Modules
	Argument location types

	Standard C-language models for x86

Classes
struct	rrel_t
	Register-relative argument location. More...

struct	custloc_desc_t

class	argloc_t
	Describes an argument location. More...

struct	argpart_t
	Subsection of an argument location. More...

class	scattered_aloc_t
	Used to manage arguments that are described by multiple locations (also see ALOC_DIST) More...

struct	aloc_visitor_t
	Visit all argument locations. More...

struct	const_aloc_visitor_t
	Same as aloc_visitor_t, but may not modify the argloc. More...

Typedefs
typedef int	argloc_type_t
	Specifies the location type of a function argument - see Argument location types.

typedef qvector< argloc_t >	arglocs_t
	vector of argument locations

Enumerations
enum	argreg_policy_t { ARGREGS_POLICY_UNDEFINED, ARGREGS_GP_ONLY, ARGREGS_INDEPENDENT, ARGREGS_BY_SLOTS, ARGREGS_FP_CONSUME_GP }
	Function argument passing: how GP & FP registers cooperate with each other. More...

Functions

	Convert an argloc to human readable form.

idaman int ida_export	for_all_arglocs (aloc_visitor_t &vv, argloc_t &vloc, int size, int off=0)
	Compress larger argloc types and initiate the aloc visitor.

int idaapi	for_all_const_arglocs (const_aloc_visitor_t &vv, const argloc_t &vloc, int size, int off=0)
	See for_all_arglocs()

THREAD_SAFE cm_t	get_cc (cm_t cm)
	Get the calling convention.

THREAD_SAFE bool	is_user_cc (cm_t cm)
	Does the calling convention specify argument locations explicitly?

THREAD_SAFE bool	is_vararg_cc (cm_t cm)
	Does the calling convention use ellipsis?

THREAD_SAFE bool	is_purging_cc (cm_t cm)
	Does the calling convention clean the stack arguments upon return?. More...

Enumeration Type Documentation

Function argument passing: how GP & FP registers cooperate with each other.

Enumerator
ARGREGS_GP_ONLY	GP registers used for all arguments.
ARGREGS_INDEPENDENT	FP/GP registers used separately (like gcc64)
ARGREGS_BY_SLOTS	fixed FP/GP register per each slot (like vc64)
ARGREGS_FP_CONSUME_GP	FP register also consumes one or more GP regs but not vice versa (aix ppc ABI)

idaman int ida_export verify_argloc	(	const argloc_t &	vloc,
		int	size,
		const rangeset_t *	gaps
	)

Parameters

size	total size of the variable
gaps	if not NULL, specifies gaps in structure definition. these gaps should not map to any argloc, but everything else must be covered

idaman bool ida_export optimize_argloc	(	argloc_t *	vloc,
		int	size,
		const rangeset_t *	gaps
	)

Verify and optimize scattered argloc into simple form.

All new arglocs must be processed by this function.

Return values

true	success
false	the input argloc was illegal

THREAD_SAFE bool is_purging_cc ( cm_t cm )
