6c9678ebd4 Fix ldbl-128ibm expl overflow in non-default rounding modes (bug 19078).
The ldbl-128ibm expl wrapper checks the argument to determine when to
call __kernel_standard_l, thereby overriding overflowing results from
__ieee754_expl that could otherwise (given appropriately patched
libgcc) be correct for the rounding mode.  This patch changes it to
check the result of __ieee754_expl instead, as other versions of this
wrapper do.

Tested for powerpc.

	[BZ #19078]
	* sysdeps/ieee754/ldbl-128ibm/w_expl.c (o_thres): Remove variable.
	(u_thres): Likewise.
	(__expl): Determine whether to call __kernel_standard_l based on
	value of result, not argument.

d81f90ccd0 This patch renames all uses of __isinf*, __isnan*, __finite* and __signbit* to use standard C99 macros. This has no effect on generated code. 2015-06-03 15:41:36 +01:00

e42a38dd9d BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibm
The patch increase the high value to check if expl overflows. Current
high mark value is not really correct, the algorithm accepts high values.
It also adds a correct wrapper function to check for overflow and underflow.
