-// History
-//==============================================================
-// 02/02/00 Initial version

-// 04/04/00 Unwind support added
-// 05/30/00 Fixed bug when x double-extended denormal
-// 08/15/00 Bundle added after call to __libm_error_support to properly
-//          set [the previously overwritten] GR_Parameter_RESULT.
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 01/20/03 Improved performance
-//
-// API
-//==============================================================
-// float logbf( float x );
-//
-// Overview of operation
-//==============================================================
-// The logbf function extracts the exponent of x as an integer in
-// floating-point format.
-// logbf computes log2 of x as a float
-//
-// logbf is similar to ilogbf but differs in the following ways:
-//         +-inf
-//            ilogbf: returns INT_MAX
-//             logbf: returns +inf
-//         Nan  returns FP_LOGBNAN (which is either INT_MAX or INT_MIN)
-//            ilogbf: returns INT_MAX (7fffffff)
-//             logbf: returns QNAN (quietized SNAN)
-//         0    returns FP_ILOGB0 (which is either INT_MIN or -INT_MAX)
-//            ilogbf: returns -INT_MAX (80000001)
-//             logbf: returns -inf, raises the divide-by-zero exception,
-//                   and calls libm_error_support to set domain error
-//
-// Registers used
-//==============================================================
-// general registers used:
-// r26 -> r38
-// r35 -> r38 used as parameters to error path
-//
-// predicate registers used:
-// p6, p7, p8
-// floating-point registers used:
-// f9, f10, f11
-// f8, input
