"this patch adds code generation hooks for Objective-C constant strings. It 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."

"This maps the -pthread option to -lpthread - this isn't 100% correct,
...
since handling this correctly is quite complex, and on some platforms
requires additional -D options and on some implies linking against a
different libc, but this works better than just ignoring the option.
The other change passes the -x option across to clang, which allows
compiling .c files as Objective-C and so on. For some reason a lot of
configure scripts seem to be under the misguided impression that this
is a sensible thing to do."

Modified the dead stores checker to...

1) Check if a dead store appears as a subexpression. For such cases, we emit
a verbose diagnostic so that users aren't confused. 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.

This patch is motivated by numerous strict-aliasing warnings when compiling
...
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.
