[PATCH] D128525: Test and document stackmap corner case: when the frame size isn't statically known

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/test/CodeGen/SystemZ/stackmap-dynamic-alloca.ll:27
+  call void (i64, i32, ...) @llvm.experimental.stackmap(i64 0, i32 0, i32* %mem)
+  ret i32* %mem
+}
----------------
This is undefined behavior. The argument use is good enough
