Extended Tiny
A research/educational tool for experimenting with array
data dependence tests and reordering transformations. It
works with a language tiny, which does not have procedures,
goto's, pointers, or other features that complicate
dependence testing.
Michael Wolfe's original tiny has been extended
substantially by William Pugh <pugh@cs.umd.edu> et al. at the
University of Maryland.
Version 3.0 (Dec 12th, 1992) includes a programming
environment, dependence tester, tests translator
(Fortran->tiny), documentation, and technical reports. It
should run on any Unix system.
