annoying warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47367 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-20Added some comments and reformatted others. No functionality change.Bill Wendling
Added two "FIXMEs" for code that looks dubious to me (but I could be wrong). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47366 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-20Use getConstant for ConstantInts.Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47361 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-20Add 'umax' similar to 'smax' SCEV. Closes PR2003.Nick Lewycky
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(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47360 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-20Fix an incredibly subtle bug exposed by Ted's change to APInt profiling.Chris Lattner
AddNodeIDNode does profiling for a ConstantSDNode, but so does SelectionDAG::getConstant. This profiling should be moved to a common static function in ConstantSDNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47359 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-19remove the lower packed pass. It can never work and even the parts that Chris Lattner
could work don't work fully. This fixes PR1705. Oh yeah, we don't have packed types anymore either ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47322 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-18- When DAG combiner is folding a bit convert into a BUILD_VECTOR, it should ↵Evan Cheng
check if it's essentially a SCALAR_TO_VECTOR. Avoid turning (v8i16) <10, u, u, u> to <10, 0, u, u, u, u, u, u>. Instead, simply convert it to a SCALAR_TO_VECTOR of the proper type. - X86 now normalize SCALAR_TO_VECTOR to (BIT_CONVERT (v4i32 SCALAR_TO_VECTOR)).

2008-02-18- Remove the previous check which broke coalescer-commute3.llEvan Cheng
- For now, conservatively ignore copy MI whose source is a physical register.
