for the removal of this SC. There is a current limit of 32 SCs and with new features planned they are becoming a scarce resource; the dword-reg SC is redundant as the unsigned-reg etc SCs can be used for temporaries.

node-var as an optional argument so the allocation function can make policy decisions (to inline with GENCGC). Remove the make-complex-{single,double}-float functions, and just define the VOPs as translations of the complex function. Fix a few bugs in the complex-float move VOPs.

common binaries to be run on both: * The immediate-stack storage class has been removed, this is unnecessary as the descriptor-stack SC can be used. It may have once been part of some GC stragety to reduce the number of stack slots that needed to be noted for a GC. * The object allocation has been abstracted and cleaned up. This should produce slightly faster smaller code with CGC, and can be compiled to support inline allocation with GENCGC. CGC compiled code will run under GENCGC, and GENCGC binaries that don't use inline allocation will run under CGC. * A random hash is now placed in the unused symbol object slot (the symbol-hash slot). This saves flushing the info cache at each GC, and may have other uses for symbol based hash tables. Should help MP safety. * Common set of static symbols used by both CGC and GENCGC. * Corrections to the stack-ref VOP; now returns lisp objects not unsigned numbers. Required some patches to debug-int. * Inline unsigned/signed byte 32 to bignum allocation enabled. * Support for the x86 xadd instruction applied to instance slot and symbol values - may be handy for some MP code. * Bump up the FASL file version from 1 to 2.

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.

(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.
