From this removal excluded is a workaround where we'd insert a `sideeffect` into clearly infinite loops such as `loop {}`. This code remains conditionally effective when the LLVM version is earlier than 12.0, which fixed the forward progress related miscompilations at their root. 2020-10-15T13:42:06+00:00 Mark Rousskov mark.simulacrum@gmail.com 2020-10-15T13:28:27+00:00 urn:sha1:e2efec89764f4ee68cc9f537eda722d2fb830bba Ideally, we would want to handle a broader set of cases to fully fix the underlying bug here. That is currently relatively expensive at compile and runtime, so we don't do that for now.
