2010-02-17First cut at emitting vcall offsets.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96455 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-17Emit complete constructors and destructors as aliases to base constructorsJohn McCall
and destructors when the two entities are semantically identical, i.e. when the class has no virtual base classes. We only do this for linkage types for which aliases are supported, i.e. internal and external, i.e. not linkonce. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96451 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-17Correctly calculate base offsets for 'this' pointer adjustments involving ↵Anders Carlsson
virtual bases. This can't be tested yet due to lack of vcall offsets :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96441 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16IRgen optimization: cache the value of 'this' and 'vtt' instead ofJohn McCall
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96403 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-16IRgen: Add CreateIRTemp, which creates a temporary alloca but with type ↵Daniel Dunbar
converted "not-for-memory". Dunno a better name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96374 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96355 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96354 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16Fix a bug where we would not emit secondary vtables for bases of a primary base.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96351 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96329 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16More work on the new layout code.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96328 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16When emitting complete destructors for classes with virtual bases, computeJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96327 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Use getLocStart(), instead of getLocEnd(), to record starting location of ↵Devang Patel
objc method. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96245 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Uniformize the names of type predicates: rather than having isFloatTy andDuncan Sands
isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96224 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15When emitting an aggregate into a temporary, make sure we set the alignmentJohn McCall
on the alloca. The fact that codegen makes this class of bug so wonderfully easy to make is embarrassing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96204 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14Improve support for non-virtual 'this' pointer adjustments. With this, it ↵Anders Carlsson
should be possible to use the new vtable layout code for all class hierarchies that do not involve virtual bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96137 91177308-0d34-0410-b5e6-96231b3b80d8

marked 'force_align_arg_pointer'. Almost there; now all I need to do is finish up the backend. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96100 91177308-0d34-0410-b5e6-96231b3b80d8
