-// History
-//==============================================================
-// 02/02/00 Initial version
-// 03/20/00 Improved speed
-// 06/01/00 Fixed bug when x a double-extended denormal
-// 12/08/00 Corrected label on .endp
-// 01/23/02 Added handling for int 32 or 64 bits
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 02/10/03 Reordered header: .section, .global, .proc, .align
-//
-// API
-//==============================================================
-// double __libm_frexp(double x, int* y, int int_type)
-// input  floating point f8, pointer to y (r33), int int_type (r34)
-// output floating point f8, returns the fraction of x, 0.5 <= fraction < 1.0
-// output int* y, returns the true exponent of x
-//
-// int_type = 0 if int is 32 bits
-// int_type = 1 if int is 64 bits
-//
-// int* y is returned as a 32 bit integer if int_type = 0
-// int* y is returned as a 64 bit integer if int_type = 1
-//
-// Overview of operation
-//==============================================================
-// break a floating point x number into fraction and an exponent
-// The fraction is returned as a double
-// The exponent is returned as an integer pointed to by y
-//    This is a true (not a biased exponent) but 0fffe is subtracted
-//    as a bias instead of 0xffff. This is because the fraction returned
-//    is between 0.5 and 1.0, not the expected IEEE range.
-//
-// The fraction is 0.5 <= fraction < 1.0
-//
-// Registers used
-//==============================================================
-//
-// general registers: 
-// r14  exponent bias for x negative
-// r15  exponent bias for x positive
-// r16  signexp of x
-// r17  exponent mask
-// r18  exponent of x
-// r19  exponent result
-// r20  signexp of 2^64
-// r32  on input contains the 64-bit IEEE double that is in f8
-// r33  on input pointer to 32-bit or 64-bit integer for exponent
-// r34  on input contains 0 if output int is 32 bits, else output int is 64 bits
-//
-// predicate registers:
-// p6   set if x is Nan, zero, or infinity
-// p7   set if x negative
-// p8   set if x positive
-// p9   set if x double-extended denormal
-// p10  set if int_type = 0, 32-bit integer
-// p11  set if int_type = 1, 64-bit integer
-//
-// floating-point registers:
-// f8  input, output
-// f9  normalized x
-// f10 signexp for significand result for x positive
-// f11 signexp for significand result for x negative
-// f12 2^64
