+// History
+//==============================================================
+// 2/02/00  Initial version
+// 2/16/00  Modified to conform to C9X 
+// 3/16/00  Improved speed
+// 4/04/00  Unwind support added
+// 5/30/00  Fixed bug when x double-extended denormal
+// 8/15/00  Bundle added after call to __libm_error_support to properly
+//          set [the previously overwritten] GR_Parameter_RESULT.
+//
+// API
+//==============================================================
+// double logb( double x);
+//
+// Overview of operation
+//==============================================================
+// The logb function extracts the exponent of x as an integer in 
+// floating-point format. 
+// logb computes log2 of x as a double
+//
+// logb is similar to ilogb but differs in the  following ways:
+//         +-inf
+//            ilogb: returns INT_MAX
+//             logb: returns +inf
+//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+//            ilogb: returns INT_MAX (7fffffff)
+//             logb: returns QNAN (quietized SNAN)
+//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+//            ilogb: returns -INT_MAX (80000001)
+//             logb: returns -inf, raises the divide-by-zero exception,
+//                   and calls libm_error_support to set domain error
+//
+// Registers used
+//==============================================================
+// general registers used: 
+// ar.pfs r32 
+// r33 -> r37
+// r38 -> r41 used as parameters to error path
+//
+// predicate registers used: 
+// p6, p7, p8
+// floating-point registers used: 
+// f9, f10, f11
+// f8, input
