2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25When performing a ::delete of an object with a virtual destructor,John McCall
be sure to delete the complete object pointer, not the original pointer. This is necessary if the base being deleted is at a non-zero offset in the complete object. This is only required for objects with virtual destructors because deleting an object via a base-class subobject when the base does not have a virtual destructor is undefined behavior. Noticed while reviewing the last four years of cxx-abi-dev activity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164597 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Whether an argument is required (in contrast with being anJohn McCall
optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150788 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-16Revert "Make CXXNewExpr contain only a single initialier, and not hold the ↵Sebastian Redl

2012-02-16Make CXXNewExpr contain only a single initialier, and not hold the used ↵Sebastian Redl
constructor itself. Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities. This breaks the static analysis of new expressions. I've filed PR12014 to track this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150682 91177308-0d34-0410-b5e6-96231b3b80d8
