psyclone.psyir.nodes.value_range_check_node#
This module provides support for verifying that the real inputs and outputs of a kernel are valid numbers (i.e. neither NAN nor infinite).
Classes#
ValueRangeCheckNode: This class can be inserted into a Schedule to mark Nodes for
- class psyclone.psyir.nodes.value_range_check_node.ValueRangeCheckNode(ast=None, children=None, parent=None, options=None)[source]#
This class can be inserted into a Schedule to mark Nodes for NAN-checking using the NanTestTrans transformation. The Nodes marked for checking become children of (the Schedule of) a ValueRangeCheckNode.
Inheritance
- lower_to_language_level()[source]#
Lowers this node (and all children) to language-level PSyIR. The PSyIR tree is modified in-place.
- Returns:
the lowered version of this node.
- Return type:
psyclone.psyir.node.Node
- property value_range_check_body#
- Returns:
the Schedule associated with this ValueRangeCheckNode.
