Update.

1998-02-13 17:39  Ulrich Drepper  <drepper@cygnus.com>

	* elf/Makefile: Don't use --version-script parameter to link ld.so
	unconditionally.

1998-01-02 04:19  Geoff Keating  <geoffk@ozemail.com.au>

	* math/Makefile: Add t_exp.
	* math/libm-test.c: Tighten accuracy bounds for exp(), correct
	constants.
	* math/test-reduce.c: Remove temporarily, it seems to be broken.
	* sysdeps/libm-ieee754/e_exp.c: Use accurate table method.
	* sysdeps/libm-ieee754/e_expf.c: Use table & double precision for
	better accuracy.
	* sysdeps/libm-ieee754/s_exp2.c: Use better polynomial; correct
	algorithm for very large/very small arguments.
	* sysdeps/libm-ieee754/s_exp2f.c: Use slightly better polynomial;
	correct algorithm for very large/very small arguments; adjust for
	new table.
	* sysdeps/libm-ieee754/t_exp.c: New file.
	* sysdeps/libm-ieee754/t_exp2f.h: Use table with smaller deltas.

	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Put 'strange test'
	back, with comment that explains what breaks when you remove it :-(.

	* localedata/xfrm-test.c: Avoid integer overflow.

	* stdlib/strfmon.c: char is unsigned, sometimes.

	*sysdeps/powerpc
	* sysdeps/powerpc/Makefile: Remove quad float support.
	* sysdeps/powerpc/q_*.c: Remove, they will become an add-on.
	* sysdeps/powerpc/quad_float.h: Likewise.
	* sysdeps/powerpc/test-arith.c: Likewise.

	(_ISwbit) [__BYTE_ORDER == __LITTLE_ENDIAN]: Correctly transform
	bit number.  This fixes the real bug and restores the integrity of

1998-02-12  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* stdio-common/vfscanf.c: Never try to read another character
	after EOF.  Don't decrement read_in after EOF, it wasn't
	incremented in the first place.
	(NEXT_WIDE_CHAR): Set First, not first.

1998-02-06 07:48  H.J. Lu  <hjl@gnu.org>

	* db/Makefile ($(inst_libdir)/libndbm.a,

-/* __ieee754_exp(x)
- * Returns the exponential of x.
- *
- * Method
- *   1. Argument reduction:
- *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2.  
- *
- *      Here r will be represented as r = hi-lo for better 
- *	accuracy.
- *
- *   2. Approximation of exp(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Write
- *	    R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
- *      We use a special Reme algorithm on [0,0.34658] to generate 
- * 	a polynomial of degree 5 to approximate R. The maximum error 
- *	of this polynomial approximation is bounded by 2**-59. In
- *	other words,
- *	    R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
- *  	(where z=r*r, and the values of P1 to P5 are listed below)
- *	and
- *	    |                  5          |     -59
- *	    | 2.0+P1*z+...+P5*z   -  R(z) | <= 2 
- *	    |                             |
- *	The computation of exp(r) thus becomes
- *                             2*r
- *		exp(r) = 1 + -------
- *		              R - r
- *                                 r*R1(r)	
- *		       = 1 + r + ----------- (for better accuracy)
- *		                  2 - R1(r)
- *	where
- *			         2       4             10
- *		R1(r) = r - (P1*r  + P2*r  + ... + P5*r   ).
- *	
- *   3. Scale back to obtain exp(x):
- *	From step 1, we have
- *	   exp(x) = 2^k * exp(r)
- *
- * Special cases:
- *	exp(INF) is INF, exp(NaN) is NaN;
- *	exp(-INF) is 0, and
- *	for finite argument, only exp(0)=1 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double 
- *	    if x >  7.09782712893383973096e+02 then exp(x) overflow
- *	    if x < -7.45133219101941108420e+02 then exp(x) underflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

+/* How this works:
+   The basic design here is from
+   Shmuel Gal and Boris Bachelis, "An Accurate Elementary Mathematical
+   Library for the IEEE Floating Point Standard", ACM Trans. Math. Soft.,
+   17 (1), March 1991, pp. 26-45.
+
+   The input value, x, is written as
+
+   x = n * ln(2)_0 + t/512 + delta[t] + x + n * ln(2)_1
+
+   where:
+   - n is an integer, 1024 >= n >= -1075;
+   - ln(2)_0 is the first 43 bits of ln(2), and ln(2)_1 is the remainder, so
+     that |ln(2)_1| < 2^-32;
+   - t is an integer, 177 >= t >= -177
+   - delta is based on a table entry, delta[t] < 2^-28
+   - x is whatever is left, |x| < 2^-10
+
+   Then e^x is approximated as
+
+   e^x = 2^n_1 ( 2^n_0 e^(t/512 + delta[t])
+               + ( 2^n_0 e^(t/512 + delta[t])
+                   * ( p(x + n * ln(2)_1)
+                       - n*ln(2)_1
+                       - n*ln(2)_1 * p(x + n * ln(2)_1) ) ) )
+
+   where
+   - p(x) is a polynomial approximating e(x)-1;
+   - e^(t/512 + delta[t]) is obtained from a table;
+   - n_1 + n_0 = n, so that |n_0| < DBL_MIN_EXP-1.
+
+   If it happens that n_1 == 0 (this is the usual case), that multiplication
+   is omitted.
