NAME

Parrot::Pmc2c::PMC - PMC model object

SYNOPSIS

use Parrot::Pmc2c::PMC;

DESCRIPTION

Parrot::Pmc2c::PMC is used by tools/build/pmc2c.pl to generate C code from PMC files.

Functions

is_dynpmc

Determines if a given PMC type is dynamically loaded or not.

implements_vtable($method)

True if pmc generates code for vtable $method.

vtable_method_does_write($method)

Returns true if the vtable $method writes our value.

inherit_attrs()

$class = inherit_attrs($class, $meth);

Purpose: Modify $attrs to inherit attrs from $super_attrs as appropriate.

Arguments: List of two arguments:

  • Method name.

Return Values: Reference to hash holding the data structure being built up within dump_pmc().

Comments: Called within gen_super_meths().

These are auxiliary subroutines called inside the methods described above.

dump_is_current()

dump_is_current($existing);

Purpose: Determines whether the dump of a file is newer than the PMC file. (If it's not, then the PMC file has changed and the dump has not been updated.)

Arguments: String holding filename.

Return Values: Returns true if timestamp of existing is more recent than that of PMC.

Comments: Called within dump_pmc().

generate_c_file()

Generates the C implementation file code for the PMC.

generate_h_file()

Generates the C header file code for the PMC.

hdecls()

Returns the C code function declarations for all the methods for inclusion in the PMC's C header file.

Instance Methods

init()

Initializes the instance.

gen_includes()

Returns the C #include for the header file of each of the PMC's superclasses.

pre_method_gen

Generate switch-bases VTABLE for MULTI

post_method_gen

Generate write barriers.

gen_methods()

Returns the C code for the pmc methods.

gen_attributes()

Returns the C code for the attribute struct definition.

find_multi_functions()

Returns an arrayref of MULTI function names declared in the PMC. Used to initialize the multiple dispatch function list.

vtable_flags()

Returns C code to produce a PMC's flags.

vtable_decl($name)

Returns the C code for the declaration of a vtable temporary named $name with the functions for this class.

pmc_class_init_func()

Returns the C code for the PMC's class_init function as a static function to be called from the exported class_init.

init_func()

Returns the C code for the PMC's initialization method, or an empty string if the PMC has a no_init flag.

update_vtable_func()

Returns the C code for the PMC's update_vtable.

get_mro_func()

Returns the C code for the PMC's get_mro function.

get_isa_func()

Returns the C code for the PMC's get_isa function.

get_vtable_func()

Returns the C code for the PMC's update_vtable.

gen_switch_vtable

Generate switch-bases VTABLE for MULTI

generate_start

Generate and emit the C code for the start of an attribute struct.

generate_end

Generate and emit the C code for the end of an attribute struct.

generate_declaration

Generate and emit the C code for an attribute declaration.

generate_accessor

Generate and emit the C code for an attribute get/set accessor pair.
