This patch just swaps in the new data structure; the rest of the code works as before by allowing the ObjCInterfaceDecl* to be null. llvm-svn: 52653

| | | | | | | | also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet." Patch by David Chisnall! llvm-svn: 52599

This addresses: <rdar://problem/5968508> checker gives misleading report for dead store in loop 2) Don't emit a dead store warning when assigning a null value to a pointer. This is a common form of defensive programming. We may wish to make this an option to the the checker one day.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clang as a Release build. The big change is that all AST nodes (subclasses of Stmt) whose children are Expr* store their children as Stmt* or arrays of Stmt*. This is to remove strict-aliasing warnings when using StmtIterator. None of the interfaces of any of the classes have changed (except those with arg_iterators, see below), as the accessor methods introduce the needed casts (via cast<>). While this extra casting may seem cumbersome, it actually adds some important sanity checks throughout the codebase, as clients using StmtIterator can potentially overwrite children that are expected to be Expr* with Stmt* (that aren't Expr*). The casts provide extra sanity checks that are operational in debug builds to catch invariant violations such as these. For classes that have arg_iterators (e.g., CallExpr), the definition of arg_iterator has been replaced. Instead of it being Expr**, it is an actual class (called ExprIterator) that wraps a Stmt**, and provides the necessary operators for iteration. The nice thing about this class is that it also uses cast<> to type-checking, which introduces extra sanity checks throughout the codebase that are useful for debugging. A few of the CodeGen functions that use arg_iterator (especially from OverloadExpr) have been modified to take begin and end iterators instead of a base Expr** and the number of arguments. This matches more with the abstraction of iteration. This still needs to be cleaned up a little bit, as clients expect that ExprIterator is a RandomAccessIterator (which we may or may not wish to allow for efficiency of representation). This is a fairly large patch. It passes the tests (except CodeGen/bitfield.c, which was already broken) on both a Debug and Release build, but it should obviously be reviewed. llvm-svn: 52378

This also fixes the crash in PR2406, but doesn't completely fix the issue; it appears there's something strange about the physical location for the definition of int64_t in stdlib.h. llvm-svn: 52209

| | | | | | | | | | | | | | | pointer cast hack currently in isIntegerConstantExpr (in lib/AST/Expr.cpp). Also removes an odd test that even gcc doesn't accept. The reason the pointer cast hack is relevant here is that it makes Sema end up misinterpreting the relevant expression as a null pointer constant. The reason for this patch is that I plan to remove the pointer cast hack sometime soon because it causes strange issues, especially in its current form; see my recent email to cfe-dev "[PATCH] add constant expression evaluation to the AST and fix PR2413". llvm-svn: 52120
