;; If you want all core functions to be inline (like the C++ code
;; does), add :qd-inline to *features* by enabling the following line.
;; This makes compilation much, much slower, but the resulting code
;; conses much less and is significantly faster.

;; To be able to inline all the functions, we need to make
;; *inline-expansion-limit* much larger.
;;
;; Not sure we really want to inline everything, but the QD C++ code
;; inlines all of the functions so we do the same. This makes CMUCL
;; take a very long time to compile the code, and the resulting
;; functions are huge. (I think div-qd is 8 KB, and sqrt-qd is a
;; whopping 30 KB!)

;; For all Lisps other than CMUCL, oct uses arrays to store the
;; quad-double values. This is denoted by the feature :oct-array.
;; For CMUCL, quad-doubles can be stored in a (complex
;; double-double-float) object, which is an extension in CMUCL.
;; If you want CMUCL to use an array too, add :oct-array to *features*.
