Therefore, when the compiler is translating code to machine-language, it must decide how to allocate variables to the limited number of registers in the CPU. [ 2 ] [ 3 ] Not all variables are in use (or "live") at the same time, so, over the lifetime of a program, a given register may be used to hold different variables.
In computing, inline expansion, or inlining, is a manual or compiler optimization that replaces a function call site with the body of the called function. Inline expansion is similar to macro expansion, but occurs during compilation, without changing the source code (the text), while macro expansion occurs prior to compilation, and results in different text that is then processed by the compiler.
As of June, 2011, PSL remains the source code language for the FIS Profile banking system, deployed in 26 countries and over 200 institutions, including some of the world’s largest banks. While Java and commercial RDMS deployments are possible in the future, today 100% of the deployments are on the GT.M MUMPS target language and database ...
In computing, code generation is part of the process chain of a compiler, in which an intermediate representation of source code is converted into a form (e.g., machine code) that can be readily executed by the target system. Sophisticated compilers typically perform multiple passes over various intermediate forms.
Whereas the singleton allows only one instance of a class to be created, the multiton pattern allows for the controlled creation of multiple instances, which it manages through the use of a map. Rather than having a single instance per application (e.g. the java.lang.Runtime object in the Java programming language ) the multiton pattern instead ...
Although the technique originated in Smalltalk, [1] the best-known language that uses this technique is Java. Since the machine code emitted by a dynamic compiler is constructed and optimized at program runtime, the use of dynamic compilation enables optimizations for efficiency not available to statically-compiled programs (i.e. those compiled ...
This optimization may include inlining code. Examples of adaptive optimization include HotSpot and HP's Dynamo system. [1] In some systems, notably the Java Virtual Machine [citation needed], execution over a range of bytecode instructions can be provably reversed. This allows an adaptive optimizer to make risky assumptions about the code.
When Java source code is compiled, annotations can be processed by compiler plug-ins called annotation processors. Processors can produce informational messages or create additional Java source files or resources, which in turn may be compiled and processed. However, annotation processors cannot modify the annotated code itself.
