Partial-Element Getter

This function extracts a portion of an integer value from a PartialElement. The BitField implementations call it as they assemble a complete integer. It performs the following steps:

1. the PartialElement is loaded (and masked to discard unused bits),
2. the loaded value is then shifted to abut the LSedge of the stack local,
3. and then resized into a U value.

Type Parameters

• O and T are the type parameters of the PartialElement argument.
• U is the destination integer type.

Parameters

• elem: A PartialElement containing a value segment.
• shamt: The distance by which to right-shift the value loaded from elem so that it abuts the LSedge.

Returns

The segment of an integer stored in elem.
