+        ;; ABI considerations for the divide functions
+        ;; The following registers are call-used:
+        ;; __c6xabi_divi A0,A1,A2,A4,A6,B0,B1,B2,B4,B5
+        ;; __c6xabi_divu A0,A1,A2,A4,A6,B0,B1,B2,B4
+        ;; __c6xabi_remi A1,A2,A4,A5,A6,B0,B1,B2,B4
+        ;; __c6xabi_remu A1,A4,A5,A7,B0,B1,B2,B4
+        ;;
+        ;; In our implementation, divu and remu are leaf functions,
+        ;; while both divi and remi call into divu.
+        ;; A0 is not clobbered by any of the functions.
+        ;; divu does not clobber B2 either, which is taken advantage of
+        ;; in remi.
+        ;; divi uses B5 to hold the original return address during
+        ;; the call to divu.
+        ;; remi uses B2 and A5 to hold the input values during the
+        ;; call to divu.  It stores B3 in on the stack.
