frame.h File Reference

Block.

Extra info for loops and trys (others?) Frames use linked list of blocks to handle nested loops and try-catch blocks.

Block Type.

Numerical values to put in the 'b_type' field of the tPmBlockType struct.

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.

Native Frame.

A struct that holds the execution frame of a native function, including the args and single stack slot, and pointer to the code object.

This struct doesn't need an OD because it is only used statically in the globals struct. There's only one native frame, the global one. This happens because a native function is a leaf node in the call tree (a native func can't call python funcs).

Block Type.

Numerical values to put in the 'b_type' field of the tPmBlockType struct.

Enumerator:

B_INVALID	Invalid block type.
B_LOOP	Loop type.
B_TRY	Try type.
