0fe0f1f86f Create and use libc_feupdateenv_test. 
We can reduce the number of STMXCSR, and often we can avoid the
call to __feraiseexcept.

eb92c487b3 Create and use SET_RESTORE_ROUND{,_NOEX,_53BIT}{,F,L}. 2012-03-19 06:49:44 -07:00

4851a949b4 Make inline __isnan, __isinf_ns, __finite generic. 
For code generation to stay identical on x86_64, this requires that
we define the fp word manipulation macros before including the
generic header.

c4814b6b3a Implement and use libc_feholdexcept_setround_53bit and libc_feupdateenv_53bit 
so that double arithmetic in s_sin is done in 53 bit (without extend i386 double precision)

7c10fd3515 Fix hypotf overflow/underflow by using double precision instead of scaling. 
[BZ #13840]
	* sysdeps/ieee754/flt-32/e_hypotf.c (__ieee754_hypotf): Rewrite to use
	double-precision for the calculation instead of scaling.

	large parameters.
