This article describes the calling conventions used when programming x86 architecture microprocessors. Calling conventions describe the interface of called code: The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated; How parameters are passed (pushed on the stack, placed in registers, or a mix ...
A common aspect of an ABI is the calling convention, which determines how data is provided as input to, or read as output from, computational routines. Examples of this are the x86 calling conventions. Adhering to an ABI (which may or may not be officially standardized) is usually the job of a compiler, operating system, or library author ...
The calling convention of a given program's language may differ from the calling convention of the underlying platform, OS, or of some library being linked to. For example, on 32-bit Windows, operating system calls have the stdcall calling convention, whereas many C programs that run there use the cdecl calling convention. To accommodate these ...
Under certain calling conventions it is the callee's responsibility to clean the arguments off the stack, so the epilogue can also include the step of moving the stack pointer down or up. For example, these three steps may be accomplished in 32-bit x86 assembly language by the following instructions:

MIPS (Microprocessor without Interlocked Pipelined Stages) [1] is a family of reduced instruction set computer (RISC) instruction set architectures (ISA) [2]: A-1 [3]: 19 developed by MIPS Computer Systems, now MIPS Technologies, based in the United States.
This problem is an act to force some variables to be assigned to particular registers. For example, in PowerPC calling conventions, parameters are commonly passed in R3-R10 and the return value is passed in R3. [12] NP-Problem Chaitin et al. showed that register allocation is an NP-complete problem.
When interfacing pieces of code with incompatible calling conventions, a trampoline is used to convert the caller's convention into the callee's convention. In embedded systems, trampolines are short snippets of code that start up other snippets of code. For example, rather than write interrupt handlers entirely in assembly language, another ...
