      o Command line parsing now recognizes "--" and disables any further
        processing by CMUCL itself.  Everything after "--" is placed in the
        new variable EXT:*COMMAND-LINE-APPLICATION-ARGUMENTS*, which is a
        list of strings.
      
      code/exports.lisp:
      o Export EXT:*COMMAND-LINE-APPLICATION-ARGUMENTS*.
      
      general-info/release-19f.txt:

      Fix for handling arithmetic errors with x87. · 9edd3c4b
      rtoy authored
      Use bootstrap-2009-01-1.lisp to bootstrap this change.
      
      code/float-trap.lisp:
      o FLOATING-POINT-MODES for :X87 needs to massage the results into the
        expected format (SSE2 MXCSR order).
      o Update for changed VOP names too.
      
      compiler/x86/float.lisp:
      o Rename the floating-point-modes and set-floating-point-modes VOPS to
        x87-floating-point-modes and set-x87-floating-point-modes.  Change
        the translations accordingly too.
      
      compiler/x86/parms.lisp:
      o The float property bytes have been updated to match the SSE2 MXCSR
        register for both SSE2 and X87 builds because the code assumes SSE2
        format.
      
      lisp/Linux-os.c:
      o Don't OR in the SSE2 modes if we're not running an SSE2 build.
        Doing this can erroneously mask out exceptions because the Lisp code
        didn't set up the sse2 modes.  (This happens if you select the x87
        core on a chip that supports sse2.)
      
      lisp/globals.h:
      o Declare fpu_mode.
      
      lisp/lisp.c:
      o Set fpu_mode to be the mode determined from the core file.  Needed
        in Linux-os.c to process the SSE2 modes correctly with an x87 core
        on a sse2-capable chip.

      Oops. Need to move %DOUBLE-DOUBLE-FLOAT from compiler/float-tran.lisp · a45f0d42
      rtoy authored
      to code/float.lisp because we need this early in the build process to
      handle float types.
      
      This might cuase problems with bootstrapping double-double floats!

                        11.1111111111111107163651467999443w0)
                       (RATIONAL 1 100/9))>
      
      instead of
      
      #<UNION-TYPE (OR (SINGLE-FLOAT 1.0 11.111111)
                       (DOUBLE-FLOAT 1.0d0 11.11111111111111d0)
                       (DOUBLE-DOUBLE-FLOAT 1.0w0
                        11.1111111111111111111111111111111w0)
                       (RATIONAL 1 100/9))>
      
      The bound for double-double-float is not quite correct in the former
      result, and is correct in the latter.

      Change how we put the FPU type into the core file. We can't use · 29f1fd98

      compile-time options to do this.  The running core file has to tell
      us.
      
      lisp/save.c:
      o Add extra arg to save function to indicate whether the core we're
        saving supports sse2 or not.  Non-zero means sse2.
      o Put the correct indication into the core file.

      o Update declaration of save.
      
      code/save.lisp:

        support sse2 or not.

      Speed up bignum-truncate by getting rid of the special variables · b338119a
      rtoy authored
      *truncate-x* and *truncate-y*.  Accessing these in tight loops hurts
      performance.  So pass truncate-x and truncate-y as parameters to the
      routines that need them.  Reorder the truncate support routines so we
      can block-compile all of the routines for truncate.
      
      With these changes, we see the following changes according to
      cl-bench.  The first column and reference is 2008-10 snapshot
      (darwin), and the next column is the ratio of this new code to the
      reference.  So we see improvements from 10% to 50%.

      Ticket #24. · f169d3f0
      rtoy authored
      Take the rule of float precision contagion (CLHS 12.1.4.4) to also
      mean that the result should be as accurate as the most accurate
      argument.  Effectively, all args are coerced to the highest precision
      first before computing expt.
      
      There's a simple test program to check that every case is covered with
      the expected precision.  (I think).
      
      (defun test-expt ()
        (dolist (base '(2 2f0 2d0 2w0) t)
          (dolist (power '(1/2 .5f0 .5d0 .5w0))
            (flet ((test-it (b p a eps expected)
      	       (let* ((res (expt b p))
      		      (absdiff (abs (- res a))))
      		 (unless
      		     (or (typep (realpart res) (type-of expected))
      			 (<= absdiff (* 10 eps)))
      		   (format t "FAILED: ~A^~A = ~A (~A)~%" b p res a)))))
      
      	;; Compute base^power.
      	(let* ((expected-type
      		(let ((prod (* base power)))
      		  (if (rationalp prod)
      		      1f0
      		      prod)))
      	       (eps (etypecase expected-type
      		      ((or rational single-float)
      		       single-float-epsilon)
      		      (double-float
      		       double-float-epsilon)
      		      (double-double-float
      		       1w-31)))
      	       (answer (sqrt (float base expected-type))))
      	  (test-it base power answer eps expected-type)
      	  (test-it base (complex power) answer eps expected-type)
      	  (test-it (complex base) power answer eps expected-type)
