———- Init

Macros¶

stl.ptr_init — NOTE: must be placed just after the startup, so that the read_ptr_byte_table will be in address 256.
stl.stack_init — n is the size of the stack.
stl.call/1 — note: the pop_ret_address is for the future return (counts as space, but not time, complexity).
stl.call/2 — note: the pop_ret_address is for the future return (counts as space, but not time, complexity).
stl.return — note: jumps to the last-call’s pop_ret_address (which this macro counts as time, but not space, complexity).
stl.get_sp — (Unsafe if dst overlaps with hex.pointers.sp).
stl.fcall — Jumps to label, and saves the return address in the given "ret_reg" variable.
stl.fret — Return into the address written in the "ret_reg" variable.
