Add an upstream to enable mp_set_double on more architectures to fix the following build failure on moarvm with some ARM architectures: linking moar ./libmoar.so: undefined reference to `mp_set_double' Fixes: - http://autobuild.buildroot.org/results/59d6b651498f3523d4a990eddc03c7d5043425ff Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

Subject: [PATCH] Build+test bn_mp_set_double.c on more platforms
|
|
|
|
Not all platforms/environments/architectures that support enough of
|
|
IEEE 754 for the purposes of mp_set_double() actually support enough
|
|
to legitimately define __STDC_IEC_559__, so only relying on that is
|
|
too strict. Fixes https://github.com/libtom/libtommath/issues/159
