Dynamic memory allocation in compiler design
WebEach block will be an fixed size array (usually 16 or 32 per block) of records and it is obtained from the standard memory manager. A free list will also be maintained for linking the free records in their blocks. To begin the system will start with an empty free list and zero blocks. The first allocation request will find the free list empty and. WebNov 8, 2024 · This block of memory is called storage management. One of the important tasks that a compiler must perform is to allocate the resources of the target machine to represent the data objects that are being manipulated by the source program. A compiler must decide the runtime representation of the data objects in the source program.
