callback.* is that the queue is emptied when the callbacks have
been called, and that it's designed for large amounts of
callbacks. Used primarily by the gc.

an evaluator for constant expressions and dooptcode which wraps
together the conversion of a node tree for a function body to
optimized byte code.

basic opcode table stuff.

Wrap together the peephole optimizer, handle the conversion of
labels from opcodes to offsets, and the conversion from opcode
sequences to machine code. Also have some primitives for opcodes

is wrapped together here. Also contain the lfun support, the C
level parts of the resolver, and the trampoline program.

pushing and popping various data types.

Macros for the opcode prototypes. Extracted from
Wraps up the opcodes in interpret_functions.h into an eval

when machine code isn't enabled. The opcodes become separate
functions otherwise. Included by interpret.c.
