From Chris' review: change MemOperandSDNode's constructor to pass its
argument by reference, rather than by value.

llvm-svn: 46960

Change ConstantSDNode to store an APInt instead of a uint64_t, and
begin adding some methods to use it this way.

Avoid needlessly casting away const qualifiers.

SDIsel processes llvm.dbg.declare by recording the variable debug information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc.
Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes.
For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time.

Revert 46556 and 46585. Dan please fix the PseudoSourceValue problem and re-commit.

Add an extra operand to LABEL nodes which distinguishes between debug, EH, or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution.

Rename ISD::FLT_ROUNDS to ISD::FLT_ROUNDS_ to avoid conflicting
with the real FLT_ROUNDS (defined in <float.h>).

Create a new class, MemOperand, for describing memory references
in the backend. Introduce a new SDNode type, MemOperandSDNode, for
holding a MemOperand in the SelectionDAG IR, and add a MemOperand
list to MachineInstr, and code to manage them. Remove the offset
field from SrcValueSDNode; uses of SrcValueSDNode that were using
it are all all using MemOperandSDNode now.

Also, begin updating some getLoad and getStore calls to use the
PseudoSourceValue objects.

Most of this was written by Florian Brander, some
reorganization and updating to TOT by me.

not it is safe to xform things like fp_extend(fp_round(x)) -> x.

More CellSPU refinement and progress:

- Cleaned up custom load/store logic, common code is now shared [see note
below], cleaned up address modes

- More test cases: various intrinsics, structure element access (load/store
test), updated target data strings, indirect function calls.

Note: This patch contains a refactoring of the LoadSDNode and StoreSDNode
structures: they now share a common base class, LSBaseSDNode, that
provides an interface to their common functionality. There is some hackery
to access the proper operand depending on the derived class; otherwise,
to do a proper job would require finding and rearranging the SDOperands
sent to StoreSDNode's constructor. The current refactor errs on the
side of being conservatively and backwardly compatible while providing
functionality that reduces redundant code for targets where loads and
stores are custom-lowered.
