Contained within the PSW are the two bit condition code, representing zero, positive, negative, overflow, and similar flags of other architectures' status registers. Conditional branch instructions test this encoded as a four bit value, with each bit representing a test of one of the four condition code values, 2 3 + 2 2 + 2 1 + 2 0. (Since IBM ...
A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.
Version 4, 1 March 2006 Although individual manufacturers have their own particular requirements, the Automotive Industry Action Group (AIAG) has developed a common PPAP standard as part of the Advanced Product Quality Planning (APQP) [ 1 ] – and encourages the use of common terminology and standard forms to document project status.
The processor stores the PSW, with an interruption code inserted, into the old PSW location and then loads the PSW from the new PSW location. This generally replaces the instruction address, thereby effecting a branch, and (optionally) sets and/or resets other fields within the PSW, thereby effecting a mode change.
Conditional move instructions write the contents of one register over another only if the predicate's value is true, whereas conditional select instructions choose which of two registers has its contents written to a third based on the predicate's value. A more generalized and capable form is full predication. Full predication has a set of ...
The following computer algebra systems and software packages use some version of the Baillie–PSW primality test. Maple 's isprime function, [ 12 ] Mathematica 's PrimeQ function (that already uses 2020's version of Baillie–PSW), [ 13 ] PARI/GP 's isprime and ispseudoprime functions, [ 14 ] and SageMath 's is_pseudoprime function [ 15 ] all ...

In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a type of intermediate representation (IR) where each variable is assigned exactly once. SSA is used in most high-quality optimizing compilers for imperative languages, including LLVM , the GNU Compiler Collection , and many commercial compilers.
