Change encoding of instruction operands in bitcode binaries to be relative
to the instruction position. The old encoding would give an absolute
ID which counts up within a function, and only resets at the next function.
I.e., Instead of having:
... = icmp eq i32 n-1, n-2
br i1 ..., label %bb1, label %bb2
it will now be roughly:
... = icmp eq i32 1, 2
br i1 1, label %bb1, label %bb2
This makes it so that ids remain relatively small and can be encoded
in fewer bits.
With this encoding, forward reference operands will be given
negative-valued IDs. Use signed VBRs for the most common case
of forward references, which is phi instructions.
To retain backward compatibility we bump the bitcode version
from 0 to 1 to distinguish between the different encodings.

This patch addresses PR13947.
For function calls on the 64-bit PowerPC SVR4 target, each parameter
is mapped to as many doublewords in the parameter save area as
necessary to hold the parameter. The first 13 non-varargs
floating-point values are passed in registers; any additional
floating-point parameters are passed in the parameter save area. A
single-precision floating-point parameter (32 bits) must be mapped to
the second (rightmost, low-order) word of its assigned doubleword
slot.
Currently LLVM violates this ABI requirement by mapping such a
parameter to the first (leftmost, high-order) word of its assigned
doubleword slot. This is internally self-consistent but will not
interoperate correctly with libraries compiled with an ABI-compliant
compiler.
This patch corrects the problem by adjusting the parameter addressing
on both sides of the calling convention.

Practical Dependence Testing
Gina Goff, Ken Kennedy, and Chau-Wen Tseng
PLDI 1991
It cannot yet propagate constraints between coupled RDIV subscripts (discussed
in Section 5.3.2 of the paper).
It's organized as a FunctionPass with a single entry point that supports testing
for dependence between two instructions in a function. If there's no dependence,
it returns null. If there's a dependence, it returns a pointer to a Dependence
which can be queried about details (what kind of dependence, is it loop
independent, direction and distance vector entries, etc). I haven't included
every imaginable feature, but there's a good selection that should be adequate
for supporting many loop transformations. Of course, it can be extended as
necessary.

There is a partially-implemented design decision here that, if a
particular identifier has been defined or #undef'd within the

definitions that come from imported modules. There's still a little
work to do to ensure that the right #undef'ing happens.

Original message:
The attached is the fix to radar://
11663049. The optimization can be outlined by following rules:
(select (x != c), e, c) -> select (x != c), e, x),
(select (x == c), c, e) -> select (x == c), x, e)
where the <c> is an integer constant.
The reason for this change is that : on x86, conditional-move-from-constant needs two instructions;
however, conditional-move-from-register need only one instruction.
While the LowerSELECT() sounds to be the most convenient place for this optimization, it turns out to be a bad place. The reason is that by replacing the constant <c> with a symbolic value, it obscure some instruction-combining opportunities which would otherwise be very easy to spot. For that reason, I have to postpone the change to last instruction-combining phase.

When generating spill and reload code for vector registers on PowerPC,
the compiler makes use of GPR0. However, there are two flavors of
GPR0 defined by the target: the 32-bit GPR0 (R0) and the 64-bit GPR0
(X0). The spill/reload code makes use of R0 regardless of whether we
are generating 32- or 64-bit code.
This patch corrects the problem in the obvious manner, using X0 and
ADDI8 for 64-bit and R0 and ADDI for 32-bit.

The PowerPC VRSAVE register has been somewhat of an odd beast since
the Altivec extensions were introduced. Its use is optional, and
allows the compiler to communicate to the operating system which
vector registers should be saved and restored during a context switch.
In practice, this information is ignored by the various operating
systems using the SVR4 ABI; the kernel saves and restores the entire
register state. Setting the VRSAVE register is no longer performed by
the AIX XL compilers, the IBM i compilers, or by GCC on Power Linux
systems. It seems best to avoid this logic within LLVM as well.
This patch avoids generating code to update and restore VRSAVE for the
PowerPC SVR4 ABIs (32- and 64-bit). The code remains in place for the
Darwin ABI.

Add in support for expansion of all of the comparison operations to the absolute minimum required set. This allows a backend to expand any arbitrary set of comparisons as long as a minimum set is supported.
The minimum set of required instructions is ISD::AND, ISD::OR, ISD::SETO(or ISD::SETOEQ) and ISD::SETUO(or ISD::SETUNE). Everything is expanded into one of two patterns:
Pattern 1: (LHS CC1 RHS) Opc (LHS CC2 RHS)
Pattern 2: (LHS CC1 LHS) Opc (RHS CC2 RHS)

Change the Thread constructor over to take a Process& rather than a ProcessSP. We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP.
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.

legit Sphinx directive. I believe that on my machine Sphinx is falling
back to just displaying it monospace with no syntax, whereas llvm.org's
Sphinx is just discarding it.

Change Sema::PropertyIfSetterOrGetter to make use of isPropertyAccessor.
Old algorithm:

2. Use the name to look up a property in the current ObjCContainer
and all its protocols.
3. If the current container is an interface, also look in all categories
and superclasses (and superclass categories, and so on).
New algorithm:
1. See if the method is marked as a property accessor. If so, look through
all properties in the current container and find one that has a matching
selector.
2. Find all overrides of the method using ObjCMethodDecl's
getOverriddenMethods. This collects methods in superclasses and protocols
(as well as superclass categories, which isn't really necessary), and
checks if THEY are accessors. This part is not done recursively, since
getOverriddenMethods is already recursive.
