Is anyone else seeing these failures with the latest glibc sources?
I am getting them on aarch64 (standard ToT sources) and was wondering
if this is an aarch64 specific problem or a more generic bug. Since
all the failures involve long double I don't think they are using
aarch64 specific code, but I could be wrong.
FAIL: math/test-ldouble-cexp
FAIL: math/test-ldouble-exp
FAIL: math/test-ldouble-finite-cexp
FAIL: math/test-ldouble-finite-exp
I think these failures are new and all of the failures listed are
about the Underflow exception being set:
I.e.
testing long double (without inline functions)
Failure: exp (-0x1p-10000): Exception "Underflow" set
Failure: exp (-0x2p-16384): Exception "Underflow" set
Failure: exp (-0x4p-16384): Exception "Underflow" set
Failure: exp (-0x4p-16448): Exception "Underflow" set
Failure: exp (-0x4p-16496): Exception "Underflow" set
Failure: exp (-0x8p-16448): Exception "Underflow" set
