Alexandros Lamprineas	e15c982f6d	[SelectionDAG] swap select_cc operands to enable folding ... The DAGCombiner tries to SimplifySelectCC as follows: select_cc(x, y, 16, 0, cc) -> shl(zext(set_cc(x, y, cc)), 4) It can't cope with the situation of reordered operands: select_cc(x, y, 0, 16, cc) In that case we just need to swap the operands and invert the Condition Code: select_cc(x, y, 16, 0, ~cc) Differential Revision: https://reviews.llvm.org/D53236 llvm-svn: 346484	2018-11-09 11:09:40 +00:00
