a5fc80c2c6 Back out the thread-safe ManagedStatic for now. Too many people have too many problems with it for the moment.

was overenthusiastically deleted in r70234.

28cf31b990 Make sure the CXXFLAGS setting is picked up by 
the common Makefile.  Not sure why this suddenly
started causing problems.

fa57451cf5 Help DejaGnu avoid pipe-jam by producing less output from certain test cases. 
When a test fails with more than a pipeful of output on stdout AND stderr, one
of the DejaGnu programs blocks. The problem can be avoided by redirecting
stdout to a file.

94c30c8409 Pass to verify generated machine code. 
The following is checked:

* Operand counts: All explicit operands must be present.

* Register classes: All physical and virtual register operands must be
  compatible with the register class required by the instruction descriptor.

* Register live intervals: Registers must be defined only once, and must be
  defined before use.

The machine code verifier is enabled with the command-line option
'-verify-machineinstrs', or by defining the environment variable
LLVM_VERIFY_MACHINEINSTRS to the name of a file that will receive all the
verifier errors.

5fe69fa68e Split out the Dwarf writer stuff into separate files. This is a much more 
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!

fab0ee79db Implement a !foreach operator analogous to GNU make's $(foreach). 
Use it on dags and lists like this:

class decls {
  string name;
}

def Decls : decls;

class B<list<string> names> : A<!foreach(Decls.name, names, !strconcat(Decls.name, ", Sr."))>;

26054a566e Implement a !subst operation simmilar to $(subst) in GNU make to do 
def/var/string substitution on generic pattern templates.  For example:

def Type;
def v4f32 : Type;
def TYPE : Type;

class GenType<Type t> {
  let type = !(subst TYPE, v4f32, t);
}

def TheType : GenType<TYPE>;

c778e8bf21 Add an Atomic.h to the System library, for providing a platform independent API 
to low-level sync operations.

The only one present at the moment is MemoryFence(), and only for the platforms
for which I could easily discern the proper way to do it.  If your favorite platform
isn't represented, patches are welcome!

bed3aeff20 Update the names of the exception handling sjlj instrinsics to 
llvm.eh.sjlj.* for better clarity as to their purpose and scope. Add
a description of llvm.eh.sjlj.setjmp to ExceptionHandling.html.

added).

a68cfc68f8 There's yet more ugliness (surprise!) in DebugInfo. This needs major reworking. 
Basically, there was a situation where it was getting an empty vector and doing
a .back() on that. Which isn't cool.

35ad062490 The IfConverter::MergeBlocks method appears to be used only to merge a basic 
block with its unique predecessor.  Change the code to assert if that is not
the case, instead of trying to handle situations where the block has
multiple predecessors.
