psyclone.psyir.transformations.intrinsics.max2code_trans

Module providing a transformation from a PSyIR MAX intrinsic to PSyIR code. This could be useful if the MAX intrinsic is not supported by the back-end or if the performance of the inline code is better than the intrinsic.

Classes

• Max2CodeTrans: Provides a transformation from a PSyIR MAX Intrinsic node to

class psyclone.psyir.transformations.intrinsics.max2code_trans.Max2CodeTrans

Provides a transformation from a PSyIR MAX Intrinsic node to equivalent code in a PSyIR tree. Validity checks are also performed (by a parent class).

The transformation replaces

R = MAX(A, B, C ...)

with the following logic:

R = A
if B > R:
    R = B
if C > R:
    R = C
...

Inheritance

apply(node, options=None, **kwargs)

Applies the Max2CodeTrans to the provided node.

Parameters:

• node (psyclone.psyir.nodes.IntrinsicCall) – a MAX intrinsic.

• options (Optional[Dict[str, Any]]) – a dictionary with options for transformations.
