      Revert changes to atanh · 6ed52aa0
      Raymond Toy authored
      Still need the special case for real args to get the right branch
      cuts.  Haven't yet figured out why the current code doesn't work when
      the arg is a pure real.  Soemthing to do with computing y, but not
      sure how to get that to work out without doing just explicitly
      checking for real args.  In that case, it's just much easier to change
      the arg to have the correct imaginary component to make it continuous
      with the desired quadrant.

      Derive the values on the branch cuts for acosh · 00d0cb6f
      Raymond Toy authored
      Conclusion: on the branch cuts, acosh is continuous with quadrant I
      for 9 <= x < 1 and with quadrant II for x < -1.  This, of course, is
      consistent with Kahan's coutner-clowkwise continuity principla.

      Add derivation for the values on the branch cut for acos · 53cf274f
      Raymond Toy authored
      We derive formulas for the values of acos(x) for x > 1 and x < -1 and
      show that for x > 1, acos is continuous with quadrant IV and for x <
      -1, acos is continuous with quadrant II.
      
      This matches Kahan's counter-clockwise countinuity for values on the
      branch cuts.

      Add utilities by Eric Marsden to contribs · 84fd9509
      Raymond Toy authored
      Eric Marsden wrote some useful utilities long ago.  Let's add them to
      the contrib directory so that we have our own copy of them instead of
      depending on emarsden.chez.com/downloads.
      
      We're adding:
      * cpc - CPU Performance Counters for Solaris
      * ssl-cmucl - interface to SSL streams
      * tcp-forwarder - TCP forwarder to redirect TCP connections to another
        port on another machine
      * xml-rpc - Port of Chris Double's xml-rpc client to Cmucl

      Clean up for fedora shell runner · 04d5d03f
      Raymond Toy authored
      We're not using the fedora docker anymore (because I can't get it to
      work anymore and don't remember how I got it to work to begin with).
      Thus, use the fedora shell executor to run CI so we don't need the
      image or to wget lots of stuff because it's already installed.
