X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=01e094f82d8d91e08f62465a2e4f7a4c4897f9cd;p=platform%2Fupstream%2Fgcc.git

libstdc++: testsuite: use cmath long double overloads

In case we need to supplement the C standard library with additional
definitions for float and long double, the declarations expected to be
in the C headers may not be there.  Rely on the cmath overloads
instead.


for  libstdc++-v3/ChangeLog

	* testsuite/20_util/to_chars/long_double.cc: Use cmath
	long double overloads for nexttoward and ldexp.
