+// History
+//==============================================================
+// 2/02/00  Initial version 
+// 8/17/00  New and much faster algorithm.
+// 8/30/00  Avoided bank conflicts on loads, shortened |x|=1 and x=0 paths,
+//          fixed mfb split issue stalls.
+
+// Description
+//=========================================
+// The acos function computes the principle value of the arc sine of x.
+// A doman error occurs for arguments not in the range [-1,+1].
+
+// The acos function returns the arc cosine in the range [0, +pi] radians.
+// acos(1) returns +0, acos(-1) returns pi, acos(0) returns pi/2.
+// acos(x) returns a Nan and raises the invalid exception for |x| >1
+
+// The acos function is just like asin except that pi/2 is added at the end.
+
+//
+// Assembly macros
