* math/basic-test.c (TEST_FUNC): Replace NANFUNC argument with
|
||||
SUFFIX. Initialize qNaN_var with __builtin_nan family of
|
||||
functions.
|
||||
(TEST_TRUNC): Add SUFFIX argument. Initialize qNaN_var with
|
||||
__builtin_nan family of functions.
|
||||
* math/libm-test.inc (initialize): Initialize qnan_value with
|
||||
__builtin_nan family of functions.
|
||||
* sysdeps/powerpc/fpu/test-powerpc-snan.c (SNANf, SNAN, SNANl):
|
||||
Remove variables.
|
||||
(init_signaling_nan, snan_float, snan_double, snan_ldouble):
|
||||
Remove functions.
|
||||
(TEST_FUNC): Add SUFFIX argument. Move sNaN_var into static
|
||||
storage class. Initialize qNaN_var and sNaN_var with
|
||||
__builtin_nan and __builtin_nans families of functions,
|
||||
respectively.
|
||||
|
||||
* math/libm-test.inc (acosh_test): Also test with qNaN input.
|
||||
(sqrt_test): Remove duplicate test with qNaN input.
|
||||
(lrint_test, llrint_test, lround_test, llround_test, rint_test)
