		Array< PrimExpr >	equal,
		Array< PrimExpr >	upper
	)

equal	equalities
upper	the upper bounds (include)

Member Function Documentation

FindBestRange()

Range tvm::arith::IntGroupBounds::FindBestRange

(

const Map< Var, Range > &

vranges_addl = {}

)

const

Find the best range from the grouped bounds.

Parameters

vranges_addl

additional variable ranges that help infer the best range.

Returns

The best range (has the least difference between the lower bound and upper bound). undefined if (-inf, +inf).

FromRange()

static IntGroupBounds tvm::arith::IntGroupBounds::FromRange ( const Range &  r )

static

Construct bounds from a range.

Parameters

r

The range

Returns

constructed bounds.

operator+()

IntGroupBounds tvm::arith::IntGroupBounds::operator+

(

const Range &

r

)

Combine the bounds with another range.

Parameters

r	range to be combined.

Returns

combined bounds.

Substitute()

IntGroupBounds tvm::arith::IntGroupBounds::Substitute

(

const Map< Var, PrimExpr > &

subst

)

const

Perform substitution on all components of the struct.
