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

2010-08-25Expression statements undergo lvalue-to-rvalue conversion in C,John McCall
but not in C++, so don't emit aggregate loads of volatile references in null context in C++. Happens to have been caught by an assertion. We do not get the scalar case right. Volatiles are really broken. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112019 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22When performing value-initialization for a class with a non-trivial,Douglas Gregor
implicitly-defined default constructor, zero-initialize the memory before calling the default constructor. Previously, we would only zero-initialize in the case of a trivial default constructor. Also, simplify the hideous logic that determines when we have a trivial default constructor and, therefore, don't need to emit any call at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111779 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Experiment with using first-class aggregates to represent member functionJohn McCall
pointers. I find the resulting code to be substantially cleaner, and it makes it very easy to use the same APIs for data member pointers (which I have conscientiously avoided here), and it avoids a plethora of potential inefficiencies due to excessive memory copying, but we'll have to see if it actually works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111776 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Introduce a new cast kind for an "lvalue bitcast", which handlesDouglas Gregor
reinterpret_casts (possibly indirectly via C-style/functional casts) on values, e.g., int i; reinterpret_cast<short&>(i); The IR generated for this is essentially the same as for *reinterpret_cast<short*>(&i). Fixes PR6437, PR7593, and PR7344. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108294 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-06Validated by nightly-test runs on x86 and x86-64 darwin, including afterJohn McCall
self-host. Hopefully these results hold up on different platforms. I tried to keep the GNU ObjC runtime happy, but it's hard for me to test. Reimplement how clang generates IR for exceptions. Instead of creating new invoke destinations which sequentially chain to the previous destination, push a more semantic representation of *why* we need the cleanup/catch/filter behavior, then collect that information into a single landing pad upon request. Also reorganizes how normal cleanups (i.e. cleanups triggered by non-exceptional control flow) are generated, since it's actually fairly closely tied in with the former. Remove the need to track which cleanup scope a block is associated with. Document a lot of previously poorly-understood (by me, at least) behavior. The new framework implements the Horrible Hack (tm), which requires every landing pad to have a catch-all so that inlining will work. Clang no longer requires the Horrible Hack just to make exceptions flow correctly within a function, however. The HH is an unfortunate requirement of LLVM's EH IR. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107631 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."

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

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++.
