; The assumption 'p_2_loaded_from_var_0 <= 91' only holds if not 'p_2_loaded_from_var_0 >= 128'. Translation: if (trunc i64 %1 to i8) does not truncate any 1 bits, then we know that %1 <= 91.
; 'p_2_loaded_from_var_0 >= 128' must be in Invalid Context so we generate a RTC for it.
; 'p_2_loaded_from_var_0 <= 91' can only be in DefinedBehaviorContext, but not in "Context:" because "Context:" is used to gist AssumedContext and InvalidContext which would remove the required RTC: because %1 <= 91, the check if %1 >= 128 must not be optimized away.
