find-applicable-methods expects to be called with symbols:

(ccl::FIND-APPLICABLE-METHODS 'PROCESS-KILL '(PROCESS) nil) -> (#<CCL::STANDARD-KERNEL-METHOD PROCESS-KILL (PROCESS)>)

but "some" functions pass a list of actual classes as the args parameter, like swank-backend::xref-locations so i can't use "who calls".

my workaround is to map the args list and replace non-symbols by the class-name like this:

(defun find-applicable-methods (name args qualifiers)
  (setf args
	(mapcar #'(lambda (arg)
		    (if (symbolp arg)
			arg
			(class-name arg)))
		args))
  ...)

you can trigger the error without slime with xref-describe:

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.

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.
