      Deprecate FLOAT-TRAPPING-NAN-P in favor of FLOAT-SIGNALING-NAN-P. · 9b6ad201
      Raymond Toy authored
      These numbers are called signaling, not trapping NaN in almost all
      usages.
      
       * code/exports.lisp:
         * Export FLOAT-SIGNALING-NAN-P.
       * code/float.lisp:
         * Implement FLOAT-SIGNALING-NAN-P.
         * Make FLOAT-TRAPPING-NAN-P an inline call to the
           FLOAT-SIGNALING-NAN-P and add a docstring to say it is
           deprecated. 
       * code/print.lisp:
         * Print "Signaling" instead of "Trapping".
       * i18n/locale/cmucl.pot:
         * Regenerated due to the changes in docstrings.

      Re-enable the x87 floating-point mode stuff. · 2c4a13af
      Raymond Toy authored
      On 32-bit linux, we can still get FP exceptions using x87 because
      32-bit linux can still use x87 instructions for arithmetic.  Because
      of this, we need to re-enable the support x87 floating-point modes,
      including getting and setting the modes and also extracting the modes
      from a sigcontext.
      
       * src/code/float-trap.lisp:
         * Put back support for getting and setting the x87 FP modes. 
       * src/compiler/x86/float.lisp:
         * Add comment on the layout of the status and control words for
           x87. 
       * src/lisp/Linux-os.c:
         * Put back support for getting the x87 (and sse2) FP modes. Needed
           in the sigfpe-handler in float-trap.lisp.
      
      Some of this needs to be cleaned up because we always require sse2
      now.

           and just compare that lisp streams and Gray streams produce the
           same output.

      Fix ticket:105 by not flaming out on a closed stream. · c0052f55
      Raymond Toy authored
       * code/reader.lisp:
         * The READER-ERROR condition tries to be helpful and print out the
           position of where the error occurred using FILE-POSITION. But
           FILE-POSITION flames out when the stream is closed, so check for
           a closed stream before calling FILE-POSITION
