-# WARNING: nasty hack.  Because sysnum.h produces thumb syscall
-# numbers when compiled in thumb mode the arm assembler (which is arm
-# even in thumb mode) needs to write the OS syscall base back into
-# the swi calls.  This is done here just by orring in the correct
-# value.  This is a hack - it might be better to add a define to
-# sysnum.h to force it to output arm (not thumb) values on demand -
-# but this hack is fairly safe (rmk would have to change the syscall
-# base, this seems unlikely).
-#
-# The patch also fixes up the .align directives to '2' (i.e. a multiple
-# of 4) not '4' (a multiple of 16 - apparently an error since it seems
-# to be unnecessary, there is no advantage here in cache line alignment).

-+ * Return the logarithm to base 2 of x
-+ *
-+ * Method :
-+ *   1. Argument Reduction: find k and f such that
-+ *			x = 2^k * (1+f),
-+ *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
-+ *
-+ *   2. Approximation of log(1+f).
-+ *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
-+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
-+ *	     	 = 2s + s*R
-+ *      We use a special Reme algorithm on [0,0.1716] to generate
-+ * 	a polynomial of degree 14 to approximate R The maximum error
-+ *	of this polynomial approximation is bounded by 2**-58.45. In
-+ *	other words,
-+ *		        2      4      6      8      10      12      14
-+ *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
-+ *  	(the values of Lg1 to Lg7 are listed in the program)
-+ *	and
-+ *	    |      2          14          |     -58.45
-+ *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2
-+ *	    |                             |
-+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
-+ *	In order to guarantee error in log below 1ulp, we compute log
-+ *	by
-+ *		log(1+f) = f - s*(f - R)	(if f is not too large)
-+ *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
-+ *
-+ *	3. Finally,  log(x) = k + log(1+f).
-+ *			    = k+(f-(hfsq-(s*(hfsq+R))))
-+ *
-+ * Special cases:
-+ *	log2(x) is NaN with signal if x < 0 (including -INF) ;
-+ *	log2(+INF) is +INF; log(0) is -INF with signal;
-+ *	log2(NaN) is that NaN with no signal.
-+ *
-+ * 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.
