* Add a new GetAddressOfBaseClass overload that takes a base path and. Use it ↵Anders Carlsson2010-04-241-1/+5
| | | | | | for derived-to-base casts. llvm-svn: 102270
* Handle compound assignment expressions (i += j) as lvalues, which isDouglas Gregor2010-04-231-0/+1
| | | | | | | permitted in C++ but not in C. Fixes PR6900. Clang can now handle all of Boost.Lambda's regression tests. llvm-svn: 102170
* Call PerformCopyInitialization to properly initialize the exception temporaryJohn McCall2010-04-221-0/+3
| | | | | | | | | in a throw expression. Use EmitAnyExprToMem to emit the throw expression, which magically elides the final copy-constructor call (which raises a new strict-compliance bug, but baby steps). Give __cxa_throw a destructor pointer if the exception type has a non-trivial destructor. llvm-svn: 102039
* I failed to notice that my last patch wasn't doing as much as it couldJohn McCall2010-04-211-1/+2
| | | | | | | because EmitBranch actually clears the insert point. This version actually accomplishes what I initially wanted. llvm-svn: 101998
* Miscellaneous codegen cleanups. Mostly, don't create new basic blocksJohn McCall2010-04-211-7/+11
| | | | | | | just to save the current insertion state! This change significantly simplifies the IR CFG in exceptions code. llvm-svn: 101996
* Back out r101911 and see if it makes the bots happy.Anders Carlsson2010-04-201-2/+0
| | | | llvm-svn: 101921
* Fix a bug which triggered the assertion I added yesterday. Basically, when ↵Anders Carlsson2010-04-201-0/+2
| | | | | | we initialize the vtable pointer for a virtual base, and there was another path from the most derived class to another base with the same class type, we would use the wrong base. llvm-svn: 101911
* Pass the nearest virtual base decl to InitializeVTablePointers. No ↵Anders Carlsson2010-04-201-4/+4

* Reapply r99775 with a fix for a silly bug - we were setting the vtable ↵Anders Carlsson2010-03-281-4/+6
| | | | | | pointer for all bases, even those without a vtable pointer :) llvm-svn: 99777
* Looks like I broke self-host again :(.Anders Carlsson2010-03-281-6/+4
| | | | llvm-svn: 99776
* More improvements to setting the vtable pointer. We now no longer set the ↵Anders Carlsson2010-03-281-4/+6
| | | | | | vtable pointer for non-virtual primary bases. We also do a pre-order traversal of the class hierarchy; this is necessary in order to get the right vbase offset offsets in base ctors/dtors. llvm-svn: 99775
* Factor vtable pointer setting code out into a separate function.Anders Carlsson2010-03-281-1/+13

* C++: Add support for -fno-use-cxa-atexit.Daniel Dunbar2010-03-201-0/+14

* add framework for ARM builtins, Patch by Edmund Grimley Evans!Chris Lattner2010-03-031-0/+1

* Add proper target hooks for __builtin_extract_return_address andJohn McCall2010-03-031-1/+5
| | | | | | | __builtin_frob_return_address. The implementations for both are still trivial in the default case. llvm-svn: 97638
* Unconditionally support block introspection data in a new field at the endBlaine Garst2010-02-231-1/+2
| | | | | | | | | | | | | | | of the block descriptor field. This field is the ObjC style @encode signature of the implementation function, and was to this point conditionally provided in the block literal data structure. That provisional support is removed. Additionally, eliminate unused enumerations for the block literal flags field. The first shipping ABI unconditionally set (1<<29) but this bit is unused by the runtime, so the second ABI will unconditionally have (1<<30) set so that the runtime can in fact distinguish whether the additional data is present or not. llvm-svn: 96989
* Perform two more constructor/destructor code-size optimizations:John McCall2010-02-231-0/+3
| | | | | | | | | | | | | | | | 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. llvm-svn: 96842
* More refactoring around constructor/destructor code generation.John McCall2010-02-191-16/+13
| | | | | | | | | | | | Fix some bugs with function-try-blocks and simplify normal try-block code generation. This implementation excludes a deleting destructor's call to operator delete() from the function-try-block, which I believe is correct but which I can't find straightforward support for at a moment's glance. llvm-svn: 96670
* Extract out function-body code generation into its own method. No functionalityJohn McCall2010-02-181-9/+5

* IRgen optimization: cache the value of 'this' and 'vtt' instead ofJohn McCall2010-02-161-2/+10
| | | | | | | | repeatedly reloading from an alloca. We still need to create the alloca for debug info purposes (although we currently create it in all cases because of some abstraction boundaries that're hard to break down). llvm-svn: 96403
* IRgen: Add CreateIRTemp, which creates a temporary alloca but with type ↵Daniel Dunbar2010-02-161-0/+7
| | | | | | converted "not-for-memory". Dunno a better name. llvm-svn: 96374
* When emitting complete destructors for classes with virtual bases, computeJohn McCall2010-02-161-2/+10
| | | | | | | | | | | | the offset to the virtual bases statically inside of relying on the virtual base offsets in the object's vtable(s). This is both more efficient and sound against the destructor's manipulation of the vtables. Also extract a few helper routines. Oh and we seem to pass all tests with an optimized clang now. llvm-svn: 96327
* IRgen: Add CreateMemTemp, for creating an temporary memory object for a ↵Daniel Dunbar2010-02-091-1/+6
| | | | | | | | | | 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. If this bothers you, patches welcome! PR6240. llvm-svn: 95648
