	WIL: A Compiler Intermediate Language with Explicit Support for Representations
		WIL is a textual compiler intermediate language designed primarily for object-oriented languages, to be used in the Whirlwind compiler being developed at the University of Washington.
		This representation can be either partially or fully abstract, which allows the ability to defer decisions about the concrete bit layout of some or all of the value’s contents to later stages of compilation.
		Representations for generic Objects and 2Dpoints are named, and each value in the program is annotated with a representation.

	Intermediate Depth Representations
		This paper focuses on the computational and representational advantages that may exist in using representations whose depth is intermediate, trading off the advantages and disadvantages of shallow and deep representations.
		If intermediates use deep pathophysiological models in preference to the compiled surface knowledge used by experts, they will perform well when given time to recall cases, since their representation is richer.
		Thus the type of representation which performs best varies with task, and with the intermediate effect, subjects with different levels of expertise are hypothesised to have preferential access to different depths of representation.

	Register Transfer Language - Wikipedia, the free encyclopedia
		Register Transfer Language (RTL) is an intermediate representation used by the GCC compiler.
		RTL is used to represent the code being generated, in a form closer to assembly language than to the high level languages which GCC compiles.
		RTL is generated from the GCC Abstract Syntax Tree representation, transformed by various passes in the GCC 'middle-end', and then converted to assembly language.

	Front-End
		The Intermediate Representation is given in terms of a simple intermediate language comprised of IR-operations and Send/Receive communication primitives.
		For instance, the following piece of C-code generates the Intermediate Representation for our example and can be used as the first part of a FAST simulator for this toy application.
		In the second phase of the front-end a simple parser transforms the Intermediate Representation into a weighted task-flow graph which follows the Macro-Dataflow model of computation [8].

	Textbook Methods of Parsing in COBOL
		A typical compiler may be divided into three components: the front end, the intermediate representation, and the back end.
		The intermediate representation is a complex data structure which embodies the meaning and intent of the source code.
		Stripped of all aspects of mere physicality, the intermediate representation is a pristine abstraction, shimmering unseen in iridescent groves of silicon.

	Descriptional Composition of Compiler Components
		Suppose one uses an intermediate representation and divides up the compiler into two parts, one which compiles the source to the intermediate representation and another which translates a program in the intermediate representation to the target machine language.
		Doing so may make the compiler easier to understand, and furthermore, a well-chosen intermediate representation may prove a suitable target for other source languages, or a suitable source for translating to other machines.
		The back-end of the Oberon2 compiler consists of a translation to a form of the ``GCC tree'' intermediate representation.

	1.5.2 Intermediate Representation (Site not responding. Last check: 2007-09-17)
		Intermediate representation, sometimes called Intermediate Language (IL) or Intermediate Code (IC), is an alternative form to a parse tree.
		Sometimes the parser creates this intermediate form directly; sometimes the parse tree is converted.
		It removes some of the intermediate categories and captures the elementary structure.

		This representation is then typically processed by a code-generator in order to produce machine code, but could also be used in the creation of source browsers, intelligent editors, automatic documentation generators, interpreters, and any other programs needing the ability to process C or C++ code.
		In particular, it documents the internal representation for C and C++ source constructs, and the macros, functions, and variables that can be used to access these constructs.
		The C++ representation is largely a superset of the representation used in the C front end.

		Also with " correct programming languages " one proceeds frequently in such a way that one produces first the source program (the " concrete syntax") translated into an internal intermediate representation ("abstract syntax") and then from this intermediate representation the target program.
		This internal representation is called frequently also intermediate representation, because from their the late required output one produces (see in addition the example after the next ahnen_v5.g.

	Intermediate Representation
		If contextual analysis is a separate pass, then the AST is explicitly constructed and a decorated abstract syntax tree may be used as the intermediate representation.
		While it is not difficult to add a code generation module to the front end, an intermediate representation that facilitates additional processing and can take one of several forms
		An intermediate representation (IR) is a kind of abstract machine language that can express the target-machine operations without committing to too much machine-specific detail, but independent of the details of the source language.

	An Intermediate Level Representation Scheme for Secondary Features Recognition and B-rep Model Simplification (Site not responding. Last check: 2007-09-17)
		Another drawback which hinders the correct engineering evaluation of a part is that its geometrical and topological representation is not unique, since it depends either on the different procedures used to generate CAD models or on the different internal representation of the geometric kernels used by CAD packages.
		The overall aim of this work is to define an intermediate representation scheme which incorporates information about minor features such as chamfers, fillets, rounds and grooves into a graph based representation and overcomes the problem of non-uniqueness in the geometric representation.
		The representation scheme discussed here takes as input a solid model in B-rep form, and provides a description of a part at an higher level of abstraction in comparison with the raw B-rep description.

		Convert given intermediate representation back into supported language's source code.
		Actually, this will usually not happen because intermediate representation will not remember all semantic details of the original code text and result may be slightly different, though the result code will be semantically equivalent to the input.
		It is actually possible to write plug-in that will actually compile the intermediate code representation into assembly listing or binary object image for specific platform and CPU.

	FlatCurry
		The translation table describes the mapping of identifiers (type constructors, data constructors, defined functions) used in the source program into their corresponding internal names used in the intermediate FlatCurry program (since it is often necessary to rename identifiers to avoid name clashes, e.g., the internal names are prefixed by the module name).
		This information might be used by back ends for representing intermediate (e.g., during debugging) or final results or to allow the user to type in and evaluate arbitrary expressions.
		This representation has been used in a number of tools written in Curry, e.g., a graphical programming environment for Curry (CIDER) or a partial evaluator for Curry programs.
