2012-02-26A follow-up to r151482 which added support for powerpc and powerpc64Chandler Carruth
Debian multiarch libraries, this should in theory add support for those platform's header search rules. I don't have a system to check this with, so review appreciated. I've added the corresponding tests referring to the debian multiarch tree. We are starting to have a relatively completely tested Linux platform for header search and library search, with several interesting peculiarities. We should point people at the debian_multiarch_tree when suggesting new tests. Folks with Debian systems that can check this for correctness, it would be much appreciated. The missing chunks I know of are testing bi-arch peudo-cross-compiling toolchains betwen 32-bit and 64-bit variants of platforms, and the MIPS and ARM Debian toolchains. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151484 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-26Ensure that we delete destructors in the right cases. Specifically:Richard Smith
- variant members with nontrivial destructors make the containing class's destructor deleted - check for a virtual destructor after checking for overridden methods in the base class(es) - check for an inaccessible operator delete for a class with a virtual destructor. Do not try to call an anonymous union field's destructor from the destructor of the containing class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151483 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-26Add support for PPC and PPC64 multiarch toolchains on Debain.Chandler Carruth
Patch from Michel Dänzer, sent our way via Jeremy Huddleston who added 64-bit support. I just added one other place where powerpc64-linux-gnu was missing (we only had powerpc64-unknown-linux-gnu). I've also added a tree to test out the debian multiarch stuff. I don't use debian regularly, so I'm not certain this is entirely accurate. If anyone wants to check it against a debian system and fix any inaccuracies, fire away. This way at least folks can see how this is *supposed* to be tested. It'd be particularly good to get the Debian MIPS toolchains tested in this way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151482 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-26Special members which are defaulted or deleted on their first declaration areRichard Smith
trivial if the implicit declaration would be. Don't forget to set the Trivial flag on the special member as well as on the class. It doesn't seem ideal that we have two separate mechanisms for storing this information, but this patch does not attempt to address that. This leaves us in an interesting position where the has_trivial_X trait for a class says 'yes' for a deleted but trivial X, but is_trivially_Xable says 'no'. This seems to be what the standard requires. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151465 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-25CodeGen support for global variables of type std::initializer_list<X>.Sebastian Redl
This emits a backing array with internal linkage and fills it with data, then has the initializer_list point at the array. Dynamic initialization and global destructors are correctly supported. What doesn't work is nested initializer_lists. I have no idea how to get them to work, either. However, these should be very rare, and so I'll just call it a known bug and declare generalized initializers DONE! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151457 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24[analyzer] Malloc: reason about the ObjC messages and C++.Anna Zaks
Assume none of the ObjC messages defined in system headers free memory, except for the ones containing 'freeWhenDone' selector. Currently, just assume that the region escapes to the messages with 'freeWhenDone' (ideally, we want to treat it as 'free()'). For now, always assume that regions escape when passed to C++ methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151410 91177308-0d34-0410-b5e6-96231b3b80d8
