buildMinMaxReductionSeq()

static Value buildMinMaxReductionSeq ( Location  loc, arith::CmpIPredicate  predicate, ValueRange  values, OpBuilder &  builder  )

static

Given a range of values, emit the code that reduces them with "min" or "max" depending on the provided comparison predicate, sgt for max and slt for min.

Multiple values are scanned in a linear sequence. This creates a data dependences that wouldn't exist in a tree reduction, but is easier to recognize as a reduction by the subsequent passes.
