Detailed Description

Consume a parameter from a specific resource list.

Normally the resource list is determined by the parameter data-type, but this action specifies an overriding resource list. Assignment will not fall through to the stack.

◆ assignAddress()

uint4 ghidra::ConsumeAs::assignAddress	(	Datatype *	dt,
		const PrototypePieces &	proto,
		int4	pos,
		TypeFactory &	tlist,
		vector< int4 > &	status,
		ParameterPieces &	res
	)		const

virtual

Assign an address and other meta-data for a specific parameter or for return storage in context.

The Address is assigned based on the data-type of the parameter, available register resources, and other details of the function prototype. Consumed resources are marked. This method returns a response code:

success - indicating the Address was successfully assigned
fail - if the Address could not be assigned
hiddenret_ptrparam - if an additional hidden return parameter is required

Parameters

dt	is the data-type of the parameter or return value
proto	is the high-level description of the function prototype
pos	is the position of the parameter (pos>=0) or return storage (pos=-1)
tlist	is a data-type factory for (possibly) transforming the data-type
status	is the resource consumption array
res	will hold the resulting description of the parameter
