Greetings! Is there a reason that maxima instructs GCL alone to use
denormalized numbers in the f2cl stuff?
(defun d1mach (i)
(ecase i
(1
#-gcl least-positive-normalized-double-float
#+gcl least-positive-double-float)
(2 most-positive-double-float)
(3 double-float-epsilon)
(4 (scale-float double-float-epsilon 1))
(5 (log (float (float-radix 1d0) 1d0) 10d0))))
This will force -mieee-with-inexact on the alpha architecture, which
slows the code considerably.
Take care,
