Dale Johannesen e660f4d072 Use a MemIntrinsicSDNode for ISD::PREFETCH, which touches 
memory, so a MachineMemOperand is useful (not propagated
into the MachineInstr yet).  No functional change except
for dump output.

Andrew Trick 5f88cc34e1 Remove the vector of live vregs. I thought we would need to track 
them, but hopefully we won't. And this is not the right data structure
to do it anyway.

Jim Grosbach 1e4d9a17c2 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

Jakob Stoklund Olesen e4f3317cda After splitting, compute connected components of all new registers, not just for 
the remainder register.

Example:

bb0:
  x = 1
bb1:
  use(x)
  ...
  x = 2
  jump bb1

When x is isolated in bb1, the inner part breaks into two components, x1 and x2:

bb0:
  x0 = 1
bb1:
  x1 = x0
  use(x1)
  ...
  x2 = 2
  x0 = x2
  jump bb1

Rafael Espindola e8ae98817a Implement some relaxations for arithmetic instructions. The limitation 
on RIP relative relocations looks artificial, but this is a superset of
what we were able to do before.

Jason Molenda e6194f17a1 Add an unwind log Printf to note when an eh_frame section is 
loaded/parsed.  Should add timers to this eventually.

Delay getting a full UnwindPlan if it's possible to unwind with
just a fast UnwindPlan.  This keeps us from reading the eh_frame
section unless we hit something built -fomit-frame pointer or we
hit a frame with no symbol (read: no start address) available.

It doesn't look like it is correctly falling back to using the
full UnwindPlan to provide additional registers that the fast
UnwindPlan doesn't supply; e.g. go to the middle of a stack and
ask for r12 and it will show you the value of r12 in frame 0.
That's a bug for tomorrow.

Kalle Raiskila a49d062234 Change v64 datalayout in SPU. 
The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.

John McCall 925b16629d Optimize field space usage in CompoundStmt, LabelStmt, Expr, and CastExpr. 
There's probably still significant padding waste on x86-64 UNIXen, but
the difference in 32-bit compiles should be significant.

There are a lot of Expr nodes left that could lose a word this way.
