* Log2 and log10 for wordsize-64.Adhemerval Zanella2012-05-154-82/+305
| | | | This patch also fixes indentation on default dbl-64 code.
* Use __builtin_clzll on int64 in __logbH.J. Lu2012-05-141-1/+1

* Fix for logb/logbf/logbl (bugs 13954/13955/13956)Adhemerval Zanella2012-05-102-20/+30
| | | | | | | | POSIX 2008 states that if the input for 'logb[f|l]' is a subnormal number it should be treated as if it were normalized. This means the implementation should calculate the log2 of the mantissa and add it to the subnormal exponent (-126 for float and -1022 for double and IBM long double). This patch takes care of that.

* Fix ilogb exception and errno (bug 6794)Adhemerval Zanella2012-04-171-6/+2
| | | | | | | | | | | | | | | | | | | | [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.

* Create and use libc_feupdateenv_test.Richard Henderson2012-03-192-15/+22
| | | | | We can reduce the number of STMXCSR, and often we can avoid the call to __feraiseexcept.

|
* Make inline __isnan, __isinf_ns, __finite generic.Richard Henderson2012-03-191-0/+35
| | | | | | For code generation to stay identical on x86_64, this requires that we define the fp word manipulation macros before including the generic header.
