+// History
+//==============================================================
+// 2/02/00  Initial revision
+// 6/28/00  Improved speed 
+// 6/31/00  Changed register allocation because of some duplicate macros
+//          moved nan exit bundle up to gain a cycle. 
+// 8/08/00  Improved speed by avoiding SIR flush.
+// 8/15/00  Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+// 8/17/00  Changed predicate register macro-usage to direct predicate
+//          names due to an assembler bug.
+// 10/17/00 Improved speed of x=0 and x=1 paths, set D flag if x denormal.
+
+// Description
+//=========================================
+// The asinf function computes the arc sine of x in the range [-pi,+pi].
+// A doman error occurs for arguments not in the range [-1,+1].
+// asinf(+-0) returns +-0
+// asinf(x) returns a Nan and raises the invalid exception for |x| >1 
+
+// The acosf function returns the arc cosine in the range [0, +pi] radians.
+// A doman error occurs for arguments not in the range [-1,+1].
+// acosf(1) returns +0
+// acosf(x) returns a Nan and raises the invalid exception for |x| >1
