+// History
+//==============================================================
+// 02/03/00 Initial version
+// 05/26/00 Fix bug when x a double-extended denormal;
+// if x=0 call error routine, per C9X
+// 08/15/00 Bundle added after call to __libm_error_support to properly
+// set [the previously overwritten] GR_Parameter_RESULT.
+// 01/20/01 Fixed result for x=0
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 01/20/03 Improved performance

+// API
+//==============================================================
+// int ilogbl( long double x );
+//
+// Overview of operation
+//==============================================================
+// The ilogbl function extracts the exponent of x as an integer
+// and returns it in r8
+//
+// ilogbl is similar to logbl but differs in the following ways:
+// +-inf
+// ilogbl: returns INT_MAX
+// logbl: returns +inf
+// Nan returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
+// ilogbl: returns INT_MAX (7fffffff)
+// logbl: returns QNAN (quietized SNAN)
+// 0 returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
+// ilogbl: returns -INT_MAX (80000001)
+// logbl: returns -inf, raises the divide-by-zero exception,
+// and calls libm_error_support to set domain error
+//
+// Registers used
+//==============================================================
+// general registers used:
+// r26 -> r39
+// r36 -> r39 used as parameters to error path
+//
