    csrhodes authored
    	Fix bug 285
    	... %MULTIPLY vop was feeling free to scribble over its inputs
    	... add :FROM and :TO clauses to try to prevent this
    	... %MULTIPLY-AND-ADD vops are unchanged, but could quite easily be
    		wrong
    	OK, OK, I give in
    	... relax the type declaration on signed-immediate instructions
    		to allow (unsigned-byte 16)s through

    	"Oops"

    		consume all available CPU and RAM...
    	... unbreak the new vectorized transform by returning the
    		sequence argument rather than NIL.

    	No functional changes
    	... update the PPC instruction descriptions to mostly describe
    		their constraints (probably missing some :writes :lr)
    	... don't turn the scheduler on, though, because the assembler
    		wants to fill unschedulable areas with NOPs, which is
    		probably not a win

    ... major code shifting: simple-streams.lisp is no more; its contents
        have moved into several  files, each for a specific kind of stream
    ... file layout is now the same as cmucl pcl/simple-streams directory
        for easier trading of fixes / functionality
    ... new functionality: external formats (need some work still, but
        infractructure is there), string-streams
    ... Some functionality still missing (see TODO file)

    	Confirming what we already knew, part LXXVI

    	... so fix the operand to ADDIS in %SINGLE-FLOAT/SIGNED sufficiently
    		to allow the compiler to compile

    	Fix the ASH issues on x86.
    	... it seemed to me crying out for a CMOV optimization along the
    		lines of the sparc case, but to my dismay it seems that
    		x86's conditional move instruction does not allow
    		immediate arguments.  Maybe some bright young spark
    		nevertheless has a neat way of using modern instructions
    		to save a branch or two?

    	Exciting gencgc hacking: SB-SYS:WITH-PINNED-OBJECTS
    
    	When passing Lisp objects to foreign code, it is important
    	that GC doesn't change the object's address as the foreign
    	code's pointers to it won't be updated.  Traditionally this is
    	done using WITHOUT-GCING, but that's not ideal in a threaded
    	system where one thread may be doing a blocking alien call and
    	other threads would like to continue as normal.
    
    	So, instead we shove pointers to the important objects on the
    	C stack where they will cause the pages pointed to to be
    	pinned in place using preserve_pointers.  Additionally we make
    	a small change to gencgc to ensure that they _stay_ pinned in
    	subsequent GCs
    
    	On ports that use cheneygc we can't do this, so
    	WITH-PINNED-OBJECTS is just an alias for WITHOUT-GCING.  As
    	these ports don't have threads anyway, that's not a major
    	inconvenience.
    
    	Small updates to doc/internals-notes/threading-specials,
    	slightly larger updates to comments regarding ALLOCATION
    	and PSEUDO-ATOMIC macros
    
    	Documentation update to the FFI chapter

    	... tighten up the type of RANDOM;
    	... textual frobs around RANDOM area.
