2010-07-08Reinstate the fix for PR7556. A silly use of isTrivial() wasDouglas Gregor
suppressing copies of objects with trivial copy constructors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107857 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-08fix the clang side of PR7437: EmitAggregateCopyChris Lattner
was not producing a memcpy with the right address spaces because of two places in it doing casts of the arguments to i8, one of which that didn't preserve the address space. There is also an optimizer bug here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107842 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

2010-06-15Patch adds support for copying of thoseFariborz Jahanian

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
2010-05-22Re-teach IR gen to perform GC moves on rvalues resulting from various ObjCJohn McCall

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

particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. - This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch.
