      ANSI CL says LOAD takes an :external-format keyword to specify the
      format of the file or stream being loaded.  CMUCL already had the
      :contents keyword that does this, but its default was nil instead of
      :default.
      
      The appended patch replaces :contents with :external-format.  This
      will break any code that uses :contents.

      Replace :contents option to LOAD with :external-format, for ANSI CL
      conformance.

      This revision merges in many of the fixes for ANSI condition types · 42efe00d
      pw authored
      in various calls to ERROR. Those easily handled by using new condition
      types simple-file-error and simple-program-error are included.
      
      The only functional change here is that the function CHARACTER no longer
      accepts an integer argument so as to be ANSI compliant. This may
      break some code.

      Gray streams support: · 6c21ff8a
      dtc authored
      * Rename the 'stream structure class to sys:lisp-stream.
      * Add a new none hierarchical 'stream built-in class which inherits
        from: instance, t.
      * Hack in the new stream class as a mixin for the structure base
        lisp-stream class which now inherits from: stream, structure-object,
        instance, t.
      * Add a new 'fundamental-stream standard-class which includes 'stream
        as a mixin, and add PCL hacks to allow this to be redefined after PCL is
        loaded to be (defclass fundamental-stream (standard-object stream) ...).
      * Add appropriate support to the base stream functions to dispatch to
        the Gray stream functions for the handling of fundamental-streams.
        Some of the lisp-streams encapsulating CLOS streams still need
        a little work.

      Improved support for (complex single-float) and (complex double-float) · 4c3b1bb6
      dtc authored
      types. Adds storage classes to the backend for these so they can be
      stored in registers or on the stack without consing; new primitive
      types etc. Also adds (simple-array (complex {single,double}-float))
      array types to avoid consing and speed vectors operations.  All
      these changes are conditional on the :complex-float feature. More work
      is needed to exploit these changes: improving the type dispatch in the
      various function; maybe compiler transforms or more VOPs to handle
      common functions inline.

      I just finished making load-foreign work on SGIs, along with fixing calling of · efd9aa3b
      pw authored
      foreign functions taking floating-point arguments after integer arguments but
      before the fourth argument (more or less; mips has unusual C calling
      conventions), and making cmucl work on IRIX 6.2 on the Onyx (where the system
      page size has changed). I've included the patches below, along with some
      discussion of the changes and a couple of problems with cmucl's interaction with
      dynamic loading. Also, there's a misc change to make ioctls work (I'm not sure
      for what version the released code worked, but it doesn't work on anything I
      have). The patches do not fix the R10000; cmucl continues to not work on it (O2
      and Octane).
      
      The fixes make cmucl on the sgi use shared libraries so it can use dlopen et al
      in load-foreign; this is based on the solaris implementation. The problem with
      this is that the addresses of foreign variables are included directly in the
      dumped lisp image (without relocation on loading), which might result in a
      problem if cmucl is run with newer shared libraries than those it was compiled
      and dumped with. As far as I can tell, for the SGI at least, this does not
      affect function calls because the addresses used (and included in the dumped
      image) are those of stub routines that jump to the actual routines, thus are
      located in the executable proper rather than in the shared libraries, and so
      shouldn't be changed by a new version of the shared library.
      
      Unfortunately, this is not the case for global variables. Fortunately, there
      appear to only be two foreign variables used by cmucl in any of its system code
      winding up in the dumped image: errno and tzname. Apparently, Solaris relocates
      data references in dsos to match the program, while IRIX relocates data
      references in the program to match the dso. Thus, on Solaris, you don't need to
      do anything special for cmucl to work with a newer runtime libc, but on IRIX it
      gets the wrong value of errno and tzname. Unfortunately, the address of errno is
      different between irix 6.2, 6.3, and 6.4 (all of which we have to have because
      SGI doesn't have a single cross-platform OS version yet), which would require a
      different lisp.core for each machine (you just need to run mk-lisp, not
      recompile) if it weren't for the hack below. But fortunately again, a lisp
      compiled for one version seems to be able to run on another version well enough
      to generate the new lisp.core (presumably the worst that would happen is that
      error messages could be confusing). It would be really nice to avoid this
      problem. Perhaps some kind of relocation table could be added to the dumped
      image format? I don't know enough about the system to know how possible or
      ridiculous that suggestion is, unfortunately. Is the Solaris behavior guaranteed
      to be the same in future releases? If not, or if any other platforms have the
      irix behavior, this might become a more general problem. In the meantime, we use
      a hack: we *define* errno in undefineds.c rather than just referencing it; this
      results in warnings from the linker, but it resolves the conflict in favor of
      the definition in the program, relocating libc to match, thus fixing this
      problem for errno. The other global variables, tzname et al, can't be fixed this
      way as easily because they're listed as weak symbols, essentially aliases for
      the real symbol, so redefining them wouldn't cause libc to reference the new
      version. Thus, as long as you don't use tzname, there's no problem right now
      (although there may be if any other library global variables are used in cmucl
      in the future). The definition of tzname is in a progn preceeded by a comment
      which says not to use it, so hopefully it's not in fact used and therefore not a
      problem.
      
      
      These patches have been tested on an R5000 O2 running irix 6.3 and a dual R4400
      Onyx running irix 6.2. A previous version of these patches (for 17f) was tested
      on the onyx when it was running 5.3 (I think, maybe 5.2). The patches here are
      from the main branch of the CVS tar as of August 13. Incidentally, it was quite
      painful figuring out how to compile and bootstrap the current sources under the
      distributed irix 18a binary, even without trying :new-random or :signed-array
      (which I haven't tried to do yet); it might be nice to put a newer binary up...

      Support for some specialised signed array types: (signed-byte 8), · d5d4504f
      dtc authored
      (signed-byte 16), (signed-byte 30), (signed-byte 32).  These patches
      include the general support and the x86 backend support; more to
      follow. The important changes are conditional on the :signed-array
      feature so shouldn't affect the source without this feature. This work
      has been driven by Raymond Toy.
