NAME

src/pmc/oplib.pmc - Information about an opcode library

DESCRIPTION

The PMC provides introspection on the opcodes contained in a library.

Vtable functions

void init()

Throws an error. OpLib requires an argument to init. See init_pmc.

void init_pmc(PMC *name_pmc)

Initializes the OpLib with information about an oplib.

INTVAL get_integer_keyed_str(STRING *name)

INTVAL get_integer_keyed(PMC *key)

PMC* get_pmc_keyed_str(STRING *name)

PMC* get_pmc_keyed(PMC *key)

Look up an op number given the name of the op. First we look for the specific name, then the more general short name.The VTABLEs that return integers return -1 when an opcode could not be found. The VTABLEs that return PMCs throw exceptions instead.

PMC* get_pmc_keyed_int(INTVAL value)

Returns an Opcode PMC for a given opcode number. To find an opcode number from a name, see get_integer_keyed_str() above.

INTVAL elements()

INTVAL get_integer()

Returns the number of opcodes in the library.

void* get_pointer()

Returns the op_lib_t pointer for the opcode library.

Methods

PMC *op_family(STRING *shortname)

Returns an array of Opcode PMCs for all the opcodes in the library that share the given short name.

PMC *version()

Returns an array containing the two bytecode version numbers (bc_major, bc_minor) of the library.
