I'm noticing that since I originally submitted this patch, a new keyword
has been added... isExact. Particularly in llvm/include/llvm/IRBuilder.h,
on the lshr and ashr operators.
I do not suppose that a circular shift can produce a poison value, but this
is a little out of my domain. Would someone more familiar with poison
values give me a bit of insight to them.
Ty,
Cameron
