Reid Spencer e0fc4dfc22 For PR950: 
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

Owen Anderson e223754ff4 Add support for the new "target data" information in .ll files. This provides 
a better encoding of the targets data layout, rather than trying to guess it
from the endianness and pointersize like before.

one separately.

Chris Lattner bd9acad805 When SimplifySetCC was moved to the DAGCombiner, it was never removed from 
SelectionDAG and it has since bitrotted.  Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.

This fixes obscure bugs.

llvm-svn: 30850
 2006-10-10 01:44:58 +00:00
Evan Cheng 0a2a4b1fbe Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes. 
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.

Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).

Added alignment info (not yet used) and isVolatile fields.
