For those who are interested in fortran on the Mac II under A/UX: We received our copy of the Green Hills f77 compiler last week (having had some difficulty applying the A/UX distribution f77 for our purposes 8=). This software is distributed by UniSoft under the somewhat funky name "Optimizing Fortran" (make sure to ask your vendor for the full name). We've found exactly one bug so far, which was extremely minor and easily worked around. Other than that the thing compiles *fast* (it appears to compile directly from source code to object code), and produces *very* tight code. For example, intrinsic floating point functions are substituted whenever possible with direct floating point coprocessor traps. Other [possible] optimizations include stack frame adjustment coalescing, register replacement of local variables by coloring, loop invariant analysis, etc. The manual is highly detailed, well written, and to the point. I'd rate the software 9.5 out of 10.0 (-0.5 for no index with the manual). ---------------------------------------------------------------------------- Carrick Talmadge | DISCLAIMER: C.T. has no association with clt@newton.physics.purdue.edu | either Green Hills or Unisoft.
