Chris Lattner 758ce7260d Fix shift overflow bug that would occur when a field was a full 32-bits
in tblgen.  This is PR2827, thanks to Waldemar Knorr for tracking this
down.

Dan Gohman b486350b15 Move the primary fast-isel top-level comments to FastISel.cpp, where
they'll be a little more visible. Also, update and reword them a bit.

Dan Gohman 843fe14fab Move the code that handles DAGISel error conditions into
helper functions instead of duplicating it inline each time
it is needed. This eliminates a few hundred or so copies
of this code in each target.

Dan Gohman 6e0548336a Rename ConstantSDNode's getSignExtended to getSExtValue, for
consistancy with ConstantInt, and re-implement it in terms
of ConstantInt's getSExtValue.

Devang Patel 4c758ea3e0 Large mechanical patch.
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.

Bill Wendling 8bc392fb1d - Change "ExternalSymbolSDNode" to "SymbolSDNode".
- Add linkage to SymbolSDNode (default to external).
- Change ISD::ExternalSymbol to ISD::Symbol.
- Change ISD::TargetExternalSymbol to ISD::TargetSymbol

These changes pave the way to allowing SymbolSDNodes with non-external linkage.

Dan Gohman ec270fb640 Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* and
ConstantFP* instead of APInt and APFloat directly.

This reduces the amount of time to create ConstantSDNode
and ConstantFPSDNode nodes when ConstantInt* and ConstantFP*
respectively are already available, as is the case in
SelectionDAGBuild.cpp. Also, it reduces the amount of time
to legalize constants into constant pools, and the amount of
time to add ConstantFP operands to MachineInstrs, due to
eliminating ConstantInt::get and ConstantFP::get calls.

It increases the amount of work needed to create new constants
in cases where the client doesn't already have a ConstantInt*
or ConstantFP*, such as legalize expanding 64-bit integer constants
to 32-bit constants. And it adds a layer of indirection for the
accessor methods. But these appear to be outweight by the benefits
in most cases.

It will also make it easier to make ConstantSDNode and
ConstantFPNode more consistent with ConstantInt and ConstantFP.

Dan Gohman effb894453 Rename ConstantSDNode::getValue to getZExtValue, for consistency
with ConstantInt. This led to fixing a bug in TargetLowering.cpp
using getValue instead of getAPIntValue.

Jim Grosbach 56938af9e2 lib/Target/SubtargetFeature.cpp asserts that the FeatureKV[] table be sorted
by its first field, but TableGen doesn't actually enforce creating it that 
way. TableGen sorts the records that will be used to create it by the names 
of the records, not the Name field of those records.

This patch corrects the sort to use the "Name" field of the record as the 
sort key.
