Macros

stl

• 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 — Initializes a stack of size n (maximal capacity of n hexes / return-addresses).

• stl.call/1 — Saves the return address to the stack and jumps to the given “address”.

• stl.call/2 — Saves the return address to the stack and jumps to the given “address”.

• stl.return — Returns to the calling function (gets the return-address from the top of the stack).

• 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.
