Detailed Description

The functions in this section deal with initialization and deinitalization of the libFirm library.

Enumeration Type Documentation

enum firm_kind

A list of firm kinds.

Most important data structures in firm contain a firm_kind field at the beginning so given void* pointer you can usually still guess the kind of thing the pointer points to. This is used in debug helper functions and printers.

Enumerator
k_BAD	An invalid firm node.
k_entity	An entity.
k_type	A type.
k_ir_graph	An IR graph.
k_ir_node	An IR node.
k_ir_mode	An IR mode.
k_tarval	A tarval.
k_ir_loop	A loop.
k_ir_max	maximum value – illegal for firm nodes.

Function Documentation

firm_kind get_kind

(

const void *

firm_thing

)

Returns the kind of a thing.

Parameters

firm_thing

pointer representing a firm object

void ir_finish

(

void

)

Frees all memory occupied by the firm library.

const char* ir_get_version_build

(

void

)

returns string describing libFirm build

unsigned ir_get_version_major

(

void

)

returns the libFirm major version number

unsigned ir_get_version_micro

(

void

)

returns libFirm micro version number

unsigned ir_get_version_minor

(

void

)

returns libFirm minor version number

const char* ir_get_version_revision

(

void

)

returns string describing libFirm revision

void ir_init

(

void

)

Initializes the firm library and prepares code generation for the host.

This is a convenince function that does:

ir_init_library();
ir_target_set_triple(ir_get_host_machine_triple());
ir_target_init();

void ir_init_library

(

void

)

Initializes the firm library but does not prepare for any code generation.

This is typically followed by target initialization (

Target Setup and Information, ir_target_set(), ir_target_set_triple(), ir_target_init()) to get mode_P defined, a number of transformations also depend on Target Setup and Information information being available.
