#888 invalid format can produce 0+3 Arthur Cater
Description

In latest trunk, and afaik all earlier versions too, (format nil "~3,'0@D" 3) produces "0+3" - not "+03" as I'd expect.

#1000 fixed floating-point callbacks and ARM hard-float conventions Gary Byers
Description

DEFCALLBACK expands into code which unconditionally assumes that the ARM soft-float ABI is in effect, so callbacks which accept floating-point arguments or return floating-point results won't work correctly if the hard-float ABI is in use.

DEFCALLBACK should generate code which works under either ABI, as long as the older soft-float ABI is in widespread use.

#804 fixed fixnum->double vinsn broken on ARM Ivan Shvedunov
Description

Compilation of the following function fails on ARM: 

(defun fixnum-double (x)
  (declare (fixnum x))
  (* x 10d0))

That's because it uses FIXNUM->DOUBLE vinsn that has :single-float temp which is not supported by CCL::ALLOCATE-TEMPORARY-VREG.
