arsenm added a comment.
Are you planning on adding codegen support in a separate patch?
None of these tests use llvm.convergence.point.
Can you also add tests for unroll with a convergent operation in the presence of the new intrinsics?
================
Comment at: llvm/docs/DynamicInstances.rst:229
+
+ void @llvm.convergence.point(token %anchor) convergent readnone
+
----------------
I don't fully understand what the 'point' of this one is. What is the point of ensuring nonreconvergence? Which real example does this correspond to?
