[R-SIG-Mac] [External] Rmpfr on M1 Mac cause 'illegal trap'

[Simon Urbanek]

Jean,

yes it does by definition - the issue is the Intel translation on arm, so if you run native R there is no issue. There should be also no issue if you compile Intel mpfr on the M1 machine since it should detect capabilities correctly. Maybe I should have been more clear that the issue is that the binary we distribute has been compiled on CPU that has more capabilities than the Intel translation on M1 does. So compiling from source is the other alternative (whether native or not doesn't matter).

Cheers,
Simon
