(RTL) 1. A kind of hardware description language (HDL) used in describing the register s of a computer or digital electronic system, and the way in which data is transferred between them.
2. An intermediate code for a machine with an infinite number of register s, used for machine-independent optimisation. RTL was developed by Chris Fraser cwf@research.att.com and J. Davidson jwd@virginia.edu at the University of Arizona in the early 1980s. RTL is used by the GNU C compiler, gcc and by Davidson's VPCC (Very Portable C compiler).
