Detailed Description
Frame.
A struct that holds the execution frame of a function, including the stack, local vars and pointer to the code object.
This struct doesn't declare the stack. frame_new() is responsible for allocating the extra memory at the tail of fo_locals[] to hold both the locals and stack.
Definition at line 83 of file frame.h.
