Bill Wendling b912351ec9 Added some comments and reformatted others. No functionality change. 
Added two "FIXMEs" for code that looks dubious to me (but I could be
wrong).

llvm-svn: 47366
 2008-02-20 09:15:16 +00:00
Bill Wendling 34c09e1a78 Fixed typo.

Nick Lewycky b0a2f9513f Use getConstant for ConstantInts. 
llvm-svn: 47361
 2008-02-20 06:58:55 +00:00
Nick Lewycky 1c44ebcf86 Add 'umax' similar to 'smax' SCEV. Closes PR2003. 
Parse reversed smax and umax as smin and umin and express them with negative
or binary-not SCEVs (which are really just subtract under the hood).

Parse 'xor %x, -1' as (-1 - %x).

Remove dead code (ConstantInt::get always returns a ConstantInt).

Don't use getIntegerSCEV(-1, Ty). The first value is an int, then it gets
passed into a uint64_t. Instead, create the -1 directly from
ConstantInt::getAllOnesValue().

Chris Lattner 2a8037b5f5 Fix an incredibly subtle bug exposed by Ted's change to APInt profiling. 
AddNodeIDNode does profiling for a ConstantSDNode, but so does 
SelectionDAG::getConstant.  This profiling should be moved to a common
static function in ConstantSDNode.
