NAME 
src/stack_common.c - Common stack handling routines for Parrot
DESCRIPTION
Both the register stacks and stacks implemented in src/stacks.c have a common funcionality, which is implemented in this file.
These stacks all differ only in the size of items.
Functions
void stack_system_init(Interp *interpreter)- Called from
make_interpreter()to initialize the interpreter's register stacks. Stack_Chunk_t *register_new_stack(Interp *interpreter, const char *name, size_t item_size)- Create a new stack and name it.
stack->nameis used for debugging/error reporting. Stack_Chunk_t *cst_new_stack_chunk(Interp *interpreter, Stack_Chunk_t *)- Get a new chunk either from the freelist or allocate one.
void *stack_prepare_push(Parrot_Interp interpreter, Stack_Chunk_t **stack_p)- Return a pointer, where new entries go for push.
void *new_register_frame(Parrot_Interp interpreter, Stack_Chunk_t **stack_p)- Like above for the register frame stack. If possible get new chunk from the frame stack cache.
- <void add_to_fp_cache(Interp* interpreter, Stack_Chunk_t *stack_p)>
- Add a register frame to to the register frame stack cache.
void *stack_prepare_pop(Parrot_Interp interpreter, Stack_Chunk_t **stack_p)- Return a pointer, where new entries are poped off.
