hex.push_ret_address

Effectively:  stack[++sp] = return_address
Pushes the given return_address to the next cell in the stack. Increments sp.
Note: the pushed returned address must be popd out afterwards with pop_ret_address.
return_address is a fj-op address, so we assume is dw-aligned.

Signature

def push_ret_address return_address < hex.pointers.sp { ... }

Defined in hex/pointers/stack.fj — lines 39–43 (view on GitHub).

Complexity

• Time: w(2.25@+10) +  9@+ 51

• Space: w(2.62@+49) + 20@+231
