A framepointer or frame pointer is a pointer to the current stack frame. It is generally used for debugging, but can also be used for stack management in general; the 68k processor series has instruction set support for framepointer access. Linux keeps track of the framepointer for each thread. In computer science, a pointer is a programming language datatype whose value refers directly to (points to) another value stored elsewhere in the computer memory using its address. ... In computing, a stack frame is a data structure used to create temporary storage for data and saved state in functions. ... Debugging is a methodical process of finding and reducing the number of bugs, or defects, in a computer program or a piece of electronic hardware thus making it behave as expected. ... Stack in computing refers to: Stack (data structure) Stack-based memory allocation as opposed to Heap-based memory allocation in computing architecture. ... The Motorola 680x0/0x0/m68k/68k/68K family of CISC microprocessor CPU chips were 32-bit from the start, and were the primary competition for the Intel x86 family of chips. ... An instruction set, or instruction set architecture (ISA), describes the aspects of a computer architecture visible to a programmer, including the native datatypes, instructions, registers, addressing modes, memory architecture, interrupt and exception handling, and external I/O (if any). ... Tux is the official Linux mascot. ...
