Mark negative-zero-to-int conversion as Inexact,
since -0.0 can't be represented as an int.
This prevents llvm from reducing -0.0 to a

Be more precise about which conversions of NaNs

This includes not marking a GEP involving a vector as unsafe, but only when it

Actually run Obj-C++ tests if llvm-gcc supports.
Before there were two problems: (1) configure
turned "obj-c++" into "obj" in the langs line;
(2) the dejagnu library called it objc++ not
obj-c++.
Now the problem is that some of these tests don't
pass!

Clarify the relationship between byval and readonly/
readnone.  Make clearer that readnone functions do not
dereference pointer arguments.  Do not use the highly

such as throwing an exception, or looping for ever).

Avoid creating two TargetLowering objects for each target.
Instead, just create one, and make sure everything that needs
it can access it. Previously most of the SelectionDAGISel
subclasses all had their own TargetLowering object, which was
redundant with the TargetLowering object in the TargetMachine
subclasses, except on Sparc, where SparcTargetMachine
didn't have a TargetLowering object. Change Sparc to work
more like the other targets here.

The result of getSetCCResultType (eg: i32) may be larger
than the type an i1 is promoted to (eg: i8).  Account
for this.  Noticed by Tilmann Scheller on CellSPU; he
will hopefully take care of fixing this in LegalizeDAG
and adding a testcase!

Teach internalize to preserve the callgraph.
Why?  Because it was there!

Acquire the lock only when necessary. More precisely, do not acquire
the lock when calling a method which may materialize the llvm::Function.

SplitBlock should only attempt to update LoopInfo if it is actually being used.

Implement fast-isel support for zero-extending from i1.
It turns out that this is a fairly common operation,
and it's easy enough to handle.

Fix X86FastISel to handle dynamic allocas that have avoided
getting inserted into the ValueMap. This avoids infinite
recursion in some rare cases.

Unbreak the build.

Fix a typo.

Add support for Canadian Cross builds where the host executables are not
runnable on the build machine.

There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.

Thanks to Eric C. and Devang P. for pre-commit review.

Fix build breakage.

Forgot to include Makefile.plugins.

Optimize conditional branches in X86FastISel. This replaces
sequences like this:
       sete    %al
       testb   %al, %al
       jne     LBB11_1
with this:
       je      LBB11_1

Add a new MachineBasicBlock utility function, isLayoutSuccessor, that
can be used when deciding if a block can transfer control to another
via a fall-through instead of a branch.

Build system tweaks to make it more convenient for the plugin authors.

Plugins can be now compiled in with a slight Makefile change.
For example, to compile the new Clang driver, use:

cd $LLVMC2_DIR
make TOOLNAME=ccc2 BUILTIN_PLUGINS=Clang

fix build gcc 4.3

Use a multimap rather than a map for holding the list of copies to insert, so we don't lose copies when two of them have
the same source.  I don't know what I was thinking when I wrote this originally.
Note: There's probably a more efficient way to do this, but I need to think about it some more, and about what determinism
guarantees need to be present.

Handle some 64-bit atomics on x86-32, some of the time.

Avoid name shadowing with E variable defined in for(). This was giving VC++
grief.

Fix a think-o in isSafeToMove. This fixes it from thinking that
volatile memory references are safe to move.
