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 functionality, which is implemented in this file.

These stacks all differ only in the size of items.

Functions

void stack_system_init(Interp *interp)

Called from make_interpreter() to initialize the interpreter's register stacks.

Stack_Chunk_t *register_new_stack(Interp *interp, const char *name, size_t item_size)

Create a new stack and name it. stack->name is used for debugging/error reporting.

Stack_Chunk_t *cst_new_stack_chunk(Interp *interp, const Stack_Chunk_t *chunk)

Get a new chunk either from the freelist or allocate one.

void *stack_prepare_push(Parrot_Interp interp, Stack_Chunk_t **stack_p)

Return a pointer, where new entries go for push.

void *stack_prepare_pop(Parrot_Interp interp, Stack_Chunk_t **stack_p)

Return a pointer, where new entries are poped off.
