Subject: [PATCH 17] Fix the C++ version of issignaling when
|
||
|
|
__NO_LONG_DOUBLE_MATH is defined
|
||
|
|
|
||
|
|
When __NO_LONG_DOUBLE_MATH is defined, __issignalingl is not available,
|
||
|
|
thus issignaling with long double argument should call __issignaling,
|
||
|
|
instead.
|
||
|
|
|
||
|
|
Tested for powerpc64le.
|
||
|
|
|
||
|
|
* math/math.h [defined __cplusplus] (issignaling): In the long
|
||
|
|
double case, call __issignalingl only if __NO_LONG_DOUBLE_MATH
|
||
|
|
is not defined. Call __issignaling, otherwise.
|
||
|
|
|
||
|
|
(cherry picked from commit 3d7b66f66cb223e899a7ebc0f4c20f13e711c9e0)
