+; FEX-Emu had a bug with its `TelemetrySetValue` IR operation where it would corrupt host flags at an inopportune time.
+; The IR operation does `cmp+cset`, but even with `ImplicitFlagClobber` set, this happened at a invalid time for flag handling.
+; To test this:
+;  - btr -> Sets CF
+;  - adc with `ss:` -> Adds to register with carry, but `ss:` causes `TelemetrySetValue`.
+;  - Host flags are corrupted after the `TelemetrySetValue`, before the `adc` was able to operate.
