Example of branch table in Wikibooks for IBM S/360; Examples of, and arguments for, Jump Tables via Function Pointer Arrays in C/C++; Example code generated by 'Switch/Case' branch table in C, versus IF/ELSE. Example code generated for array indexing if structure size is divisible by powers of 2 or otherwise.
[a] Branch (or branching, branched) may also refer to the act of switching execution to a different instruction sequence as a result of executing a branch instruction. Branch instructions are used to implement control flow in program loops and conditionals (i.e., executing a particular sequence of instructions only if certain conditions are ...
Based upon this definition of dominance, node N 1 c-commands node N 2 if and only if: Node N 1 does not dominate N 2, N 2 does not dominate N 1, and; The first (i.e. lowest) branching node that dominates N 1 also dominates N 2. [2] For example, according to the standard definition, in the tree at the right,
Multiway branch is the change to a program's control flow based upon a value matching a selected criteria. It is a form of conditional statement . A multiway branch is often the most efficient method of passing control to one of a set of program labels , especially if an index has been created beforehand from the raw data .
An indirect branch (also known as a computed jump, indirect jump and register-indirect jump) is a type of program control instruction present in some machine language instruction sets. Rather than specifying the address of the next instruction to execute , as in a direct branch , the argument specifies where the address is located.
Branch predictors play a critical role in achieving high performance in many modern pipelined microprocessor architectures. Figure 1: Example of 4-stage pipeline. The colored boxes represent instructions independent of each other. Two-way branching is usually implemented with a conditional jump instruction. A conditional jump can either be ...
Computation tree logic (CTL) is a branching-time logic, meaning that its model of time is a tree-like structure in which the future is not determined; there are different paths in the future, any one of which might be an actual path that is realized.
A number of languages implement a form of switch statement in exception handling, where if an exception is raised in a block, a separate branch is chosen, depending on the exception. In some cases a default branch, if no exception is raised, is also present. An early example is Modula-3, which use the TRY...
