-// History
-//==============================================================
-// 3/20/00: Initial version
-// 6/01/00: Fixed bug when x a double-extended denormal
-// 12/08/00 Corrected label on .endp
-//
-// API
-//==============================================================
-// long double frexpl(long double x, int* y)
-// long double __libm_frexp_4l(long double x, int* y)
-//   where int* y is a 32-bit integer
-//
-// Overview of operation
-//==============================================================
-// break a floating point x number into fraction and an exponent
-// The fraction is returned as a long 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
-// r32-33  on input contains the 80-bit IEEE long double that is in f8
-// r34  on input pointer to 32-bit integer for exponent
-//
-// 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
-//
-// 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
