Detailed Description

ir_prog keeps information about a program:

A reference point to the method to be executed on program start.
A list of all procedures.
A list of all types.
A global type that contains all global variables and procedures that do not belong to a class. This type represents the data segment of the program. It is not the base class of all classes in a class hierarchy (as, e.g., "object" in java).
A degenerated graph that contains constant expressions.
the output file name

Typedef Documentation

typedef struct ir_prog ir_prog

Program.

Definition at line 90 of file firm_types.h.

Enumeration Type Documentation

enum ir_segment_t

Segment.

A progrom has a number of special segments at the toplevel which modify the behaviour of the entities in them.

Enumerator:

IR_SEGMENT_GLOBAL	"normal" global data
IR_SEGMENT_THREAD_LOCAL	thread local storage segment
IR_SEGMENT_CONSTRUCTORS	the constructors segment. Contains pointers to functions which are executed on module initialization (program start or when a library is dynamically loaded)
IR_SEGMENT_DESTRUCTORS	like constructors, but functions are executed on module exit

Definition at line 60 of file irprog.h.

enum irp_resources_t

Resources usable by algorithms modifying the program.

Enumerator:

IRP_RESOURCE_NONE	no resource
IRP_RESOURCE_IRG_LINK	irg link field See Also set_irg_link(), get_irg_link()
IRP_RESOURCE_ENTITY_LINK	entity link field See Also set_entity_link(), get_entity_link()
IRP_RESOURCE_TYPE_VISITED	type visited field See Also type_visited(), mark_type_visited(), inc_master_type_visited()
IRP_RESOURCE_TYPE_LINK	type link field See Also set_type_link(), get_type_link()

Definition at line 91 of file irprog.h.

Function Documentation

void add_irp_asm ( ident * asm_string )

Add a new global asm include.

void free_ir_prog ( void )

Frees all memory used by irp.

Types in type list and irgs in irg list must be freed by hand before.

ir_graph* get_const_code_irg ( void )

Returns the graph for global constants of the current irp.

Returns an irgraph that only contains constant expressions for constant entities. Do not use any access function for this graph, do not generate code for this graph. This graph contains only one block. The constant expressions may not contain control flow. Walking the graph starting from any node will not reach the block or any controlflow. See also copy_const_code() in entity.h.

ir_type* get_glob_type ( void )

Returns the "global" type of the irp.

Upon creation this is an empty class type. This is a convenience function for get_segment_type(IR_SEGMENT_GLOBAL)

ir_prog* get_irp ( void )

Returns the current irp from where everything in the current module can be accessed.

See Also: irp

ident* get_irp_asm ( size_t pos )

Returns the global asm include at position pos.

irg_callee_info_state get_irp_callee_info_state ( void )

Returns callee info state for the whole program.

See Also: get_irg_callee_info_state()

ident* get_irp_ident ( void )

Returns the name of the current irp.

ir_graph* get_irp_irg ( size_t pos )

Returns the ir graph at position pos in the irp.

size_t get_irp_last_idx ( void )

returns the biggest not used irg index number

ir_graph* get_irp_main_irg ( void )

Returns the main routine of the compiled program.

size_t get_irp_n_asms ( void )

Returns the number of global asm includes.

size_t get_irp_n_irgs ( void )

Returns the number of ir graphs in the irp.

size_t get_irp_n_types ( void )

Returns the number of all types in the irp.

const char* get_irp_name ( void )

Returns the name of the current irp.

ir_label_t get_irp_next_label_nr ( void )

Returns a new, unique label number.

ir_type* get_irp_type ( size_t pos )

Returns the type at position pos in the irp.

ir_type* get_segment_type ( ir_segment_t segment )

Returns the type containing the entities for a segment.

Parameters

segment the segment

ir_type* get_tls_type ( void )

Returns the "thread local storage" type of the irp.

Upon creation this is an empty struct type. This is a convenience function for get_segment_type(IR_SEGMENT_THREAD_LOCAL)

void irp_free_resources	(	ir_prog *	irp,
		irp_resources_t	resources
	)

Frees resources availabel for a whole program.

int irp_prog_name_is_set ( void )

Returns true if the user ever set a program name.

void irp_reserve_resources	(	ir_prog *	irp,
		irp_resources_t	resources
	)

Reserve resources available for a whole program.

This is a debug tool: All code should properly allocate the resources it uses so if two interlocked algorithms use the same resources that bug will get detected.

irp_resources_t irp_resources_reserved ( const ir_prog * irp )

Returns currently reserved whole program resources.

ir_prog* new_ir_prog ( const char * name )

Creates a new ir_prog (a module or compilation unit).

Note: This does not set irp to the newly created ir_prog

Parameters

name	the name of this irp (module)

void set_irp ( ir_prog * irp )

Sets current irp.

void set_irp_callee_info_state ( irg_callee_info_state s )

Sets callee info state for the whole program.

See Also: set_irg_callee_info_state()

void set_irp_irg	(	size_t	pos,
		ir_graph *	irg
	)

Sets the ir graph at position pos.

void set_irp_main_irg ( ir_graph * main_irg )

Sets the main routine of the compiled program.

void set_irp_prog_name ( ident * name )

Sets the file name / executable name or the like.

Initially the ident 'no_name_set'.

void set_irp_type	(	size_t	pos,
		ir_type *	typ
	)

Overwrites the type at position pos with another type.

void set_segment_type	(	ir_segment_t	segment,
		ir_type *	new_type
	)

Changes a segment segment type for the program.

(use with care)

Variable Documentation

ir_prog* irp

A variable pointing to the current irp (program or module).

This variable should be considered constant. Moreover, one should use get_irp() to get access the the irp.

Note: Think of the irp as the "handle" of a program.
