\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	[BZ #6794] Following Joseph comments about bug 6794, here is a proposed fix. It turned out to be a large fix mainly because I had to move some file along to follow libm files/names conventions. Basically I have added wrappers (w_ilogb.c, w_ilogbf.c, w_ilogbl.c) that now calls the symbol '__ieee754_ilogb'. The wrappers checks for '__ieee754_ilogb' output and set the errno and raise exceptions as expected. The '__ieee754_ilogb' is implemented in sysdeps. I have moved the 's_ilogb[f\|l]' files to e_ilogb[f\|l] and renamed the '__ilogb[f\|l]' to '__ieee754_ilogb[f\|l]'. I also found out a bug in i386 and x86-64 assembly coded ilogb implementation where it raises a FE_DIVBYZERO when argument is '0.0'. I corrected this issue as well. Finally I added the errno and FE_INVALID tests for 0.0, NaN and +-InF argument. Tested on i386, x86-64, ppc32 and ppc64.
*	Avoid overflows from long double functions using __kernel_standard.	Joseph Myers	2012-03-28	1	-0/+1

*	Create and use libc_feupdateenv_test.	Richard Henderson	2012-03-19	1	-0/+18
\| \| \| \| \|	We can reduce the number of STMXCSR, and often we can avoid the call to __feraiseexcept.
*	Create and use SET_RESTORE_ROUND{,_NOEX,_53BIT}{,F,L}.	Richard Henderson	2012-03-19	1	-0/+69

*	Convert libc_feholdexcept et al from macros to inline functions.	Richard Henderson	2012-03-19	1	-21/+78

*	Make inline __isnan, __isinf_ns, __finite generic.	Richard Henderson	2012-03-19	1	-13/+26
\| \| \| \| \| \|	For code generation to stay identical on x86_64, this requires that we define the fp word manipulation macros before including the generic header.
*	Implement and use libc_feholdexcept_setround_53bit and libc_feupdateenv_53bit	Andreas Jaeger	2012-03-14	1	-0/+5
\| \| \| \|	so that double arithmetic in s_sin is done in 53 bit (without extend i386 double precision)
*	Move math/math_private.h to sysdeps/generic/math_private.h.	Richard Henderson	2012-03-09	1	-0/+392
