Subject: [RyuJIT/ARM32] Remove NYI: using zero register
X-Git-Tag: accepted/tizen/base/20180629.140029~1083^2~23^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a3e818db764fcc0629163d4a92e17443d33bbce1;p=platform%2Fupstream%2Fcoreclr.git

[RyuJIT/ARM32] Remove NYI: using zero register

We can remove NYI to using zero register to assign constant zero argument.
There is no zero register on ARM32. (src/jit/registerarm32.h)
So we can change the NYI to unreached() assertion.
