | | | | | | 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. llvm-svn: 105151
* Re-teach IR gen to perform GC moves on rvalues resulting from various ObjCJohn McCall2010-05-221-17/+54

* Improve our handling of reference binding for subobjects ofDouglas Gregor2010-05-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 104434

| | | | | | | | | | | | | | 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++. llvm-svn: 104227
